R_C Pa-rE—VSv-zs nsr- zt- M, - - -_-Irk ELECTRICAL INSTALLATION ELECTRICAL REQUIREMENTS i) System Requirements REC panels are only for use where they meet the specific technical requirements of the complete system. Ensure other components do not cause mechanical or electrical damage to the panels. ii) Connection If panels are connected in series, they should have the same amp rating. If panels are connected in parallel, they should have the same voltage rating. ill) String configuration When using string configuration, plan and execute it according to inverter manufacturer's instructions. The number of panels connected to an inverter should be within the inverter voltage limits and operating range. Do not exceed the total system voltage permitted by the manufacturer, nor under any circumstance exceed the maximum system voltage of 600 V. The maximum reverse current is 15 A and the maximum series fuse rating is 15 A. iv) Wiring layout To minimize voltage surges (e.g. indirect lightning strikes), cables of the same string should be bundled together so loops are as small as possible. String configurations must be checked before commissioning. If open circuitvoltage (Vac) and short circuit current (Isc) deviate from specification, this may indicate a configuration fault. Correct DC polarity should be observed at all times. v) !unction box, connectors and materials The paneljunction box is rated IP67. All connectors and cables must be secure and tight as well as electrically and mechanically sound. UV -resistant cables and connectors approved for outside use must be used. Conductor gauge must ensure DC power losses (voltage drop) are kept to a minimum (< 1%). Observe all local regulations when selecting cables. For field connections, use minimum 12 AWG (4 mm') or copper wires insulated for a maximum operating temperature of 90'C. vi) Cable Management Cables must be secured using UV -resistant cable ties or other sunlight -resistant device. Loose and unsecured cables should be protected from damage (e.g. mechanical, abrasion, sharp objects, animals). As far as possible, avoid exposing cables to direct sunlight and permanent tension. vii) Electrical Ratings Under normal conditions, a photovoltaic panel is likely to experience consitions that produce more current and/or voltage than reported atSTC. The requirements of the National Electric Code (NEC) in Article 690 must be followed to address these increased outputs. In installations not under the requirements of the NEC, the values of Isc and Voc marked on the panels must be multiplied by a factor of 1.25 when determining component voltage ratings, conductor ampacities, overcurrent device ratings and size of controls connected to the PV output. SAFETY MEASURES Wiring installation shall be in accordance with the NEC (or CSA C22.1, Safety Standard for Electrical Installations, Canadian Electrical Code, Part 1 where applicable). All relevant electrical installation codes and regulations should be observed for regulations on working at heights and fat[ protection. i) Safety in -the working area Installation of REC Peak Energy panels may involve working on a roof. Ensure all local regulations regarding working at heights are followed. Before beginning work on a photovoltaic system, ensure aft working surfaces are structurally sound and capable of bearing the weight of employees and required equipment. Rememberto isolate the system from the grid before carrying out any maintenance or repair work. it) Preventing current generation Solar panels automatically generate current (electricity) when exposed to fight. To prevent this, shield the system with a non -transparent cover during installation, maintenance or repair work. ii) Specific hazards of DC electricity Solar panels generate direct current (DC). Once current is flowing, breaking or opening a connection (e.g. removing a DC cable from the inverter) can cause an electrical arc. Unlike low voltage AC wiring, DC arcs are not self -extinguishing. They are potentially lethal burn and fire hazards, capable of high temperatures that can destroy contacts and connectors: • Follow panel and inverter manufacturers' installation, handling and operating instructions • Remove/open the inverter AC fuse/circuit breaker before disconnecting from the public grid. • Switch off or disconnect the inverter and wait for the time specified by the manufacturer before commencing work. High -voltage components need sufficient time to discharge. iv) Safety requirements The voltage produced by a single pane[ and panels connected in series (voltages added together) or in parallel (currents added together) can be dangerous. Although the fully insulated plug contacts on the panel's output cables provide touch -safe protection, the following points must be observed during handlingto avoid the risk of sparking, fire hazards, burns and lethal electric shocks. • Excercise extreme caution when wiring panels and look outfor damaged or dirty cables etc. • Never insert metallic or other conductive objects into plugs or sockets. • Ensure that all electrical connections are completely dry before assembly. • Keep all materials, tools and working conditions dry and tidy. • Use appropriate safety equipment e.g. nonslip footwear, insulated gloves and insulated tools. • Solar panels produce current when exposed to sunlight. Do not connect the system to the inverter during solar exposure. f�i�a:F .a-�Sene=Inst�i=tir:Ms_a -.i. 0= R,1-0220" - MECHANICAL INSTALLATION FIRE GUIDELINES REC Peak Energy Series panels have a Class C Fire classification. Utilize the following fire safety guidelines when installing REC Peak Energy Series • Check with local authorities for fire safety guidelines and requirements for any building or structure on to which the panels will be installed_ • The system design should ensure that it can be easily accessed in the event of a building fire. • Check with local authorities for applicable regulations concerning setbacks or other placement restrictions that may applyfor roof -mounted arrays. • The use of DC ground fault interrupters is recommended. This may also be required by local and national codes. • All electrical appliances are a fire risk. The panel should therefore be mounted over a fire retardant roof covering rated for the application and a suitable distance of 4 in between the panel and the mounting surface, allowing free circulation of air beneath the panels, should be respected at all times. ORIENTATION To maximize system output, panels should be installed at the optimum orientation and tilt angle. The specifics of this depend on location and can be calculated by a qualified system designer. A lower angle of panel installation increases the requirement for regular cleaning. The optimal mounting position of panels results in the sun's rays falling perpendicular (i.e. at 90') to the surface. At[ panels in a string should, wherever possible, have the same orientation and tilt to ensure the system does not underperform due to mismatched outputs. The panels should not be exposed to artificially concentrated sunlight. ENVIRONMENTAL FACTORS REC Peak Energy Series panels are designed to provide decades of durable and stable output. Operating temperatures should be between -40 and 176°F (-40 and +80°C). The panels are not suitable for installation in potentially hazardous locations nor should they be installed in the following locations: • Near sources of flammable gases or vapors • Nearopenflames. • Under water or in water features. • Where exposed to sulfur e.g. near sulfur springs orvolcanoes. • Where the panels may be exposed to harmful chemicals. Ensure panels are not exposed to direct contact with salt water/spray and avoid installation in areas subject to high salt mist content e.g. coastalareas. PANEL HANDLING Panels should be handled with care. All warnings and instructions on the packaging should be observed. Follow these guidelines when unpacking, transporting or storing the panels: • Record the serial numbers prior to installation and note the information in the system documentation. • Carry the panels using both hands -and -avoid -using -the junction box as a grip. - - - -- -- • Do not allow the panels to sag or bow under their own weight when being carried. • Do not subject the panels to loads or stresses. Do not stand on them or drop them. • Keep all electrical contacts clean and dry. • Store panels in a dry and properly ventilated room. • Do not apply force to the backsheet. • Avoid using sharp or pointed objects if panels require marking. • Never apply paints, adhesives or detergents to the back of the laminate. • Do not use any solar panel that is damaged or been tampered with. • Never attempt to disassemble the panels. If the panel front glass is broken or laminate back sheet is damaged, it can expose personnel to hazardous voltages. PkVi-022 B MOUNTING THE PANELS REC Peak Energy Series panels are designed for capturing solar radiation and are not suitable for installation as overhead or vertical glazing. The panels are considered to be in compliance with UL 1703, only when the panel is mounted specified by the mounting instructions below. The REC junction box on the back of the panel is protected to IP67 and hence panels can be mounted in any orientation. PANEL INSTALLATION REC Peak Energy panels are typically installed on a rail -based mountingsystem. There are three different methods of installing an REC Peak Energy panel, each decribed below, depending on the design load of the array. The rails can run underthe frame or parallel to the frame, directly under the clamping zones (fig la & lb). Ensure the mounting structure is able to withstand anticipated wind and snow loads. Fig.1: Panel mounting options (a) Long side mounting using (b) Short side mounting using clamps (c) Mounting holes Ensure a minimum distance of 4 in (10 cm) between the uppermost part of the roof and the lowest part of the panel to ensure sufficient airflow beneath the panels and aid cooling. i) Rail specifications The clamps should be fastened to C or H channel rails (fig. 2). Thickness of walls for mechanical connections: min. 0.156 in (4.0 mm) Thickness of walls exposed to buckling load: min. 0.08 in (2.0 mm) Moment of Inertia for profile area about X-X: min array mounting diagram 00.4 in4 (19.2 cm4) Fig.2: Rail specification Walls for mechanical connectors Walls exposed to buckling load H channel rail The overlap between support rail and the outer edge of the panel frame must be a minimum of 1/64 in (6 mm). ii) Clamp Specification REC Peak Energy panels have been evaluated by UL for mounting using C-channel-rails in combination with end and mid clamps, 5/16 in (8 mm) ASTM F593C stainless steel screw and rail nuts. Alternatively clamps with the below ratings and dimensions can be used to secure the panel to the mounting structure (fig. 3): • Minimum yield strength of 2089 ton/ft2 (200 Mpa) • Minimum tensile strength of 2610 ton/ft2 (250 Mpa), e.g. 6005 T5 alloy. • Minimum grip length of US in (44.45 mm) • Minimum grip depth of 0.29 in (5 mm) • Minimum thickness of load carryingwalls of 0.156 in (4 mm) • Screw connection — 5/16 in (8 mm) stainless steel bolt, 5/16 in split washer (8 mm), nut Grip depth 0.2 in Fig.3: Clamp specifications :h in Walls exposed to load min 0.156 in Grip depth min 0.2 in Each panel must be securely fixed to the mounting structure at a minimum of four points (fig.4). r�i:?: jtrero�Szne_Ins[a3ix:.� _a-3 l'1= R�:I-OZ27%_ Fig. 4: An array mounting system with each panel secured at four points. iii) Mounting holes Mounting utilizing the four elongated holes (0.26 x 0.43 in (6.6 x 11 mm)) on the underside of the panel frame (at a distance of 17.72 in (450 mm) from the midpoint of the long side) have been found to comply with UL 1703 requirements for a maximum design load of 75.2 Ibs/ft2 (3600 Pa) (fig. 5). When mounting using mounting holes, the frame and panel edge must be supported by two transverse rails (fig.1, p 8), of aluminium orgalvanized steel to avoid galvanic corrosion and be appropriate for the local environment. These must be held in position by bolts and flange nuts accordingto the specifications below. If bought in a kit, do not use the washers and bottom mounted clips provided: When using mounting holes, fixings must be fastened to 9 f -lbs (12 Nm) of torque and installation must be according to fig. 6. PartName M;*tenal; Specification h b 1 t , Bolt ASTM F593 (stainless steel) 1/4" x 20 - 5/8" Flange Nut ASTM F594 (stainless steel) 1/4" x 20 Install the above parts as shown in fig. 6. Consult the Unirac Code Compliant Installation Manual for further details where necessary. For areas where discrepancy may exist, this installation manual shall take precedence. Fig.5: Mountingholes Mounting holes Fig. 6: Observe the following procedures when using mounting holes (fig. 5): • Additional electrical bonding to Earth is required for the support structure (see page 12). • All four mounting holes in the frame must be used -(for long or short -sided mounting orientation). • Fixings must be tightened to 9 ft lbs (12 Nm) using a torque wrench. R The warranty will be voided if additional holes are made in the frame. All fixing and fastening materials should be corrosion resistant. iv) Slide -in Systems REC Peak Energy panels have not been certified by UL for use with slide -in type mounting systems. If you have any questions regarding a mounting system and its suitability for REC Peak Energy panels, please contactyour local office for technical support. v) Drainage holes There are eight drainage holes, 0.47 x 0.30 in (12 x 7.5 mm) in the panels frame, each spaced 2.2 in (55 mm) from the corner of the panel frame (fig. 5). This allows water caused by rain or snow melt to exit the frame easily and minimizes the damage caused by freezing and thawing. Ensure these holes are not covered by any part of the mounting structure. Fig.7: Drainage holes R--CP E. !w-s-ti_'A3 vi) Long side mounting using clamps ' Mounting utilizing clamps on the two long sides of the panel have been found to be in compliance with UL 1703 requirements for a maximum design load of 75.2 lbs/ftz (3600 Pa) (fig. 8). • Clamps must be secured between a distance of 8.2 in to 16.4 in (208 mm - 416 mm) from the corner of the panel (measured from the mid -point) to the clamp edge. • Tightening torque must be tightened to 9 'IL-lbs (12 Nm). • The distance between the end clamp and the end of the rail must be minimum 1 in (25 mm). Fig. 8: Long Fig- 9: Short vii) Short side mounting using clamps Mounting utilizing clamps on the two short sides of the panel have been found to be in compliance with UL 1703 requirements for a maximum design load of 33.4 lbs%ftz (1600 Pa) (fig. 9). • Fix the panels so that the lower short side of the frame is supported by the mounting structure (to reduce risk of damages due to sliding snow load). • Clamps must be secured between tt a distance of 4.9 and 9.8 inches (125 - 250 mm) from the panel corner to the clamp edge. • Tightening torque must be tightened to 9 ft-lbs (12 Nm). • The minimum distance between the end clamp and the end of the rail is 1 in (25 mm). • Mechanical load must not exceed 33 4lbs/ft (1600 Pa). • The overlap between support rail and frame must be a minimum of in (6 mm). In areas of snow build-up, panels can be subjected to forces in excess of the stated limit even when snow depth does not appear extreme, causing damage to the framework. If the installation is likely to be affected, further suitable panel support is recommended on the lower row of panels. Ensure the drainage holes are not covered by the mounting structure. viii) Grounding A panel with exposed conductive parts is considered to be in compliance with UL 1703 only when the it is electrically grounded in accordance with the instructions presented below and the requirements of the NEC. Grounding is achieved through securement to the panel frame of the following UL Listed grounding Clips / Lugs in combination with the REC Peak Energy panel(s). • Suitable grounding lugs must be used: Listed (KDER) ILSCO, GBL-4DBT (tin plated) (E34440). • Grounding cable size should be between 4-14 AWG (2.1 mmz-21.2mmz). • Attach grounds to the grounding holes in the panel frames. • Fix lug to the frame using a star washer (#10) and lock nut (#10), ensuring a conductive connection (fig.10). Tighten according to manufacturer's instructions. Where common grounding hardware (nuts, bolts, star washers, split -ring lock washers, flat washers and the like) are used to attach a listed grounding/bonding device, the attachment must be made in conformance with the grounding device manufacturer's instructions.

Po{=��sF.c�r��:a=slrmta� ztix�l=ta -l.d_'(i2 R�1-022D'L MAINTENANCE CLEANING INSTRUCTIONS REC Peak Energy panels have been designed for easy maintenance. Normal rainfall will naturally clean the panels if installed at a sufficient angle. The need for cleaning will vary dependent on location, rainfall, pollution and angle of installation - the lower the angle of installation, the more cleaningwill be required. To optimize electrical output it is recommended to clean the panels when dirt can be seen on the glass surface. Cleaning of the panel should be carried out in the early morning when the panels are cool to avoid thermal shock. If dirt remains on the panel, it may cause cell shading which will reduce power output or even cause further damage. To clean either the front or rear of the panels, use only deionized water at ambient temperature and a sponge, microfiber cloth or a soft brush to wipe away the dirt (rainwater, tap water or diluted alcohol may also be used as a secondary solution). For further cleaning a mild, biological and biodegradable washing-up liquid may be used. When cleaning the panel, take care not to scratch the surface or introduce foreign elements that may cause damage. Ensure water used is free from grit and physical contaminants that may damage the panel. Always rinse the panel with plenty of water. If soiling remains, repeat the cleaning process. If stains require more effort to be removed, Iso-propyl alcohol of a concentration less than 10%. Acid or Alkali detergent may not be used AUse of high pressure hoses or clearners is not permitted as these may damage the panel, laminate or cells. Using a rubber squeegee, wipe the panel surface from the top downwards motion to remove any residual water from the panel glass. Panels can be left to dry in the air or wiped dry with a chamois. Avoid putting pressure on the panel surface when drying. For more information on cleaning REC panels, consult the Cleaning Information Sheet available to download from the online REC Installer Portal www. recgroup.com/installers. SYSTEM INSPECTION The system should be inspected regularly to ensure that: • Fasteners are secure, tight and free from corrosion. • Electrical connections are secure, tight, clean, and free of corrosion. • The mechanical integrity of the cables is intact. • Bonding points to ground are tight, secure and free from corrosion (which could break the continuity between the panels and ground). RECYCLING REC has made every effort to ensure panel packaging is kept to a minimum. The paper and cardboard packaging can be recycled and the protective wrapping and panel separating blocks are also recyclable in many areas. Please recycle according to local guidelines and regulations.

Unirac also provides a limited warranty on SolarMount products (page 26). N, 2 SolarMount is much more than a product. It's a system of engineered components that can be assembled into a wide variety of PV mounting structures. With SolarMount you'll be able to solve virtually any PV module mounting challenge. It's also a system of technical support: complete installation and code compliance documentation, an on-line SolarMount Estimator, person -to -person customer service, and design assistance to help you solve the toughest challenges. This is why SolarMount is PV's most widely used mounting system. AI ' %e installer is solely responsible for: • Complying with all applicable local or national building codes, including any that may supersede this manual; • Ensuring that Unirac and other products are appropriate for the particular installation and the installation environment; • Ensuring that the roof, its rafters, connections, and other structural support members can support the array under all code level loading conditions (this total building assembly is referred to as the building structure); • Using only Unirac parts and installer -supplied parts as specified by Unirac (substitution of parts may void the warranty and invalidate the letters of certification in all Unirac publications); • Ensuring that lag screws have adequate pullout strength and shear capacities as installed; • Verifying the strength of any alternate mounting used in lieu of the lag screws; • Maintaining the waterproof integrity of the roof, including selection of appropriate flashing; • Ensuring safe installation of all electrical aspects of the PV array; Ensuring correct and appropriate design parameters are used in determining the design loading used for design of the specific installation. Parameters, such as snow loading, wind speed, exposure and topographic factor should be confirmed with the local building official or a licensed professional engineer. SolarMount Unirac Code -Compliant Installation Manual 01 U N I R[ Part I. Procedure to Determine the Design Wind Load [1.1.] Using the Simplified Method - ASCE 7-05 The procedure to determine Design Wind Load is specified by the American Society of Civil Engineers and referenced in the International Building Code 2006. For purposes of this document, the values, equations and procedures used in this document reference ASEE.7-05, Minimum Design Loads for Buildings and Other Struatures..pleaserefer to ASCE 7-05 if you have any questions about the definitions or procedures presented in this manual Unirac uses Method 1, the Simplified Method, for calculating the Design Wind Load for pressures on components and cladding in this document. The method described in this document is valid for flush, no tilt, SolarMount Series application's:on either roofs or walls. Flush is defined as panels parallel to"the surface (or with no more than 3" difference between ends of assembly) with no more than 10" space between the roof surface, and the bottom of the PV panels. This method is not approved for open structure calculations. Applications of these procedures is subject to the following ASCE 7-05 limitations: 1. The building height must be less than 60 feet, h < 60. See note for determining h in the next section. For installations on structures greater than 60 feet, contact your local Unirac Distributor. 2. The building must be enclosed, not an open or partially enclosed structure, for example a carport. 3. The building is regular shaped with no unusual geometrical irregularity in spatial form, for example a geodesic dome. 4. The building is not in an extreme geographic location such as a narrow canyon or steep cliff. S. The building has a flat or gable roof with a pitch less than 45 degrees or a hip roofwltGa pitchress than 2Tdegrees. 6. if your installation does not conform to these requirements please contact your local Unirac distributor or a local professional engineer. if your installation is outside the United States.or does not meet all of these limitations, consult a local professional engineer or your local building authority. Consult ASCE 7-05 for more clarification on the use of Method I. Lower design wind loads may be obtained by applying Method H from ASCE 7-05. Consult with a licensed engineer if you want to use Method II procedures. The equation for determining the Design Wind Load for components and cladding is: pnet (psf) _ AKzJpnet30 p„er (psf) = Design Wind Load A = adjustmentfactor for height and exposure category Ka = Topographic Factor at mean roof height, h (ft) I = Importance Factor pnet3o (psf) = net design wind pressure for Exposure B, at height =30,1=1 You will also need to know the following information: Basic Wind Speed = V (mph), the largest 3 second gust of wind in the last 50 years. h (ft) = total roof height for flat roof buildings or mean roof heightforpitched roof buildings Roof pitch (degrees) This manual will help you determine: Effective Wind Area (sD = minimum total continuous area of modules being installed (Step 2) Roof Zone = the area of the roof you are installing the pv system according to Step 3. Roof Zone Dimension = a (ft) (Step 3) Exposure Category (Step 6) [1.2.] Procedure to Calculate Total Design Wind The procedure for determining the Design Wind Load can be broken into steps that include looking up several values in different tables. Table 5 has been provided as a worksheet for the following 9 steps (page 8) Step 1: Determine Basic Wind Speed, V (mph) Determine the Basic Wind Speed, V (mph) by consulting your Iocal building department or tocating your installation on the maps in Figure 1, page 4. Step 2: Determining Effective WindArea Determine the smallest area of continuous modules you will be installing. This is the smallest area tributary (contributing load) to a support or to a simple -span of rail. That area is the Effective Wind Area, the total area of the fewest number of modules on a run of rails. If the smallest area of continuous modules exceeds 100 sq ft, use 100 sq ft (See Table 2). If less, round down to values available in Table 2. PW 3 d U N I RAC Unirac Code -Compliant Installation Manual SolarMount mph Figure 1. Basic Wind Speeds. Adapted and applicable to ASCE 7-05.

Arrays may be located in more than one roof zone. Using Table 1, determine the Roof Zone Dimension Length, a (ft), according to the width and height of the building on which you are installing the pv system. 1463) 140(63) 0( 150(67) g r Spedal VYnd itegion 90 100(4(45) 110(49) -120(54) 130(58) 140(63) Miles per hour (meters per second) 140(63) M 150(67) Table I.

Step 5: Determine the Topographic Factor, Ast For the purposes of this code compliance document, the Topographic Factor, Kzt, is taken as equal to one (1), meaning, the installation is surrounded by level ground (less than 10% slope). If the installation is not surrounded by level.ground, please consult ASCE 7-05, Section 6.5.7 and the local building authority to determine the Topographic Factor. Step 6: Determine Exposure Category (B, C, D) Determine the Exposure Category by using the following definitions for Exposure Categories. The ASCE/SEI 7-05 defines wind exposure categories as follows: EXPOSURE B: is urban and suburban areas, wooded areas, or other terrain with numerous closely spaced obstructions having the size of single family dwellings. ExeosuRE c: has open terrain with scattered obstruc- tions having heights generally less than 30 feet. This category includes flat open country, grasslands, and all water surfaces in hurricane prone regions. EXPOSURE D: has flat, unobstructed areas and water sur- faces outside hurricane prone regions. This category includes smooth mud flats, salt flats, and unbroken ice. Also see ASCE 7-05 pages 287-291 for further explanation and explanatory photographs, and confirm your selection with the local building authority.

Procedure to Select Rail Span and Rail type [2.1.] Using Standard Beam Calculations, Structural Engineering Methodology The procedure to determine the Unirac SolarMount series rail type and rail span uses standard beam calculations and structural engineering methodology. The beam calculations are based on a simply supported beam conservatively, ignoring the reductions allowed for supports of continuous beams over multiple supports. Please refer to Part I for more information on beam calculations, equations and assumptions. If beams are installed perpendicular to the eaves on a roof steeper than a 4/12 pitch in an area with a ground snow load greater than 30psf, then additional analysis is required for side loading on the roof attachment and beam. In using this document, obtaining correct results is dependent upon the following: 1. Obtain the Snow Load for your area from your local building official. 2. Obtain the Design Wind Load, Pnet. See Part I (Procedure to Determine the Design Wind Load) for more information on calculating the Design Wind Load. 3. Please Note: The terms rail span and footing spacing are interchangeable in this document. See Figure 3 for illustrations. 4. To use Table 8 and Table 9 the Dead Load for your specific installation must be less than 5 psf, including modules and Unirac racking systems. If the Dead Load is greater than 5 psf, see your Unirac distributor, a local structural engineer or contact Unirac. The following procedure will guide you in selecting a Unirac rail for a flush mount installation. It will also help determine the design loading imposed by the Unirac PV Mounting Assembly that the building structure must be capable of supporting. Step 1: Determine the Total Design Load Figure 3. A spacing ar Page 10 The Total Design Load, P (psf) is determined using ASCE 7-05 2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow Loadl, S (psf), Design Wind Load, Pnet (psf) from Part I, Step 9 and the Dead Load (psf). Both Uplift and Downforce Wind Loads calculated in Step 9 of Part 1 must be investigated. Use Table 7 to calculate the Total Design Load for the load cases. Use the maximum absolute value of the three downforce cases and the uplift case for sizing the rail. Use the uplift case only for sizing lag bolts pull out capacities (Part 11, Step 6). Use the following equations or Table 7. P (psf) = LOD + 1.OS1 (downforce case 1) P (psf) = LOD + LOpnet (downforce case 2) P (psf) = LOD + 0.7551 + 0.75pnet (downforce case 3) P (psf) = 0.61) + I.Opnet (uplift) D = Dead Load (psf) S = Snow Load (psf) Pnet = Design Wind Load (psf) (Positive for downforce, negative for uplift) The maximum Dead Load, D (psf) is 5 psf based on market research and internal data. 1 Snow Load Reduction - The snow load can be reduced according to Chapter 7 ofASCE 7-05. The reduction is a function of the roof slope, Exposure Factor, Importance Factor and Thermal Factor. Please refer to Chapter 7 of ASCE 7-05 for more information. ivute: inuumes must oe cemerea symmerrically on the rails (+/- 2 *), as shown in Figure 3.

Step 2: Determine the WitriAwted Load on the rail, w (pV) Determine the Distributed Load, w (plfl, by multiplying the module length, B (ft), by the Total Design Load, P (ps, f) and dividing by two. Use the maximum absolute value of the three downforce cases and the Uplift Case. We assume each module is supported by two rails. w = PB/2 w = Distributed Load (pounds per linearfoot, pIf) B = Module Length Perpendicular to Rails (ft) P = Total Design Pressure (pounds per square foot, ps,9 Table 8. L-Foot SolarMount Series Rail Span SM - SolarMount HD - SobwHount Heavy Duty Step 3: Determine Rar1 Span/L Foot Spacing Using the distributed load, w, from Part 11, Step 2, look up the allowable spans, L, for each Unirac rail type, SolarMount (SM) and SolarMount Heavy Duty (HD). The L-Foot SolarMount Series Rail Span Table uses a single L-foot connection to the roof, wall or stand-off. Please refer to the Part III for more installation information. Pw 11 u N `RAC Unirac Code -Compliant Installation Manual SolarMount Step 4: Select Rail Type Selecting a span and rail type affects the price of your installation. Longer spans produce fewer wall or roof penetrations. However, longer spans create higher point load forces on the building structure. A point load force is the amount of force transferred to the building structure at each connection. It is the installer's responsibility to verify that the building structure is strong enough to support the point load forces. Table 10. Downforce Point Load Calculation Total Design Load (downforce) (max of case I, 2 or 3): P Module length perpendicular to rails: B Rail Span: L Downforce Point Load: age 12 R Step 5: Determine the Downforce Point Load, R (Ibs), at each connection based on rail span When designing the Unirac Flush Mount Installation, you must consider the downforce Point Load, R (lbs) on the roof structure. The Downforce, Point Load, R Qbs), is determined by multiplying the Total Design Load, P (psf) (Step 1) by the Rail Span L (ft) (Step 3) and the Module Length Perpendicular to the Rails, B (ft) divided by two. R (lbs) = PLB/2 R = Point Load (lbs) P = Total Design Load (psf) L = Rail Span (ft) B = Module Length Perpendicular to Rails (ft) It is the installer's responsibility to verify that the building structure is strong enough to support the maximum point loads calculated according to Step S. psf Step I x ft x ft Step 4 /2 lbs SolarMount Unirac Code -Compliant Installation Manual M U N I RA[ Step 6: Determine the Uplift Point Load, R (lbs), at each connection based on rail span You must also consider the Uplift Point Load, R (lbs), to determine the required lag bolt attachment to the roof (building) structure.

Install and seal flashings and standoffs using standard building practices or as the company providing roofing warranty directs. SolarMount Unirac Code -Compliant Installation Manual N U N I RAC [3.2.4] Installing SolarMount rails Keep rail slots free of roofing grit or other debris. Foreign matter will cause bolts to bind as they slide in the slots. Installing Splices: If your installation uses SolarMount splice bars, attach the rails together (Fig.13) before mounting the rails to the footings. Use splice bars only with flush installations or those that use low -profile tilt legs. Although structural, the joint is not as strong as the rail itself. A rail should always be supported by more then one footing on both sides of the splice. (Reference installation manual 908, Splices/Expansion Joints.) If using more than one splice per rail, contact Unirac concerning thermal expansion issues. Mounting Rails on Footings: Rails may be attached to either of two mounting holes in the L-feet (Fig: I4). Mount in the lower hole for a low profile, more aesthetica4 pleasing installation. Mount in the upper hole for a higher profile, which will maximize airflow under the modules. This will cool them more and may enhance performance in hotter climates. Slide the'/a-inch mounting bolts.into the footing bolt slots. Loosely attach the rails to the footings with the flange nuts. Ensure that the rails are oriented tathe footings as shown in Figure 8, 9, 11, or 12, whichever is appropriate. Aligning the Rail End: Align one pair of rail ends to the edge of the installation area (Fig.15 or Fig.16). The opposite pair of rail ends will overhang the side of the installation area. Do not trim them off until the installation is complete. If the rails are perpendicular to the rafters (Fig.15);.either end of the rails can be aligned, but the first module must be installed at the aligned end. If the rails are parallelto-the.rafters.(F g-16),.thealigned_endof the -rails must face the lower edge of the roof. Securely tighten all hardware after alignment is complete (30 ft lbs). Mount modules to the rails as soon as possible. Large temperature changes may bow the rags within a few hours if module placement is delayed. Edge of installation area • 1 1 1 Figure 15.

If modules have standard J-boxes, each module should be pre -wired with one end of the intermodule cable for ease of installation. For safety reasons, module pre -wiring should not be performed on the roof. Leave covers off J-boxes. They will be installed when the modules are installed on the rails. Installing the First Module: In high -profile installations, the safety bolt and flange nut must be fastened to the module bolt slot at the aligned (lower) end of each rail. It will prevent the lower end clamps and clamping bolts from sliding out of the rail slot during installation. If there is a return cable to the inverter, connect it to the first module. Close the J-box cover. Secure the first module with T-bolts and end clamps at the aligned end of each rail. Allow half an inch between the rail ends and the end clamps (Fig.18). Finger tighten flange nuts, center and align the module as needed, and securely tighten the flange nuts (10 ft lbs). Installing the Other Modules: Lay the second module face down (glass to glass) on the first module. Connect intermodule cable to the second module and close the J-box cover. Turn the second module face up (Fig.17). With T-bolts, mid -clamps and flange nuts, secure the adjacent sides of the first and second modules. Align the second module and securely tighten the flange nuts (Fig.19). For a neat installation, fasten wire management devices to rails with self -drilling screws. Repeat the procedure until all modules are installed. Attach the outside edge of the last module to the rail with end clamps. Trim off any excess rail, being careful not to cut into the roof. Allow half an inch between the end clamp and the end of the rail (Fig. 18). High -lipped module (cross section) •. Figure 17 Figure 18 Figure 19 J-boxes Low -lipped module (cross section) Figure 20.

To significantly reduce its likelihood, (1) apply lubricant to bolts, preferably an anti -seize lubricant, available at auto parts stores, (2) shade hardware prior to installation, and (3) avoid spinning on nuts at high speed. See Installation Supplement 910, Galling and Its Prevention, atwww.unirac.com. Np 21 g UNRRA[ Unirac Code -Compliant Installation Manual SolarMount [3.3.1] Planning the installation area Decide on an arrangement for clips, rails, and L-feet (Fig. 22) Use Arrangement A if the full width of the rails contacts the module. Otherwise use Arrangement B. Caution: If you choose Arrangement B, either (I) use the upper mounting holes of the L feet or (2) be certain that the L feet and clip positions don't conflict. If rails must be parallel to the rafters, it is unlikely that they can be spaced to match rafters. In that case, add structural supports - either sleepers over the roof or mounting blocks beneath it. These additional members must meet code; if in doubt, consult a professional engineer. Never secure the footings to the roof decking alone. Such an arrangement will not meet code and leaves the installation and the roof itself vulnerable to severe damage from wind. Leave enough room to safely move around the array during installation. The width of a rail -module assembly equals the length of one module. Note that L-feet may extend beyond the width of the assembly by as much as 2 inches on each side. The length of the assembly equals the total width of the modules.

Clip Arrangements A and B SolarMount Unirac Code -Compliant Installation Manual U U N I RA[ [3.3.2] Laying out the installing L-feet L-feet are used for installation through existing low profile roofing material, such as asphalt shingles or sheet metal. They are also used for most ground mount installations. To ensure that the L-feet will be easily accessible during flush installation: • Use the PV module mounting holes nearest the ends of the modules. • Situate the rails so that footing bolt slots face outward. The single slotted square side of the L-foot must always lie against the roof with the double -slotted side perpendicular to the roof. Foot spacing (along the same rail) and rail overhang depend on design wind loads. Install half the L-feet: • If rails are perpendicular to rafters (Fig. 23), install the feet closest to the lower edge of the roof. • If rails are parallel to rafters (Fig. 24), install the feet for one of the rails, but not both. For the L-feet being installed now, drill pilot holes through the roofing into the center of the rafter at each lag screw hole location. Squirt sealant into the hole and onto the shafts of the lag screws. Seal the underside of the L-feet with a sealant. Securely fasten the L-feet to the building structure with the lag screws. Ensure that the L-feet face as shown in Figure 23 or Figure 24. Hold the rest of the L-feet and fasteners aside until the panels are ready for the installation.

Align the edges of the modules and snug them together (Fig. 21, page 22). Trim the rails to the total width of the modules to be mounted. Place a rail adjacent to the outer mounting holes. Orient the footing bolt slot outward. Place a clip slot adjacent to the mounting holes, following the arrangement you selected earlier. Assemble the clips, mounting bolts, and flange nuts. Torque the flange nuts to 10 foot-pounds. [3.3.4] installing the module -rail assembly Bring the module -rail assembly to the installation site. Keep rail slots free of debris that might cause bolts to bind in the slots. Consider the weight of a fully assembled panel. Unirac recom- mends safety lines whenever lifting one to a roof. Align the panel with the previously installed L-feet. Slide 3/8 inch L-foot mounting bolts onto the rail and align them with the L-feet mounting holes. Attach the panel to the L-feet and finger tighten the flange nuts. Rails may be attached to either of two mounting holes in the footings (Fig. 25). • Mount in the lower hole for a low, more aethetically pleasing installation. • Or mount in the upper hole to maximize a cooling airflow under the modules. This may enhance perfor- mance in hotter climates. Adjust the position of the panel as needed to fit the installa- tion area. Slide the remaining L-feet bolts onto the other rail, attach L-feet, and finger tighten with flange nuts. Align L-feet with mounting holes previously drilled into the roof. Install lag bolts into remaining L-feet as described in "Laying out and installing L-feet' above. Torque all footing flange nuts to 20 foot-pounds. Verify that all lag bolts are securely fastened.

Tampering with or opening the Enphase Microinverter will void the warranty. • Before installing or using the Enphase Microinverter, please read all instructions and cautionary markings in the technical description and on the Enphase Microinverter System and the PV equipment. ■ Connect the Enphase Microinverter to the utility grid only after receiving prior approval from the electrical utility company. ■ Be aware that the body of the Enphase Microinverter is the heat sink. Under normal operating conditions, the temperature is 150C above ambient, but under extreme conditions the microinverter can reach a temperature of 80°C. To reduce risk of burns, use caution when working with microinverters. • Do NOT disconnect the PV module from m the Enphase Microinverter without first removing AC power. Page 4 copyright Enphase Energy Inc. 2011 141-00012, Rev 02c enphase ENERGY The Enphase Microinverter System The Enphase Microinverter System is the world's most technologically advanced inverter system for use in utility -interactive applications. This manual details the safe installation and operation of the Enphase Microinverter. The three key elements of an Enphase Microinverter System include the: • Enphase M215 Microinverter • Enphase EnvoyTM Communications Gateway • Enphase Enlighten TM web -based monitoring and analysis software This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation and management. Q Enphase Microinverters • installed on the racking beneath each solar module • maximize energy harvest 19 AC power travels over AC wiring to the load center • performance data is also sent via the AC wiring • plug and play communications 0 Envoy Communications Gateway • plugs into any AC outlet • collects information_via the AC wiring • transmits data through a standard broadband router to the Internet ® Standard Broadband Router • information collected by the Enphase Envoy is then transmitted to Enlighten in 5-minute intervals ® Enphase Enlighten Monitoring • provides monitoring and analysis • performance information can be viewed from any web browser Page 5 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase E N E R G Y How the Microinverter Works The Enphase Microinverter maximizes energy production from your photovoltaic (PV) array. Each Enphase Microinverter is individually connected to one PV module in your array. This unique configuration means that an individual Maximum Peak Power Point Tracker (MPPT) controls each PV module. This ensures that the maximum power available from each PV module is exported to the utility grid regardless of the performance of the other PV modules in the array. That is, although individual PV modules in the array may be affected by shading, soiling, orientation, or PV module mismatch, the Enphase Microinverter ensures top performance for its associated PV module. The result is maximum energy production from your PV system. System Monitoring Indoors, you can install the Envoy Communications Gateway by plugging it into any convenient 120Vac wall socket and providing an Ethernet connection to your broadband router or modem. After installation of the Envoy, the Enphase Microinverters automatically begin reporting to the Enphase Enlighten web server. The Enlighten software presents current and historical system performance trends, and it informs you when the PV system is not performing as expected. aptimai Reliability Microinverter systems are inherently more reliable than traditional inverters. The distributed nature of a microinverter system ensures that there is no single point of system failure in the PV system. Enphase Microinverters are designed to operate at full power at ambient temperatures as high as 650 C (1500 F). The microinverter housing is designed for outdoor installation and complies with the NEMA 6 environmental enclosure rating standard:' NEMA 6 rating definition: Indoor or outdoor use primarily to provide a degree of protection against hose -directed water, and the entry of water during occasional temporary submersion at a limited depth, and damage from external ice formation. Ease of Design PV systems using Enphase Microinverters are very simple to design and install. You will not need string calculations, and you can install individual PV modules in any combination of PV module quantity, type, age and orientation. You won't need to install cumbersome traditional inverters. Each microinverter quickly mounts on the PV racking, directly beneath each PV module. Low voltage DC wires connect from the PV module directly to the co -located microinverter, eliminating the risk of personnel exposure to lethal 600Vdc power. Page 6 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase E N E R G Y Enphase Microinverter Installation Follow the instructions in this section to install Enphase M21511' Microinverters. WARNING: Be aware that only qualified personnel should connect the Enphase Microinverter to the utility grid. WARNING: Be aware that installation of this equipment includes risk of electric shock. Normally grounded conductors may be ungrounded and energized when a ground fault is indicated. Compatibility and Capacity The Enphase M215 Microinverters are electrically compatible with most 60-cell PV modules. For more information, see Technical Data page 25 of this manual. . WARNING: The M215 should be paired only with a 60-cell PV module. Refer to the Enphase website (http:!lwww.enphase.comisupport/downloads) for a list of electrically -compatible PV modules and approved PV racking systems. To ensure mechanical compatibility, be sure to order the correct connector type for both microinverter and PV module from your distributor. Electrical Compatibility M215-60-2LL-S23 Capacity -- - 60 cel I . _ 60 cell MC-4 Type 2 Locking or Amphenol H4 Locking Tyco Solarlock Locking Page 7 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase ENERGY Parts and Tools Required In addition to the M215 Microinverters, PV modules, racking, and associated hardware, you will need the following items. Enphase equipment: • Engage Cable, as needed • Cable clips • Sealing caps, as needed (for any unused drops on the Engage Cable) • Terminators, as needed (one needed at the end of each AC branch circuit) • Enphase disconnect tool (a number 2 Phillips screwdriver can be substituted) Other items: • AC junction boxes Gland or strain relief fitting (one per AC junction box) • Continuous grounding conductor, grounding washers • Number 2 Phillips screwdriver • Torque wrench, sockets, wrenches for mounting hardware • Adjustable wrench or open-ended wrench (for terminators) • Handheld mirror (for viewing indicator lights on the undersides of the mirrninverters) Lightning Surge Suppression Lightning does not actually need to strike the equipment or building where PV system is installed to cause damage. Often, a strike nearby will induce voltage spikes in the electrical grid that can damage equipment. Enphase Energy Microinverters have integral surge protection, greater than most traditional inverters. However, if the surge has sufficient energy, the protection built into the Microinverter can be exceeded, and the equipment can be damaged. Since the Enphase Limited Warranty does not cover "acts of God" such as lightning strikes, and since lightning strikes can occur anywhere, it is best practice to install surge protection as part of any solar installation. We recommend the following protection device. It has been tested to ensure that it does not interfere with power line communications. Install per vendor instructions. Vendor: Cite[, Part Number: DS72RS-120 Application: Residential 120/240V Split Phase where N-G bond exists. See the vendor datasheet for DS70R, (which includes the DS72RS-120) at http://www.citelprotection.com/encilish/citel data sheets/ac protection/. Page 8 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase ENERGY Installation Procedure Installing the Enphase Microinverter System involves several key steps. Each step listed below is detailed in the following pages. Step 1 - Measure AC at the Electrical Utility Connection Step 2 - Install the AC Branch Circuit Junction Box Step 3 - Position the Enphase Engage Cable Step 4 - Attach the Microinverters to the PV Racking Step 5 -Dress the Enphase Engage Cable Step 6 - Terminate the Unused End of the Engage Cable Step 7 - Connect the Engage Cable to AC Junction Box(es) Step 8 - Ground the System Step 9 - Complete the Installation Map Step 10 - Connect the PV Modules Step 11 - Build the Virtual Array WARNING: DO NOT connect Enphase Microinverters to the utility grid or energize the AC circuit(s) until you have completed all of the installation procedures as described in the following sections. Step 1 - Measure AC at the Electrical Utility Connection Measure AC line voltage at the electrical utility connection to confirm AC service at the site. Acceptable ranges are shown in the following table. Ll to L2 211 to 264 Vac Ll, L2 to neutral 106 to 132 Vac c.ccc a Ll to L2 to L3 183 to 229 VAC L1, L2, L3 to neutral 106 to 132 VAC Volt Meter AC Distribution Panel • NOTE: Be sure the Engage Cable you are using matches the electrical utility connection at the site. Use 208 Vac (208 Vac three-phase) Engage Cable at sites with three-phase 208 Vac service, or use 240 Vac Engage Cable at sites with 240 Vac single-phase service. Check the labeling on the drop connectors to verify the voltage type. Page 9 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c enphase E N E R G Y IWV Step 2 - Install the AC Branch Circuit ]unction Box DANGER: Risk of Electrical Shock. Be aware that installation of this equipment includes risk of electric shock. Do not install the AC junction box without first removing AC power from the Enphase System. WARNING: Only use electrical system components approved for wet locations. WARNING: Do NOT exceed the maximum number of microinverters in an AC branch circuit as listed on page 27 of this manual. You must protect each microinverter AC branch circuit with a 20A maximum breaker. a. Size the AC wire gauge to account for voltage drop. Select the correct wire size based on the distance from the beginning of the microinverter AC branch circuit to the breaker in the load center_ All components of system wiring must be considered, including internal voltage drop within the length of Engage Cable. Typically, three wire sections and several wire terminations must be quantified. There is also some resistance associated with each circuit breaker. As all of these resistances are in series, they add together. Since the same current is flowing through each resistance, the total voltage drop is total current times the total resistance. For a single-phase system, the total resistance is equal to two times the one-way resistance. For a three-phase system, each of the three line currents and resistances must be calculated. Standard guidelines for voltage drop on feeder and AC branch circuit conductors might not be sufficient for microinverter AC branch circuits that contain the maximum allowable microinverters. This is due to high inherent voltage rise on the AC branch circuit. For more information, refer to our Voltage Drop Calculations Application Note at http://www.enphase.com/support/downloads. b. Install an appropriate junction box at a suitable location on the PV racking system (typically at the end of a row of PV modules). c. Provide an AC connection from the AC junction box back to the electrical utility connection using equipment and practices as required by the NEC and local jurisdictions. A Page 10 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c C�l enphase J E N E R G Y Step 3 - Position the Enphase Engage Cable The Engage Cable is a continuous length of 12 AWG (2.5 mm2), outdoor rated cable with integrated connectors for microinverters. These connectors are preinstalled along the Engage Cable at intervals to accommodate PV module widths. The microinverters plug directly into the connectors, and the Engage Cable is terminated into the junction box that feeds electricity back to the system AC disconnect. a. Lay the Engage Cable along the route it will travel, positioning the connectors so that they align with the PV modules. WARNING: Plan the AC branches so that they do not exceed the maximum number of microinverters in an AC branch circuit as listed on page 27 of this manual. You must protect each microinverter AC branch circuit with a 20A maximum breaker. NOTE: =.Many PV modules have a central stiffening brace. In these cases, do not position the connector and microinverter at the exact center of the PV module, but position the Engage Cable so that the connectors do not conflict with the braces. b. PV module widths vary by manufacturer. On the Engage Cable, connectors are spaced at intervals to allow for the widest PV modules compatible with Enphase Microinverters. If narrower PV modules are used, it may be necessary to account for excess cable by looping the cable at suitable intervals. Page 11 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e]enphase ENERGY Step 4 - Attach the Microinverters to the PV Racking a. Mark the approximate centers of each PV module on the PV racking. b. Evaluate the location of the microinverter with respect to the PV module DC junction box or any other obstructions. 71 c. Ensure that the microinverter does not interfere with the PV module frame or stiffening braces. d. Ensure that the connector from the microinverter can easily reach the connector on the Engage Cable. e. Allow a minimum of 1.9 cm (0.75 inches) between the roof and the bottom of the microinverter. Also allow 1.3 cm (0.50 inches) between the back of the PV module and the top of the microinverter. WARNING: Do not mount the microinverter in a location that allows long- term exposure to direct sunlight (i.e., the microinverter should be covered by the PV module). f. Ground the microinverters using either a continuous, unbroken l gr oul ldil lg conductor or approved grounding ldil lg washers. If using grounding washers (e.g., WEEB) to ground the microinverter chassis to the PV module racking, choose one that is approved for the racking manufacturer. Install one grounding washer per microinverter. Torque the microinverter fasteners to the values below. i 6 mm (1/4") mounting hardware - 5 N m (45 in -IDS) minimum • 8 mm (5/16") mounting hardware - 9 N m (80 in-Ibs) minimum NOTE: Using a power screwdriver to tighten the grounding clamp screw is not recommended due to the risk of thread galling. NOTE: Compatible grounding washer part numbers are included in the Racking Compatibility Application Note. Installation guidelines are included in the WEEB Installation Application Note. Refer to both at: http://www.enphase.com/support/downloads. g. With the silver side of the microinverter facing up and the black side facing down, mount one microinverter at each location using suitable hardware. The indicator light on the underside of the microinverter will be facing the roof. Page 12 copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase ENERGY Step S - Dress the Engage Cable a. Attach the Engage Cable to the PV racking using the cable clips, or you may use tie wraps. The cable clips are designed so that the connector from the microinverter can also be dressed into the clip underneath the Engage Cable. NOTE: There are two through -holes in the connector on the cable. These are not for mounting but are used to disconnect the connector. Keep these release holes clear and accessible. b. Dress any excess in loops so that the Engage Cable does not contact the roof Do not allow the Engage Cable to rest on the roof. There are several ways to support the cable. One method is to place tie wraps or clips on either side of the connector. Use one or two additional clips, tie wraps, or other support scheme to secure the cable between connectors. c. Remove the temporary shipping cap from the Engage Cable and connect the microinverter. There are two latching mechanisms within the connectors. Listen fortwoclicks as the connectors engage. Ensure that both latching mechanisms have engaged. I Page 13 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e] enphase ENERGY Nor Step 5 - Dress the Engage Cable (continued) d. Repeat for all microinverters in the AC branch circuit. e. Cover any unused connector with a sealing cap. Listen for two clicks as the connectors engage. Ensure that both latching mechanisms have engaged. Do not use the shipping cap to cover unused connectors. The shipping cap does not provide an adequate environmental seal. Enphase sealing caps are required for the system to be UL compliant and to protect against moisture ingress. NOTE: Enphase sealing caps are IP67 rated. Within the term "IP67", "IP" indicates an Ingress Protection (IP) rating against dust and liquids. This specific rating of IP67 indicates that this connector protects against all dust particles and immersion in liquid. WARNING: Make sure protective sealing caps have been installed on all unused AC connectors. Unused AC connectors are live when the system is energized by the utility system. NOTE: If you need to remove a sealing cap, you must use the Enphase disconnect tool or a #2 Phillips screwdriver. Sealing caps may not be reused. Page 14 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c enphase [e] :k E N E R G Y low Step 6 - Terminate the Unused End of the Engage Cable Terminate the far end of the Engage Cable. a. Remove 60mm (2.5 inches) of the cable sheath from the conductors. b. Slide the hex nut onto the Engage Cable. c. Insert the Engage Cable all the way into the wire organizer (up to the stop). d. hex nut wire organizer cap Bend the individual wires back into the recesses in the wire organizer so that they angle back toward the cable. e.Cut the individual wires so that no excess extends outside of the wire organizer. The portions that angle back will need to extend enough to fit :neatly into the 0.5 cm (0.2 in) recesses in the wire organizer and flush with the edge of the cap. f. Screw the hex nut onto the cap. Never unscrew the hex nut as this can twist and damage the cable. g. Hold the cap with an Enphase disconnect tool, or insert a #2 Phillips h. Use a 24mm (7/8 inch) wrench to tighten the hex nut until the latching mechanism is screwed all the way to the base. L Use a tie wrap or cable clip to attach the cable to the PV racking, so that the Engage Cable and terminator do not touch the roof. j. Ensure that all cabling is located underneath the PV module. Page 15 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c enphase E N E R G Y Step 7 - Connect the Engage Cable to AC ]unction Box(es) a. Connect Engage Cable into the AC branch circuit junction box using an appropriate gland or strain relief fitting. The Engage Cable requires a strain relief connector with an opening of 1.3 cm (0.5 inches) in diameter. b. Connect the Engage Cable into additional AC junction boxes as needed to transition to conduit between smaller sub -arrays. Refer to the wiring diagrams located in the Appendix of this manual for more information. NOTE: The Engage Cable uses a different wiring scheme than used with other Enphase Microinverters. Be aware of the difference in wire color code. Wires are identified as follows: L1 is sheathed in Black, L2 is sheathed in red, L3 is sheathed in blue, Neutral is sheathed in white, and Ground is sheathed in green. The grounding wire is used to ground the microinverters. A WEEB or continuous ground is required in addition to this green grounding wire. Balanced 208 VAC is accomplished by alternating phases between microinverters. Black - Ll Red - L2 White - Neutral Green - Ground Black - Ll Red - L2 Blue - L3 White - Neutral Green - Ground NOTE: The green wire acts as equipment ground. A continuous GEC for system ground is also required as described in the next step. Page 16 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c [e]enphase E N E R G Y Step 8 - Ground the System If you are not using WEEB grounding washers to ground the microinverter chassis as described in step 4, follow the steps below. Each Enphase Microinverter comes with a cable clip that .can accommodate a 6-8 AWG conductor. NOTE: The AC output neutral is not bonded to ground inside the microinverter. a. Route a continuous GEC through each of the microinverters to the NEC - approved AC grounding electrode. b. You can ground the PV racking and PV module to this conductor using.a crimp connection. An alternative method is to connect the microinverter to the grounded racking using a grounding washer approved for the racking. c. Torque the microinverter fasteners to the values below. 6 mm (1/4") mounting hardware - 5 N m (45 in-Ibs) minimum • 8 mm (5/16") mounting hardware - 9 N m (80 in-Ibs) minimum NOTE: Using a power screwdriver to tighten the grounding clamp screw is not recommended due to the risk of thread galling. Page 17 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c enphase [e] E N E R G Y Step 9 - Complete the Paper Map The Enphase Installation Map is a diagrammatic representation of the physical location of each microinverter in your PV installation. The virtual array in Enlighten is created from the map you create. Use the blank map in the Appendix to record microinverter placement for the system, or provide your own layout if a larger or more intricate installation map is required. Complete the Enphase Map a. Each Enphase Microinverter has a removable serial number label located on the mounting plate. Peel the removable serial number label from each Enphase Microinverter and affix it to the respective location on the Enphase installation map (see map on page 28). Remember to keep a copy of the installation map for your records. Alternative: Create Your Own Map a. Draw a top -down view of the array using the Array Map template (using either the grid on Side A or the freeform area on Side B). Make sure to leave enough room to place the serial number stickers. b. When installing the microinverters, remove the serial number labels located next to the DC input cables and place them in the correct order on your drawing of the system. Remember to keep a copy of the installation map for your records. Step 10 - Connect the PV Modules NOTE: Completely install all microinverters and all system AC connections prior to installing the PV modules. a. Mount the PV modules above the microinverters. b. Mate the microinverters and PV modules as required. Repeat for all remaining PV modules using one microinverter for each PV module.

If the disconnect tool is not available, a #2 Phillips screwdriver can be used in its place. Insert the screwdriver into one hole, rock that side of the drop connector out, then insert the screwdriver into the other hole and pull the connector out entirely. 2. Cover the PV module with an opaque cover. 3. Using a clamp on meter, verify there is no current flowing in the DC wires between the PV module and the microinverter. 4. Take care when measuring DC current as most clamp -on meters must be zeroed first and tend to drift with time. S. Disconnect the PV module DC wire connectors from the microinverter using the Enphase disconnect tool. 6. Remove the microinverter from the PV racking. WARNING: Do not leave the AC connector on the Engage Cable uncovered for an extended period. If you do not plan to replace the microinverter immediately, you must cover any unused connector with a sealing cap. Page 23 Copyright Enphase Energy Inc. 2011 141-00012, Rev 02c re enphase l E N E R G Y Installing a Replacement Microinverter 1. With the silver side of the microinverter facing up and the black side facing down, attach the replacement microinverter to the PV racking using hardware recommended by your PV racking vendor. 2. If you are using grounding washers (e.g., WEEB) to ground the chassis of the microinverter, the old grounding washer should be discarded, and a new grounding washer must be used when installing the replacement microinverter. Torque the microinverter fasteners to the values below. • 6 mm (1/4") mounting hardware - 5 N m (45 in-Ibs) minimum 8 mm (5/16") mounting hardware - 9 N m (80 in-Ibs) minimum NOTE: Using a power screwdriver to tighten the grounding clamp screw is not recommended due to the risk of thread galling. 3. If you are using a grounding electrode conductor to ground the microinverter chassis, attach the grounding electrode conductor to the microinverter ground clamp. 4. Remove the temporary shipping cap from the Engage Cable and connect the microinverter. There are two latching mechanisms within the connectors. Listen for two clicks as the connectors engage. Ensure that both latching mechanisms have engaged. S. Mount the PV module above the microinverter. 6. First connect the positive DC wire from the PV module to the negatively marked DC connector (male pin) of the microinverter. Then connect the negative DC wire from the PV module to the positively marked DC connector (female socket) of the microinverter. 7. Energize the AC branch circuit breaker, and verify operation of the replacement microinverter by checking the indicator light on the underside of the microinverter. You may need a handheld mirror to see the indicator light. S. Initiate a device scan at the Envoy. To do this, press and hold the Menu button on Envoy for two seconds to bring up the Envoy menu on the LCD window. When the LCD window displays "Enable Communication Check", release the Menu button. 9. Use Enlighten's Array Builder function to add the newly detected microinverter to the virtual array.

Be sure to verify the voltage and current specifications of your PV module match those of the microinverter. For more information, refer to the Enphase website (htto://www.enphase.com/support/downloads) for a list of compatible PV racking and PV modules. WARNING: You must match the DC operating voltage range of the PV module with the allowable input voltage range of the Enphase Microinverter. WARNING: The maximum open circuit voltage of the PV module must not exceed the specified maximum input voltage of the Enphase Microinverter. The output voltage and current of the PV module depends on the quantity, size and temperature of the PV cells, as well as the insolation on each cell. The highest PV module output voltage occurs when the temperature of the cells is the lowest and the PV module is at open circuit (not operating). The maximum short circuit current rating of the PV module must be equal to or less than the maximum input DC short circuit current rating of the microinverter. A list of compatible PV modules is maintained on the Enphase website (httr)://www.enphase.com/supgort/downloads).
