A)ELECTRICAL REQUIREMENTS Application Class: Modules are rated for use in application class A(general access,hazardous voltage,hazardous power applications'according to IEC 617K System Requirements: REC photovoltaic(PV)modules should only be usedin systems where they meet the speci5c technical requirements of the system as a whole.Ensure that other system components will not cause mechanical or electrical damage to the modules. Connection: • If the modules are to be connected together in series,they should have the same amperage. • if the modules are to be connected in parallel,they should have the same voltage. String configuration: If you use string configuration,plan and execute it according to the inverter manufacturer's instructions. The number of.-nodules connected to an inverter should be wvithin the inverter voltage limits and operating range.The design of the string configuration(s)should comply with the inverter's manufacturer's guidelines and must create a voltage less than the permitted total system voltage. Wiring layout and configuration In order to minimize voltage surges which could be induced by indirect lightning strikes,DC cables of the same string should be bundled together so that loops are kept as small as possible.String configuratiors should be checked before system commissioning.If the open circuit voltage(Voc)and the short circuit current Osr_)deviates from the specifications,this could indicate a conr":.guration fault Correct DC polarity should be observed at all times. Connection of plug connectors Ail connections should be secure,tight and electrically and mechanically sound. Accessories and materials UV-resistant cables and connectors approved for outside use should be used.Ensure that they are electrically and.-mechanically sound.Conductor gauge should be chosen so as to ensure that DC power losses(voltage drop)are kept to a minimum(less than 1%is preferred).National Electrical --ode(NEC) and regulations need to be followed rohen selecting cables.For field connections,use minimum 4 mm'or #.12 A'Oju'copper wires insulated For a minimum of 90'C. Protecting the cables Cables should be secured to the array mounting system using UV-resistant cable ties,or other sunhght- resistant device.Loose and unsecured cables should be protected from mechanical damage.Avoid,as far as possible,exposing the cables to direct sunlight and permanent tension. Grounding(USA and Canada only) You must ground all PV modules,using an electrical connection From the, odule frames to the ground.This must be done according to tf,e Following standards: • Use a UL-listed grounding lug,such as the tin-piated versions of ILSCO GBL-4DB or CMC CL 50-DB lay-in lugs,or their equivalent. • Attach the grounds to the existing grounding holes in the module frames. • To ensure a conductive connection use a combination of screw,star washer and lock nut to mount the grounding lug onto the f ame. • Place the star washer between the frame and the nut,use Size#10 stainless steel screw,washer and locking nut to mount the lug to the module frame,and tighten with 5 ft-lbs(6.8 Nm)torque, • The grounding wire size should be between 4 AWG and 14 AWG(21.2mm'-2.1 mm ). • Canada:The installation shall be n accordance with CSA 022.1,safety standard for electrical installations,Canadian electrical code,part 1. • The torque for wire fastening should be in accordance with the following table GROUNDING DIMENSIONS AND TORQUE Wire size[AWG] Cross section[mm2[ Type Torque Torque Torque [in-I.bs[ [ft-lbs; [Nmj 4-6 2 12- 13.3 Stranded 3S 29 3.9 8 8.4 Stranded 30 2.5 3.4 iC-14 S3-2 i Stranded�Solid 25 21 2.8 GROUNDING Laminate Frame Star Washer u Grounding Cable �`� B)RATINGS Values at Standard Test Conditions See Electrical data table For STC Characteristics(Irradiance level 1000 W/m2,Cell temperature 25'C, spectrum AM 1,5).

Refer to section 690.8 of the US National Electric Code(NEC)for an additional multiplying factor of 125%(80%derating)which may be applicable_ The multiplying factor for the open circuit voltage of the module(Voc)is according to Table 690.7 of the NEC code. C)ELECTRICAL SAFETY All relevant electrical installation codes and regulations should be referred to and observed.A copy of these instructions should be included in the system documentation. Preventing the system from generating current Solar modules automatically generate current(electricity)when exposed to light.To prevent this,shield the system with a non-transparent cover during installation,maintenance or repair work. Unique Hazards of DC Electricity Solar modules generate direct current(DC)electricity.Once the current is flowing,breaking or opening a connection(e.g.disconnectinga DC cable from the inverter)can cause a DC electrical arc.Unlike arcs occurring in conventional.low voltage AC wiring,DC arcs are not self-extinguishing.They are a potentially lethal burn and fire hazard,capable of creating high temperatures that can destroy contacts and connectors. Always: • Follow the module and inverter manufacturer's installation,handling and operating instructions • Remove/open the inverter AC fuse/circuit breaker before you disconnect the inverter from the public grid • Switch off or disconnect the inverter and wait for the time specified by the manufacturer before working on it-its high-voltage components need sufficient time to discharge. Safety Requirements: The voltage produced by individual modules and modules connected in series(voltages are added together)or in parallel(currents are added together),can give rise to dangerous voltage and current. 7 A though the fully irsuIated plug I-ontacts on the moduie's output cables provide touc,-safe protection, you must observe the following points when handling the modules,in order to avoid the risk of sc,arking, fire hazard,burn risk,and lethal electric shocks. • Exercise extreme caution when wiring the modules and look out For damaged cable ends,split cable ends,dirt,etc. • Never insert metallic or otherwise conductive objects into the plugs or sockets. • Ensure that all electrical connections are completely dry before they are assembled. • Keep all materals,tools and working conditions clean and dry. • Always use appropriate safety equipment such as insulated tools and insulated gloves. MECHANICAL INSTALLATION Caution:Only qualified personnel should perform work on PVsystems,such as Installation, commissioning,maintenance and repairs.Be sure to follow the safety instructions for all system components It is also important to observe relevant local codes and regulations for health and safety and accident prevention. A)FIRE GUIDELINES Utilize the following fare safety guidelines when installing REC.PE series t-ncdules: • REC PE Series modules~ave a Class C Fire eating. • Check with local authorities for guidelines and requirements concerning 5(e safety For any building or structure that the modules will be mounted on or attached to. • The system design should ensure that fire 5ghting personnel can access the system in the event of a building fire.Check with local authorities for any applicable regulations concerning setbacks or other placement restrictions that•may apply for roof-mounted PV arrays. • We recommend that you use DC Ground Fault Interrupters.This may also be required by local and national codes. • All electrical appliances are subject to fire risk.The module should there'ore be mounted over a 5re retardant roof cpverng rated for the application and the minimum distance to the roof top should be 4 inches(10 cm). B)ORIENTATION To maximize system output,install the modules at optimum or entation and t1 t angles.The speci5cs of this depend on the location and must be calculated by a qualified s/stem designer The ideal angle for mounting the module should result in the sun's rays failing perpendicular(i.e at a 90'angle)to the moduie surface.In each series strung,all the modules should have the same orientation and tilt.This will ensure that they do not under-perform,as a result of mismatching of each module's outputs. The modules should not be exposed to artificially concentrated light. Evenminor or partum shading or ihe,,odules,>array will reduce array,'system output.A module is considered shade-*"ree when it is both: • Free from shade or shadows ail year round. • Exposed to 7everai`ours of direct sunlight,even during shcoest days or the year t C)ENVIRONMENTAL FACTORS The nodules are designed to be installed in moderate/temperate 0 atic_onditions. T he!modules are not suitable for installation in potentially hazardous,locations The rr?odOes should not be lnstailed at the fioilowing lom-ations: • Near sources of Flammable gases and vapors,such,.as gas/petr of stations,gas storage�ortalners,sor ay paint facilities. • dear open flames. • Underwater or in a fountain or other similar water Feature. • Where they are exposed to salt.Recommended distance From;,the sea'600 Feer(500 n, • Where they are exposed ro sulfur,such as near sulfur springs or volcanoes,because of the danger of corrosion. • 'Where they can be exposed to coreosive chemicals. D)MODULE HANDLING Modules should be handled with care,and the warnings and instructions on their packaging should be observed.Follow these guidelines when unpacking,transportfng or storing the modules: • Record the module serial numbers before ns'allation and note the;nfcrmation,in the system documentation. • Carry the modules using both`!ands and avoid using the junction box as a grip. • Do not allow the modules to sag or bow under their own weight when being carried. • Do not subject the modules to loads or stresses-and avoid stepping on or dropping them_ • Keep all electrical contacts clear and dry. • if you need to store modules temporarily,keep them mn a dry,properly ventilated room. • Do not apply any forces to the backsheet. Note that if the module front glass is broken or laminate back sheet damaged,it can expose personnel to hazardous voltages.There ore: • If you must mark-nodules,avoid using sharp or pointed objects • Never apply paints,adhesives,or detergents to the back of the iaminate. • Do not use ary solar:module that is damaged or has iOpen.tampered-wirh. • Never attempt to disassemble the modules. E)MOUNTING REC PE Series modules are designed strictly far capturng solar r adiation and are nor suitable For instaila}ion as overhead or vertical glazing. The distance between the mo&es.and i-he irstailauocn surface must be at'`:eas`iu cm to ensure adequate cooling.

Site-specific loads such as wind and snow need to be taken into consideration to ensure that this weight loading is not exceeded. The modules are built to withstand a downward force no greater than 551 Kg/m2(5400 Pa)with long-side mounting,no greater than 245 Kg/m2(2400 Pa)with short-side mounting(fig 4). Site-specific loads such as wind or snow need to be taken into consideration to ensure that this limit is not exceeded. NOTE.In areas of snow build-up modules can be subjected to forces in excess of the stated limit even when snow depth does not appear extreme,thus causing damage to the framework. If the installation is likely to be affected by this,further suitable module support is recommended on the lower row of modules. ARRAY r; r : n Fastening the modules to the mounting structure Each module must be securely fixed to the mounting structure at a minimum of four points.

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 for more clarification on the use of Method I.Lower design by the American Society of Civil Engineers and referenced in wind loads may be obtained by applying Method II from ASCE the International Building Code 2006. For purposes of this 7-05.Consult with a licensed engineer if you want to use document,the values,equations and procedures used in this Method II procedures. document reference ASCE 7-05,Minimum Design Loads for The equation for determining the Design Wind Load for Buildings and Other Structures. Please refer to ASCE 7-05 if components and cladding is: 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 Pnet(PSD =AKzt7 pnet3o pressures on components and cladding in this document. pnet(p�s =Design Wind Load The method described in this document is valid for flush,no tilt,SolarMount Series applications on either roofs or walls. A=adjustmentfactorfor height and exposure category Flush is defined as panels parallel to the surface(or with no more than 3"difference between ends of assembly)with no Kzt=Topographic Factor at mean roof height h(ft) more than 10"space between the roof surface,and the bottom I=Importance Factor of the PV panels. This method is not approved for open structure calculations. pnet30(psf) =net design wind pressure for Exposure B,at height Applications of these procedures is subject to the following _30 I= I 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 You will also need to know the following information: on structures greater than 60 feet,contact your local Unirac Distributor. Basic Wind Speed=V(mph),the largest 3 second gust of wind in 2.The building must be enclosed,not an open or partially the last 50 years. enclosed structure,for example a carport. h(ft) =total roof height for flat roof buildings or mean roof 3.The building is regular shaped with no unusual geometrical height for pitched roof buildings irregularity in spatial form,for example a geodesic dome. Roof pitch(degrees) 4.The building is not in an extreme geographic location such as a narrow canyon or steep cliff. This manual will help you determine: 5.The building has a flat or gable roof with a pitch less than 45 Effective Wind Area(sf)=minimum total continuous area of degrees or a hip roof with a pitch less than 27 degrees. modules being installed(Step 2) 6.If your installation does not conform to these requirements please contact your local Unirac distributor or a local Roof Zone=the area of the roof you are installing the pv system professional engineer. according to Step 3.

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 than one footing on both sides of the splice.(Reference installation manual 908,Splices/Expansion Joints.) Figure 13.Splice bars slide into the footing bolt If using more than one splice per rail,contact Unirac concerning slots of SolarMount rail sections. thermal expansion issues. Mounting Rails on Footings:Rails may be attached to either of two mounting holes in the L-feet(Fig. 14). Mount in the lower hole for a low profile,more aesthetically pleasing installation. Mount in the upper hole Clamping for a higher profile,which will maximize airflow under the modules. This bolt slot will cool them more and may enhance performance in hotter climates. Slide the'/a-inch mounting bolts into the footing bolt slots. Loosely attach Mounting the rails to the footings with the flange nuts. slots Ensure that the rails are oriented to the footings as shown in Figure 8,9, Footing 11,or 12,whichever is appropriate. bolt slot 4 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 Figure 14.Foot-to-rail splice attachment 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 parallel to the rafters(Fig.16),the aligned end of 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 rails within a few hours if module placement is delayed.

If modules have standard J-boxes,each module should be r� 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.
