If you have any questions about installation and the Warranty validity,please contact REC's technical support. ELECTRICAL INSTALLATION ELECTRICAL REQUIREMENTS i) Application Class REC modules are rated for use in electrical application class A:Hazardous voltage(IEC 61730:higher than 50V DC;EN 61730:higher than 120V),hazardous power applications(higher than 240W)where general contact access is anticipated(modules qualified for safety through EN IEC 61730-1 and-2 within this application class are considered to meet the requirements for Safety Class II). ii) System Requirements REC modules are only for use where they meet the specific technical requirements of the complete system. Ensure other components will not cause mechanical or electrical damage to the modules. Only modules of the same type and power class should be connected. iii) String configuration When using string configuration,plan and execute it according to inverter manufacturer's instructions. The number of modules connected to an inverter must 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 1000V. Maximum system fuse rating is 25A,maximum reverse current is 25A. iv) String connection Modules connected in series must have the same amp rating. The maximum number of modules that can be connected in series depends upon system design,type of inverter and environmental conditions. There are no restrictions on the number of modules that may be connected in parallel. Module configuration must correspond to the specifications of other system components e.g.inverter. Refer to the reverse current rating of the module(indicated in the Technical Characteristics on p.11 or on the module datasheet). v) Wiring layout To minimize voltage surges(e.g.indirect lightning strikes),cables of the same string must be bundled together so loops are as small as possible. String configurations must be checked before commissioning. If open circuit voltage(V,,)and short circuit current(I )deviate from specification,this may indicate a configuration fault. Correct DC polarity is to be observed at all times. vi) Junction box,cables,connectors and materials The junction box on REC Peak Energy modules 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 outdoor use must be used. Conductor gauge must be chosen to ensure DC power losses(voltage drop)are kept to a minimum(<1%). Observe all local regulations when selecting cables. For field connections,use minimum 4 mm'or copper wires insulated for a maximum operating temperature of 90°C. Secure cables using UV- resistant cable ties or other sunlight-resistant device. Loose and unsecured cables must be protected from damage(e.g.mechanical, abrasion,sharp objects,animals). Avoid exposing cables to direct sunlight and permanent tension. viii) Electrical Ratings Electrical ratings(pl0)are within 3%of measured values at Standard Test Conditions(STC). When designing a system,allow for increased output of a module as a result of conditions different to STC by multiplying the values of Is,and V( by 1.25%(or according to the respective national regulations for the installation of electrical systems). SAFETY MEASURES All relevant codes and regulations should be referred to and observed as well as regulations on working at heights and fall protection. i) Safety in the working area Installation of REC Peak Energy modules may involve rooftop work. Ensure all local regulations regarding working at heights are followed. Before beginning work on a photovoltaic system,ensure all working surfaces are structurally sound and capable of bearing the weight of employees and required equipment. Remember to isolate the system from the grid before carrying out any maintenance or repair work. ii) Preventing current generation 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. iii) Specific hazards of DC electricity Solar modules generate direct current(DC). Once current is flowing,breaking or opening a connection(e.g.disconnecting two modules)can cause an electrical arc. Unlike low voltage AC wiring,DC arcs are not self-extinguishing. They are potentially lethal burn and fire hazards: • Follow module 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 module and modules connected in series(voltages added together)or in parallel(currents added together) can be dangerous. Although the fully insulated plug contacts on the module's output cables provide touch-safe protection,the following points must be observed during handling to avoid the risk of sparking fire hazards,burns and lethal electric shocks. • Excercise extreme caution when wiring modules and look out for 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 modules produce current when exposed to sunlight. Do not connect the system to the inverter during solar exposure. 4 MECHANICAL INSTALLATION FIRE GUIDELINES - REC Peak Energy Series modules have a Class C Fire classification. Utilize the following fire safety guidelines when installing REC Peak Energy Series modules: • Check with local authorities for fire safety guidelines and requirements for any building or structure on to which the modules will be installed. • The system design must 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 apply for 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 module must therefore be mounted over a fire retardant roof covering rated for the application and a suitable distance between the module and the mounting surface,allowing free circulation of air beneath the modules (6-10 cm)should be respected at all times. ORIENTATION To maximize system output,modules 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. Dependent on local conditions,a lower angle of installation will potentially increase the requirement for regular cleaning. The optimal mounting position of modules results in the sun's rays falling perpendicular(i.e.at 90°)to the surface. All modules in a string should,wherever possible,have the same orientation and tilt to ensure the system does not underperform due to mismatched outputs. nThe modules should not be exposed to artificially concentrated light. ENVIRONMENTAL FACTORS REC Peak Energy Series modules are designed to provide decades of durable and stable output. Operating temperatures must be between -40 and+80°C. The modules 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 e.g.gas stations,gas containers or spray paint facilities. • • Near open flames. • Under water or in water features. • Where exposed to sulfur e.g.near sulfur springs or volcanoes. • • Where the modules may be exposed to harmful chemicals. AEnsure modules are not exposed to direct contact with salt water/spray and avoid installation in areas subject to high salt mist content. MODULE HANDLING Modules should be handled with care and protected from damage at all times. All warnings and instructions on the packaging should be observed. Follow these guidelines when unpacking,transporting or storing the modules: • Record the serial numbers prior to installation and note the information in the system documentation. • Carry the modules using both hands and do not use 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. • Do not stand on the modules. • Avoid dropping the modules as any damage caused may be unseen. • Keep all electrical contacts clean and dry. • Store modules in a dry and properly ventilated room. • Do not apply force to the backsheet. • Avoid using sharp or pointed objects if modules require marking. • Never apply paints,adhesives or detergents to the back of the laminate. • Do not use any solar module that is damaged or been tampered with. • Never attempt to disassemble,modify or adapt the modules or labels in any way as this will void the warranty. ADo not use a module which is broken or damaged. If the module front glass is broken or laminate back sheet is damaged,it can expose personnel to hazardous voltages. MOUNTING THE MODULES REC Peak Energy Series modules are designed for capturing solar radiation and are not suitable for installation as overhead or vertical glazing. The junction box on the rear of the module is protected to IP67 and hence modules can be mounted in any orientation. The modules must be installed so that no part of the cells is shaded as this will drastically reduce electrical output. If partial shading is inevitable at certain times of the day or year,it must be kept to an absolute minimum. REC Peak Energy modules are typically installed on a rail-based mounting system. There are three different methods of installing an REC Peak Energy module,depending on the design load of the array. The rails can run under the frame or parallel to the frame,directly under the clamping zones(fig 1). Ensure the mounting structure is able to withstand anticipated wind and snow loads. Mounting hardware is not supplied by REC-see specifications below. Follow manufacturer's instructions and recommendations at all times. Fig.1:Rail positioning options: Nbki *1%1 06,101So. --41114 (a)rails parrallel to (b)rails across the module mounting side / mounting directions AEnsure a distance of between 6-10 cm between the uppermost part of the roof and the lowest part of the module to ensure sufficient airflow beneath the modules and adequate cooling of the modules. i) Rail specifications The clamps should be fastened to C or H channel rails suitable for the safety class of the modules(fig.2). • Minimum thickness of walls for mechanical connections of 4.0 mm • Minumum thickness of walls exposed to buckling load of 2.0 mm • Moment of Inertia for profile area about X-X:min array mounting diagram in 19.2 cm' Fig.2:Rail specification AN Walls for mechanical connectors X • Walls exposed to buckling load C channel rail rI channel rail The overlap between the support rail and the outer edge of the module frame must be a minimum of 6 mm. ii) Clamp Specification Ensure the clamps have a minimum yield strength of 200 MPa and a minimum tensile strength of 190 MPa.(fig.3). • The module must be clamped by a minimum of two clamps per side(four clamping points per module)(fig 4). • Minimum required grip length of 40 mm,minimum grip depth of 5 mm. The grip must not overlap the module frame and cause shading. • A minimum thickness of load carrying walls of 2.5 mm. Use approproate bolted connections as per manufacturer's instructions. • Follow the clamp manufacturer's recommended applied torque to fasten the clamps. Fig.3:Clamp specifications Fig.4:An array mounting system with each module secured at four points. Minimum grip Minimum grip length 40 mm length 40 mm Minimum grip depth Minimum grip '„, '� 5 mm mi Minimum thickness of depth 5 mm load carrying walls 2.5 mm AIn 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,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. iii) Clamp mounting positions The modules can be fixed on both the long and the short side of the module within the constraints shown in fig.6. The modules are built to withstand a downward force of up to 5400 Pa(550 kg/m2)or 2400 Pa(240 kg/m2)according to where they are clamped. Site-specific loads such as wind or snow which may exert forces in a different way need to be taken into consideration to ensure this limit is not exceeded for each respective mounting option. I I Clamping within the yellow zone(0-208 mm long side,250 mm short side)is certifed for design loads up to 2400 Pa(244 kg/m2) Clampingwithin the green zone(208-416 mm)is certified for design loads up to 5400 Pa(550 kg/m2) Clampingwithin the red zone is not permitted(>416 mm long side,>250 mm short side).

E E E rn Kw r V ♦ I E E 111111111111111111111 N N O D 0 t0 If two or more clamping zones are used,the module is certified to the lower value only. iv) Mounting holes The modules can also be secured to the mounting structure using the mounting holes(fig.6)found on the underside of the frame(6.6 x 1]. mm,spaced 450 mm from the midpoint of the long side). The frame must be supported by two transverse rails(fig.1 page 6). Bolts of size 6 mm secured with 6 mm locking nuts with a flange should be used to secure the frame to the mounting structure. Observe the following procedures when using mounting holes: • The mounting construction should be of aluminium or galvanized steel to avoid galvanic corrosion and be appropriate for the local environment. • Additional electrical bonding to Ground is required for the support structure(see p.8). • All four mounting holes in the frame must be used. • Tighten fastenings using a torque wrench according to the understructure manufacturer's instructions. AThe module warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be corrosion resistant. 44/ Fig.6: Mounting holes Fig.7: Mounting using mounting holes 4'b Mounting holes ..... • v) Slide-in Systems REC Peak Energy modules may also be installed using slide-in systems. Such mounting systems must meet the same specifications regarding grip lengths and depths as clamps and be able to withstand the correct load pressures. When installing with slide-in systems,the drainage holes(fig.8)must not be covered. For any questions regarding installation on such systems,please contact REC directly. vi) Drainage holes Each corner of the module frame has small drainage holes(fig.8)to allow water caused by rain or snow melt to exit the frame easily and to minimize damage caused by freezing and thawing. These must not be used for mounting the module. A\\ Ensure the drainage holes are not covered by the mounting structure.

Check all applicable requirements before beginning installation. Where grounding is necessary,it must be done using an electrical connection from the module frame: • Suitable grounding lugs must be used. • Grounding cable size should be between 2.1 mm2-21.2 mm2. • Attach grounds to the grounding holes in the module frames. • Fix lug to the frame using a star washer and lock nut,ensuring a conductive connection(fig.9). • Place the star washer between the frame and the nut,using an M10 stainless steel bolt and locking nut to mount the lug to the module frame and tighten according to the manufacturer's recommended torque. To avoid galvanic corrosion,stainless steel fastening materials are preferred,however galvanized or hot dipped zinc plated fasteners are equally suitable. MAINTENANCE CLEANING INSTRUCTIONS REC Peak Energy modules have been designed for easy maintenance. Normal rainfall will naturally clean the modules 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 cleaning will be required. To optimize electrical output it is recommended to clean the modules when dirt can be seen on the glass surface. • Cleaning of the module should be carried out in the early morning when the modules are cool to avoid thermal shock. If dirt remains on the module,it may cause cell shading which will reduce power output or even cause further damage. To clean either the front or rear of the modules,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 module,take care not to scratch the surface or introduce foreign elements that may cause damage. Ensure the water used is free from grit and physical contaminants that may damage the module. Always rinse the module with plenty of water. If soiling remains on the module,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 module,laminate or cells. Using a rubber squeegee,wipe the module surface from the top downwards motion to remove any residual water from the module glass. Modules can be left to dry in the air or wiped dry with a chamois. Avoid putting pressure on the module surface when drying. For more information on cleaning REC modules,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 modules and ground). RECYCLING REC has made every effort to ensure module packaging is kept to a minimum. The paper and cardboard packaging can be recycled and the protective wrapping and module separating blocks are also recyclable in many areas. Recycle according to local guidelines and regulations. REC is a member of PV Cycle-the independent,not-for-profit association managing a fully operational collection and recycling scheme for end-of-life photovoltaic modules throughout Europe.
