SAFETY MEASURES
Installers are responsible for the safe and effective installation and operation of the system and for adhering to all applicable local and national standards and regulations. All relevant local codes and regulations must be referred to and observed.
DANGER – Electrical shock
Solar panels generate direct current (DC). Once current is flowing, breaking a connection (e.g., disconnecting two panels) 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: · Isolate the system and remove/open the inverter AC fuse/circuit breaker from the grid before carrying out any maintenance or repair work. · Follow inverter manufacturer’s installation, handling and operating instructions. · High-voltage components need sufficient time to discharge. Wait for the time specified by the manufacturer before commencing work. · Do not use a panel which is broken or damaged. If the panel front glass is broken or laminate back sheet is damaged, it can expose personnel
to hazardous voltages.
SAFETY IN THE WORKING AREA Installation of REC solar panels may involve working on rooftops or raised platforms. Ensure all local regulations regarding working at heights and fall protection are followed. Before beginning work on an installation, ensure all working surfaces are structurally sound and capable of bearing the weight of employees and required equipment.
Preventing current generation To prevent the panels automatically generating current (electricity) when exposed to light, shield the system with a non- transparent cover during installation, maintenance or repair work.
Specific hazards of DC electricity The voltage produced by a single panel, 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 handling to avoid the risk of sparking, fire hazards, burns and lethal electric shocks:
· Exercise extreme caution when wiring panels 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., non-slip 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.

PANEL HANDLING
In order to avoid damage, all REC solar panels 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, carrying, installing or storing panels:
· Record the serial numbers prior to installation and note the information in the system documentation, · Carry the panels using both hands and do not use the junction box or cables as a grip, · Do not allow the panels to sag or bow under their own weight when being carried, · Do not subject panels to loads or stresses, e.g., leaning on them or through the placing of weight on them, · Do not stand or walk on the panels, · Avoid dropping the panels as any damage caused may be unseen, · Keep all electrical contacts clean and dry, · 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 front or rear of the panel, · Do not use any solar panel that is damaged or has been tampered with, · Never attempt to disassemble, modify, or adapt the panels or labels in any way as this will void the warranty.
i NOTE
Use clean and protective gloves when handling the panel as this will avoid the transfer of any fingerprints or soiling to the highly-sensitive and anti- reflective glass surface, ensuring improved light transmission and avoiding any contamination.
The pallet packaging is not water- or weatherproof. Prior to installation, and to avoid damage or degradation to the packaging or panel components, pallets and panels must be stored in a controlled environment, ideally internal, where it is protected from the elements, e.g., rain, dust, and direct sunlight. If overnight storage in an uncontrolled environment is unavoidable, the panels and the pallet packaging must be protected from direct exposure to the elements and from contact with the ground, including earth, mud etc.
CHOOSING AN INSTALLATION LOCATION
REC solar panels are designed to provide decades of durable and stable output in installations up to 2000 m above sea level. Ambient operating temperatures must be between -40° and +85°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 gas or vapor e.g., gas containers or spray paint facilities, · Near open flames, · Where the panels are exposed to direct contact with salt water/spray, · Under water or in water features, · Where exposed to sulfur e.g., near sulfur springs or volcanoes, · Where exposed to artificially concentrated sunlight, · Where the panels may be exposed to harmful chemicals.
i NOTE
For further information regarding installations on water platforms, e.g., floating pontoons, see Annex 1 at the rear of this manual.

ELECTRICAL INSTALLATION
DANGER – Electrical shock
Safety is paramount when working on the electrical installation. Always follow the electrical requirements to avoid the risk of sparking, fire hazards, burns and lethal electric shocks.
ELECTRICAL REQUIREMENTS
Application Class REC solar panels are rated for use in electrical Application Class A, Protection Safety Class II; at hazardous levels of voltage (>35V), current(>8A) and power (>240W) where general contact access is anticipated (panels qualified for safety through IEC 61730-1 and -2).
System Requirements REC solar panels 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 panels. Only panels of the same type and power class should be connected.
String configuration When connecting panels in a string, plan and execute according to the inverter manufacturer’s instructions. The number of panels connected to an inverter must not exceed the voltage limits and operating range permitted by the manufacturer, nor under any circumstance exceed the maximum system voltage as stated in the technical specifications for the product at the rear of this manual. The maximum system fuse rating (overcurrent protection rating) and the maximum reverse current for each panel can be found in the technical specifications for the product at the rear of this manual. The maximum number of panels in a string can be calculated by dividing the maximum system voltage of the panel by its VOC accounting for the lowest ambienttemperatureatsite,e.g.:fora1000Vsystem,ifthelowestambienttemperatureis15°C,thepanelhasaVOC of40.8Vandatemperaturecoefficient of VOC of -0.27%/°C, the maximum panels per string is 23 (T°C = 25° – 15° = 10°; 10° x 0.27 = 2.7%; 40.8 + 2.7% = 41.9; 1000 V / 40.4 = 23.9, so a total of 23 panels or 974 V). Qualified system designers can make exact calculations that account for specific project requirements and site conditions.
String connection Panels connected in series must have the same ampere rating. The maximum number of panels that can be connected in series or parallel depends upon system design, inverter type and environmental conditions. String configuration must correspond to the specifications of other system components e.g., inverter. Refer to the reverse current rating of the panel indicated in the technical characteristics at the rear of this manual or on the panel datasheet.
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 (Voc) and short circuit current (Isc) deviate from specification, this may indicate a configuration fault. Correct DC polarity must be observed at all times.
Electrical Ratings Electrical ratings are within a specific tolerance of measured values at Standard Test Conditions (STC) as given in the technical characteristics for each panel at the rear of this manual. Allow for increased panel output as a result of conditions different to STC by multiplying the ISC and VOC values by a factor of 1.25 (or according to local regulations) when determining component voltage ratings, conductor ampacities, overcurrent device ratings and size of controls connected to the PV output.
MECHANICAL INSTALLATION
FIRE GUIDELINES The REC solar panels covered by this manual have a Class C (referencing UL 790) fire classification. The REC solar panels in 60- and 66-cell format are rated Type 2 fire classification according to IEC 61730-2:2016 (ref. ANSI/UL 1703). Utilize the following fire safety guidelines when installing REC solar panels:
· Check with all relevant local authorities for fire safety requirements for any building or structure on to which the panels will be installed, · The system design must ensure that it can be easily accessed in the event of a building fire, · Check with relevant 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 panel must be mounted over a fire retardant roof covering rated for the application and a distance
of at least 20 mm between the panel and the mounting surface, to allow the free circulation of air beneath the panels at all times.
ORIENTATION The optimal mounting position of a panel results in the sun’s rays falling perpendicular (i.e., at 90°) to the surface. 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. All panels in a string should, wherever possible, have the same orientation and tilt to ensure the system does not underperform due to mismatched outputs. Dependent on local conditions, a lower angle of installation will potentially increase the requirement for regular cleaning.
i NOTE
The IP rating of the junction box provides a level of protection that allows panels to be mounted in any orientation.

PANEL INSTALLATION
REC solar panels are designed for capturing solar radiation and can be installed where they conform to all local structural regulations. If installing REC solar panels in overhead or vertical constructions, the installer must ensure that all local building codes and regulations specific to such installations are correctly followed. There are different options for securing REC solar panels depending on the design of the array. Mounting hardware is not supplied by REC. Ensure the mounting structure can withstand anticipated wind and snow loads. Follow the mounting hardware manufacturer’s instructions and recommendations at all times.
i NOTE
Panels must be installed so that the cells are not 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. Remove any labels or stickers that may be on the front of the panels and ensure no residue is left on the glass.

CAUTION
There must be a minimum clearance gap between the uppermost part of the installation surface (e.g., rooftop) and the lowest part of the panel (i.e., underside of panel frame) to avoid any damage to the panel and to ensure sufficient airflow for cooling, helping to improve performance.
Minimum clearance gap 60-cell format REC solar panels: 20 mm BILD EINFÜGEN The surface below the panels must be kept clear of any objects that may cause damage to the panel.

SECURING OF PANELS A typical installation of solar panels will be carried out with suitable rails and clamps. Other types of panel support, e.g., plates, must meet the same specifications. Such installations have been found to be in compliance with IEC 61215 & IEC 61730 requirements for the maximum stated test loads which can be found for each individual panel type in the Panel Characteristics section at the end of this manual. Site-specific factors such as high wind or snow levels must be taken into consideration to ensure this limit is not exceeded.

When installing on mounting rails, ensure they run underneath the panel and provide support to the frame. The positioning of the rail must ensure that the minimum clamp grip length (fig. 1) and the central point of the fixation, e.g., the bolt, is fully within the required clamping zone as indicated on the following pages.
REC modules must be secured with a torque as shown in the table below (fig. 1). Clamp installation must be carried out according to the manufacturer’s instructions, including specific hardware and torque requirements. Ensure the clamps used are suitable for the planned installation and expected system design loads.
· The grip area must not extend onto the panel glass and/or cause cell shading,
· Avoid the application of excessive pressure to prevent frame deformation,
· The panel must be secured, e.g., clamped, at least once in each of the four marked zones shown below (fig. 2).

i NOTE
· 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, potentially causing damage to the panel. If the installation may be affected by this, further panel support is recommended, especially on the lower row of panels.
· In the case of any questions regarding mounting systems, or if the mounting system to be used does not match any of the instructions shown in this installation manual, please contact REC for further support.

Once a module is secured in each of the 4 zones (fig. 2), additional clamps, i.e., 5, may be freely located on panel frame without
affecting the warranty. Loads marked with a * were not certified as part of IEC 61215/61730 testing; these have been evaluated by REC’s internal testing process.

CAUTION
The center point of each clamp and the minimum grip length must be fully located in the same clamping zones to be rated to that load (fig. 4). If the panel is secured in zones with different load values, it is rated to the lowest load value only.

MOUNTING METHODS: SLIDE IN SYSTEMS When installing using slide in systems the mounting system must meet the same specifications including grip lengths, depths and spacing as specified for clamping and the mounting system must be able to withstand the correct load pressures.
When installing solar panels using a slide-in system, the drainage holes found in the underside of the panel frame (see fig. 16) must not be covered. For any questions regarding installation on such systems, please contact REC directly.
MOUNTING METHODS: MOUNTING HOLES The REC solar panels covered by this manual can be installed utilizing the four mounting holes (11 x 6.6 mm) on the underside of the panel (fig. 12 ) in conjunction with a device, e.g., screws, lockbolts or structural blind fasteners, with specifications suitable for the installation (fig. 14).
Installing REC solar panels using the mounting holes has been found to comply with IEC 61215 & IEC 61730 requirements for downward pressure,e.g., snow, of up to 7000 Pa (4666 Pa design load) and upward pressure,e.g., wind, of up to 4000 Pa (2666 Pa design load) according to the following instructions (*design loads apply a safety factor of 1.5 to the stated test load, e.g., test load 5400 Pa / 1.5 = 3600 Pa design load).

CAUTION
The product warranty will be voided if additional holes are made in the frame. All fixing and fastening materials must be corrosion resistant.

455 [17.9] When installing using mounting holes, the frame and panel edge of each panel must be supported by two rails of aluminium or galvanized steel suitable for the application and appropriate for the local environment. Observe the following procedures when using mounting holes:
· The mounting construction must be of a corrosion resistant material, e.g., aluminum or galvanized steel, and appropriate for the local environment,
· All four mounting holes in the frame must be used (fig. 15), · A washer must be used between frame and rail, · Additional electrical bonding to Ground is required for the support structure, · REC modules must be secured with a torque between 12 – 25 Nm. Refer to the fixing device manufacturer’s installation instructions for
preload or torque values.

MOUNTING METHODS: SIX-POINT MOUNTING
A six-point mounting configuration secures the panel on three continuous rails (or other support structures) with three clamps on each side of the panel in the zones marked below: This helps to increase the downward load a panel can withstand, e.g., snow. The third clamp is typically installed in the central area of the panel as shown in Fig. 18:

CAUTION
· The middle rail must not be installed on the side of the junction box where the cables exit. · A total of three continuous rails (or other support structures) must be used to secure the panel. · The center point of each clamp and the minimum grip length must be fully located within the marked zone to be rated to the given value
(fig. 27).

DRAINAGE HOLES On the long and short sides of the REC frame small drainage holes can be found that allow humidity and water to exit the frame easily and minimize damage (fig. 18). These are spaced 55 mm from the corner. These holes must not be used for mounting the panel, and they must not be covered by any part of the mounting structure. To enable effective drainage and ensure there is no damage to the panel, the drainage holes must remain fully open and enable water egress during and after installation. The shape and dimensions of the drainage holes may vary depending on product and/ or frame design.

Fig. 19: Drainage and grounding holes

Drainage holes

GR

Grounding holes

GROUNDING
Local regulations may require grounding of the panels. Grounding must be done using an electrical connection from the panel frame. REC solar panels have a small round grounding hole positioned near each corner of the panel on both the long side and the short side, as shown in fig. 18 and can be further identified by the grounding symbol stamped in the frame next to it. Check all applicable requirements before beginning installation:
· Suitable grounding clips, lugs or other constructions must be used, · Attach grounds to the grounding holes in the panel frames, · Follow the grounding device manufacturer’s installation instructions to ensure a safe and conductive connection, including any
supplementary hardware, e.g., star washer, and tighten according to recommended torque, · Where common grounding hardware (nuts, bolts, star washers, split-ring lock washers, flat washers and the like) are used to attach a grounding
device, the attachment must be made in conformance with the grounding device manufacturer’s instructions.
i NOTE
· To avoid galvanic corrosion, galvanized or hot dipped zinc plated fasteners are preferred, however stainless steel fastening materials are equally suitable.
· The support bars across the rear of REC panels are connected to the frame via specially designed grounding clips and do not need to be individually grounded.
· Negative grounding of the panels is not required by REC.

CONNECTIONS AND CONNECTORS
The connector type(s) used on REC panels are indicated in the product specifications at the rear of this manual. The connector IP rating is only valid when correctly connected. 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 string connections, use minimum 4 mm2 copper wires insulated for a maximum operating temperature of 90°C, · Avoid exposing cables to direct sunlight and permanent tension. In order to ensure a safe connection between panels and BOS equipment, the following instructions must be followed to protect the connections from the elements.
DANGER – Electrical shock
Safety is paramount when working with electrical connectors. · Ensure that any installation work is not carried out on live or load-carrying parts. · Connections must not be disconnected under load and the system must be isolated from the grid before carrying out any maintenance or repair work.
CONNECTORS To ensure connector compatibility and reduce the potential for damage to the panels and the wider installation, the connectors used on REC panels are detailed in the Panel Characteristics at the rear of this manual. REC only permits the mating of connectors of the same manufacturer, type, and system rating.
i NOTE
Some countries and/or regions have specific regulations regarding the mating of connectors. Installers are responsible for ensuring the compliancy of the system with such local regulations.
CUTTING THE CABLES The cutting of cables is only permitted in order to replace a factory-installed connector with another brand of connector to ensure `like- for-like’ mating when connected to a non-REC external device. All other changes are prohibited and will invalidate the REC warranty.
· The connector replacement procedure must be carried out correctly and according to the replacement connector manufacturer’s instructions. · The selected replacement connector must also fulfil all relevant technical specifications and be certified according to applicable standards (e.g., IEC
62852 or UL 6703) to ensure they are fit for purpose and safety. · Use of any chemicals or lubricants on the connectors or contacts may only be carried out in line with the connector manufacturer’s instructions. The REC warranty does not extend to cover any fault traceable to the replaced connectors. Any other modification to the panel is prohibited, including the opening of the junction box, unless explicitly authorized by REC. Doing so will invalidate the warranty.
CABLE MANAGEMENT
To ensure a long life span of the cables and reduce the potential for damage to the cables, follow the instructions below: · To prevent stress on the junction box casing, ensure the cable exits the junction box in a straight line before any bend in the cable and ensure cables are free from any external load, · The cables must have a minimum bending radius of 30 mm to avoid damage to the insulation (fig. 17), · Ensure cables do not hang loose where they may be damaged through friction or stress, e.g., caused by mechanical abrasion or grazing animals, · Protect connectors from falling or dropping water by locating them directly beneath a panel, · Cables must be firmly secured to the structure, without over-tightening, as this can deform the cable insulation using UV-resistant cables, · When securing the connector, place it so that it has with sufficient air circulation all around. This allows the connector to dry effectively and avoids the risk of damage or degradation of the connection, · Secure the cable either side of the connectors to ensure no stress is exerted on the connector casing or cable entry, · To enable correct cooling and drying of the connectors, do not add extra protection to the connector, e.g., heat shrink, grease or tape.
More detailed information is given in the Guide to Best Practice – Connections and Connectors which can be found via the REC online Download Center (www.recgroup.com/downloads)

PANEL MAINTENANCE
CLEANING INSTRUCTIONS REC solar panels have been designed for easy maintenance. However cleaning solar panels can assist in optimizing electricity output. The need for cleaning will vary dependent on location, rainfall, pollution levels and the angle of installation ­ the lower the angle of installation, the more cleaning will be required. `Normal’ rainfall will naturally clean the panels if installed at a sufficient angle to ensure water runs off the surface. To optimize electrical output it is recommended to clean the panels when dirt can clearly be seen on the glass surface.
CAUTION
· Panel cleaning must always be carried out when the panels are cool, e.g., early morning, to avoid breakage through thermal shock. · Use of high pressure hoses or cleaners is not permitted as these may damage the panels, laminate or cells.
i NOTE
· Avoid putting pressure on the on the panel surface when cleaning or drying, e.g., leaning, standing or resting buckets on it. · Use only deionized water free from grit and physical contaminants, at ambient temperature and use 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. · If stains require more effort to be removed, Isopropyl alcohol of a concentration less than 10% may be used. Acidic or alkaline detergent may
not be used.
Using a soft rubber squeegee, wipe the panel surface from the top downwards to remove any residual water from the panel glass. Take care not to scratch the surface or introduce foreign elements that may cause damage to the panel. Always rinse the panel with plenty of water. Panels can be left to dry in the air or wiped dry with a clean and soft cloth or chamois. For more information on cleaning REC solar panels, consult the REC Cleaning Information Sheet which is available to download from the online REC Download Center www.recgroup.com/downloads. If in doubt at any time when cleaning the panels, stop and obtain professional advice.
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 makes 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. Recycle packaging and panels according to local guidelines and regulations.
DISPOSAL OF OLD ELECTRICAL AND ELECTRONIC EQUIPMENT
Panels should be recycled at the end of their useful life according to local guidelines and regulations. By ensuring REC solar panels are disposed of correctly, you will help prevent potential negative impact on the environment and human health. The majority of the panel components can be recycled. For installations in the European Union, REC solar panels are subject to WEEE regulations. The symbol in fig. 18 as found on the label on the rear of the panel indicates that this product must not be treated as household waste and must be disposed of at an appropriate collection point for the recycling of electrical and electronic equipment. The recycling of the different components and materials will help to conserve natural resources.
Fig. 21: WEEE symbol

The European WEEE (Waste Electrical and Electronic Equipment) Directive regulates the correct recycling of electronic and electrical waste in all member states of the European Union (EU). For end-customers it is a free of charge disposal system, financed by the manufacturers and importers, where panels can be brought to a local recycling depot, or in the case of larger numbers, be picked up from site, as is the case with other electrical equipment, e.g., refrigerators or televisions. The extensive process steps for proper disposal are strictly regulated and place no further obligations on the owner of the panels. For more information about the recycling of this product, please contact your local recycling authority or recycling center.

Ref: PM-IM-20

ANNEX 1: INSTALLATIONS ON WATER PLATFORMS
The REC solar panels covered by this manual may be installed on water platform-type mounting systems (note that the certification testing of solar panels does not include testing on these types of systems). When installing REC solar panels on fixed position (e.g., anchored) water platforms, for example, floating pontoons, follow the instructions below specific to such applications. Failure to do so will invalidate the warranty.
i NOTE
For all installations on water platforms, first advise REC before the start of installation in case of any site specific instructions or constraints.
INSTALLATION ENVIRONMENT
i) Installation site · REC solar panels may only be installed on closed bodies of fresh water where water salinity does not exceed 25 mS/cm at 25°C (15 PSU). This specifically excludes mounting on sea and ocean applications. · The maximum permitted wave height must not exceed 1 m from the crest to the trough of the wave.
ii) Floating platforms · When using a floating platform, follow the manufacturer’s instructions regarding installation, maintenance, inspection and cleaning at all times.
iii) Minimum installation height · The minimum installation height of REC solar panels on floating platform systems is 15 cm and is defined as the height between the water surface and the lowest edge/part of the panel during normal operation. This will help to shield the panel from direct water spray.
INSTALLATION INSTRUCTIONS
i) System installation · All cables used for the installation must have sufficient length and slack to prevent damage due to water level changes and wave motions.
i NOTE
Negative system grounding is required for REC solar panels installed on a floating platform.
ii) Mounting panels · Installation of REC solar panels must be in accordance with the aforementioned standard mounting instructions. · The junction box should be oriented as far as possible from the water surface according to system design and the junction box, cables and connectors must be protected from direct water splash. · The installation must allow for sufficient spacing between individual panels, in order to avoid all contact as caused by the natural movement and flexing of the floating structure.
iii) Panel protection · In areas with high avian activity, additional bird repelling devices may be installed as long as they do not adversely affect system performance, e.g., shading or to the local environment etc. · If using lightning protection equipment on the floating installation, all relevant local regulations must be respected.
MAINTENANCE · Regularly inspect the installation to ensure all panels are securely mounted.
i NOTE
For installations with high avian activity, system cleaning may be required at more frequent intervals to reduce shading of panels caused by bird defecation.
SAFETY · Immediately disconnect the system if the installation or the floating platform exhibits deviation from standard operating conditions. · In the event of the floating platform being submerged, disconnect the DC connection at the inverter immediately. Do not attempt to salvage panels when sunlight is present.

ANNEX 2: INSTALLATIONS USING MODULE LEVEL POWER ELECTRONICS
This section is applicable to all REC products referred to in this installation manual.
Module Level Power Electronics (MLPE) is the name given to the range of panel- level components that can be installed in PV system circuits installed on or in buildings to reduce shock hazard for emergency responders. MLPE devices can be supplied pre-installed by panel manufacturers or as a `retro-fit’ system made by third-party manufacturers.
MLPE devices may be used on REC solar panels where desirable or mandatory (note that the certification testing of solar panels does not include testing with MLPE devices). When installing an MLPE device on an REC solar panel, follow the instructions provided by the device manufacturer and the instructions specific for REC solar panels given below. Failure to follow the manufacturer and the REC instructions may invalidate the warranty.
INSTALLATION
i) Installation · MLPE devices are suitable for use wherever solar panels are suitable for installation. Observe any limitations set by the MLPE manufacturer. (e.g., minimum mounting gap between MLPE and rooftop). · When attaching an MLPE device to a solar panel, it must be secured to the panel frame. Follow MLPE manufacturer instructions to ensure optimum mounting of MLPE device and prevent any slippage during operation. · MLPE devices may also be attached to the mounting construction. In such cases, refer to the instructions provided by the manufacturer. · Wherever possible, the installation of the MLPE device should not cover the product label on the rear of the panel. · MLPE devices may only be installed on REC solar panels in the areas shown in the diagram below (fig. 29 ):
Fig. 29: MLPE device installation zones
Installation of MLPE device in the green zone is permitted. Installation of MLPE device in the red zone is not permitted.

0 – 480 mm [0 – 18.9 in]

GR

0 – 1016mm [0 – 40 in]

CAUTION
· To avoid damage to the panel and to allow for thermal expansion, there must be a minimum gap of 0.1 in (2.5 mm) between the MLPE device and the panel backsheet.
· The mounting holes in the panel frame must not be used for the installation of MLPE devices. · The drilling of extra holes in the frame is not permitted and will invalidate the panel warranty.
CONNECTION
· First ensure the installation of the MLPE device is secure and safe. · Following the device manufacturer’s instructions to connect the cables from the MLPE device to the solar panel correctly (usually positive to
positive [+ to +] and negative to negative [- to -]). · Connection to the next panel in the array should be done from the `free’ cables.
SAFETY · Immediately disconnect the device if there is a problem during installation.
