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 should be referred to and observed.
SAFETY IN THE WORKING AREA
Installation of REC solar panels may involve working on rooops 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.
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.UnlikelowvoltageACwiring,DCarcs arenotself-extinguishing;theyarepotentiallylethalburn andfirehazards,capableofhightemperatures
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.

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 aempt to disassemble, modify, or adapt the panels or labels in any way as this will void the warranty.
Thepallet packaging isnot water- orweatherproof. Priorto installation,and toavoiddamage or degradationtothe packaging orpanelcomponents,
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  m above sea level. Ambient operating
temperatures must be between -° and +°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 stations, gas containers or spray paint facilities,
• Near open flames,
• Near 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.
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.

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 (>V), current(>A)
and power (>W) where general contact access is anticipated (panels qualified for safety through IEC - and -).
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
Whenconnectingpanelsinastring,planandexecuteaccordingtotheinvertermanufacturer’sinstructions.Thenumberofpanelsconnectedtoaninverter
mustnotexceedthevoltagelimitsandoperatingrangepermiedbythemanufacturer,nor under any circumstanceexceedthemaximumsystemvoltage
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.:foraVsystem,ifthelowestambienttemperatureis°C,thepanelhasaVOC of.Vandatemperaturecoefficient
of VOC of -./°C, the maximum panels per string is  (∆T°C = ° - ° = °; ° x . = .; . + . = .; V / . = ., so a total
of panels or  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 aspecific tolerance of measured values at StandardTest Conditions (STC)as given in thetechnical 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 . (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
REC solar panels have a Class C fire classification. 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  mm between the panel and the mounting surface, to allow the free circulation of air beneath the panels at all times.
ORIENTATION
Theoptimal mounting positionof apanel resultsin thesun’sraysfallingperpendicular (i.e.,at °)to thesurface.To maximizesystemoutput, 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.

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. The IP rating of the junction box provides a level of protection that allows panels to be mounted in any
orientation. 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.

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 le on the glass.

CAUTION
There must be a minimum clearance gap of  mm between the uppermost part of the installation surface (e.g., rooop) 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. The larger the clearance gap the beer air can circulate. The surface below the panels must be kept clear of any objects that may
cause damage to the panel.

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. ) must not be covered.
For any questions regarding installation on such systems, please contact REC directly.
MOUNTING METHODS: MOUNTING HOLES
RECsolarpanelscanbeinstalledutilizingthefourmountingholes(x.mm)ontheundersideofthepanelatadistanceof.mmfromthecorner(fig.)
in conjunction with a device, e.g., screws, lockbolts or structural blind fasteners, with specifications suitable for the installation (fig. ).
InstallingRECsolarpanelsusingthemountingholeshasbeenfoundtocomplywithIEC& IECrequirementsfor downward pressure,e.g.,
snow, of up to  Pa ( Pa design load*) and upward pressure,e.g., wind, of up to  Pa ( Pa design load*) according to the following
instructions (*design loads apply a safety factor of . to the stated test load, e.g., test load  Pa / . =  Pa design load).
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. ),
• Additional electrical bonding to Ground is required for the support structure,
• Refer to the fixing device manufacturer’s installation instructions for preload or torque values.

DRAINAGE HOLES
In each corner of the REC frame small drainage holes are spaced  mm from the corner on long and short sides (fig. ). These allow humidity
caused by rain, condensation, snow melt, cleaning or any other process to exit the frame easily and minimize damage.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 aer installation. The shape and dimensions of
the drainage holes may vary depending on product and/or frame design.
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.  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,
• Aach 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,
• Wherecommongroundinghardware(nuts,bolts,starwashers,split-ringlockwashers,flatwashersandthelike)areusedtoaachagrounding

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 (<).
Observe all local regulations when selecting cables.
• For string connections, use minimum  mm2or copper wires insulated for a maximum operating temperature of °C,
• Avoid exposing cables to direct sunlight and permanent tension.
Inorderto ensuredurableandsafeconnections between panels andBOS equipment,the followinginstructionsmust befollowedin orderto protect
the electrical connections from the elements.
CONNECTORS
To ensure connector compatibility and reduce the potential for damage to the panels and the wider installation, the connectors used on the REC solar
panels are detailed in the Panel Characteristics at the rear of this manual. REC only permits the mating of factory-installed connectors to connectors
of the same manufacturer, type, and system rating as shown in the table below (fig. ):
Fig. : Connector mating matrix
Connector  +Connector  Permied?
REC Factory-Installed + REC Factory-Installed 
REC Factory-Installed + Stäubli MC 
REC Factory-Installed + Any other connector 
CUTTING THE CABLES
The cuing of cables is only permied 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  or UL ) to ensure they are fit for purpose and safety.
• Useof anychemicals orlubricantson theconnectorsor contactsmay onlybe carried outinline withtheconnector manufacturer’sinstructions.
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,
• The cables must have a minimum bending radius of  mm to avoid damage to the insulation (fig. ),
• 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)
NOTE
Some countriesand/or regionshavespecific regulations regardingthe matingof connectors.Installers areresponsible for ensuringthe compliancyof the
system with such local regulations.
i
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.

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.
Using a so 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
le to dry in the air or wiped dry with a clean and so 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.  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. :WEEE symbol
The European WEEE (Waste Electrical and Electronic Equipment) Directive regulates the correct recycling of electronic and electrical waste in all
memberstates ofthe EuropeanUnion (EU).Forend-customers itis afree of chargedisposal system,financed by themanufacturersand 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.
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 permied as these may damage the panels, laminate or cells.
NOTE
• Avoid puing 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 so
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  may be used. Acidic or alkaline detergent may
not be used.
