SAFETY PRECAUTIONS
WARNING:
Before attempting to install, wire, operate and/
or service the module and other electrical equipment, all instructions should be read and understood. PV module interconnectors pass direct current (DC) when exposed to sunlight or other light sources. Contact with electrically active parts of the module, such as terminals, can result in injury or death, irrespective of whether or not the module and the other electrical equipment have been connected.
AVERTISSEMENT:
Toutes les instructions devront être lues et
comprises avant de procéder à l’installation, le câblage, l’exploitation et/ou l’entretien des panneaux.
Les interconnexions des panneaux conduisent du courant continu (CC) lorsque le panneau est exposé à la lumière du soleil ou à d’autres sources lumineuses. Tout contact avec des éléments sous tension du panneau tels que ses bornes de sortie peut entraîner des blessures ou la mort, que le panneau soit connecté ou non.
GENERAL SAFETY
· All Modules must be installed by licensed electricians in accordance to the applicable electrical codes such as, the latest National Electrical Code (USA) or Canadian
Electric Code (Canada) or other national or international electrical codes.
Protective clothing (non-slip gloves, clothes, etc.) must be worn during installation to prevent direct contact with 30 V DC or greater, and to protect your hands against sharp edges.
Use electrically insulated tools to reduce the risk of electric shock.
Prior to installation, remove all metallic jewelry to prevent accidental exposure to live circuits.
If the disconnects and over current protection devices (OCPD‘s) cannot be opened or the inverter cannot be powered down, cover the fronts of the modules in the PV array with an opaque material to stop the production of electricity when installing or working on a module or wiring.
· When installing modules in light rain, morning dew, take
4 | appropriate measures to prevent water ingress into the connector.
· Do not install modules in strong wind.
· Do not use or install damaged modules.
· Contact with module surfaces or frames may cause electric shock if the front glass is broken.
· The PV module does not contain any serviceable parts.
Do not attempt to repair any part of the module.
· Keep the junction box cover closed at all times.
· Do not disassemble a module or remove any module part.
· Do not artificially concentrate sunlight on a module.
· Do not connect or disconnect modules when current from the modules or an external source is present.
· Do not allow children or unauthorized persons near the installation site or module storage area.
may cause cancer, is very toxic to aquatic life, and may cause harm to breast-fed children.
Therefore, recycling and all other types of comparable disassembly of the solar modules have to be performed by a qualified waste management company, in compliance with national and local waste management regulations.
In the instance of fire, please keep away from the fire, and call the local fire brigade.

MECHANICAL / ELECTRICAL SPECIFICATIONS
Module electrical ratings are measured under Standard
Test Conditions (STC) of 1000 W/m 2 irradiance, with an
AM1.5 spectrum, and a cell temperature of 25°C. Detailed electrical and mechanical characteristics of Canadian Solar
Inc. crystalline silicon PV modules can be found in Annex C
(Module Specifications) on www.canadiansolar.com. Main electrical characteristics at STC are also stated on each module label. Please refer to the datasheet or the product nameplate for the maximum system voltage.
2.1 INFORMATION PURSUANT TO ART. 33 OF
THE REACH REGULATION
Pursuant to Art. 33 of Regulation (EC) No 1907/2006 of the
European Parliament and of the Council of 18 December
2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), establishing a
European Chemicals Agency, amending Directive 1999/45/
EC and repealing Council Regulation (EEC) No 793/93 and
Commission Regulation (EC) No 1488/94 as well as Council
Directive 76/769/EEC and Commission Directives 91/155/
EEC, 93/67/EEC, 93/105/EC and 2000/21/EC (the “REACH
Regulation”), we inform you that our solar modules contain a Substance of Very High Concern (“SVHC”) in a concentration above 0.1 % (weight by weight).
Under certain conditions, a module may produce more current or voltage than its Standard Test Conditions rated power. As a result, the module short-circuit current at under STC should be multiplied by 1.25, and a correction factor should be applied to the open-circuit voltage (see
Table 1 below), when determining component ratings and capacities. Depending on your local regulations, an additional 1.25 multiplier for the short-circuit current
(giving a total multiplier of 1.56) may be applicable when sizing conductors and fuses.
The coating of the ribbon of our solar modules contains lead (CAS no. 7439-92-1). Under normal or reasonably foreseeable conditions of use, exposure to the lead that is contained in our solar modules can be excluded. However, a release of, and exposure to, lead can take place (i) when the different components of the solar modules are disassembled, in particular for recycling purposes, and (ii) in instances of fire.
Lead may damage fertility or the unborn child, causes damage to organs through prolonged or repeated exposure, is very toxic to aquatic life with long lasting effects,

4.0 UNPACKING AND STORAGE
PRECAUTIONS
· Module should be stored in a dry and ventilated environment to avoid direct sunlight and moisture. If modules are stored in an uncontrolled environment, the storage time should be less than 3 months and extra precautions should be taken to prevent connectors from being exposed to moisture or sunlight.
· Do not lift modules by their wires or junction box, lift them by the frame.
· Stacks of modules should contain no more than 12 modules, and the frames should be aligned.
· Do not place excessive loads on the module or twist the module frame.
· Unpack module pallets carefully, following the steps shown on the pallet. Unpack, transport and store the modules with care.
· Modules must always be unpacked and installed by two people. Always use both hands when handling modules.
· Do not stand, step, walk and / or jump on modules under any circumstances. Localized heavy loads may cause severe micro-cracks at cell level, which in turn may compromise module reliability and void Canadian Solar
Inc’s warranty.
· Do not carry modules on your head.
6 |
· Do not drop or place objects (such as tools) on the modules.
· Consult your local authority for guidelines and requirements for building or structural fire safety
· Do not use sharp instruments on the modules. Particular care should be taken to avoid module glass being damaged by sharp objects, as scratches may directly affect product safety.
UL 1703 SYSTEM FIRE RATING REQUIREMENTS
· Do not leave modules unsupported or unsecured.
· Do not change the wiring of bypass diodes.
· A photovoltaic systems composed of UL 1703 certified modules mounted on a UL 2703 certified mounting system should be evaluated in combination with roof coverings in accordance with UL 1703 standard, with respect to meeting the same fire classification as the roof assembly.
· Keep all electrical contacts clean and dry at all times.
PRODUCT IDENTIFICATION
· Each module is equipped with three identical barcodes
(one in the laminate under the front glass, the second on the rear side of the module, the third one on the frame) that act as a unique identifier. Each module has a unique serial number containing 14 digits.
· A nameplate is also affixed to the rear of each module.
This nameplate specifies the model type, as well as the main electrical and safety characteristics of the module.
· Mounting systems with a System Fire Class Rating (Class
A, B or C), tested in conjunction with fire rated Type 13 or Type 3 rated modules, are considered acceptable for use with Canadian Solar Inc. modules, provide that the mounting system does not violate any other requirements of this manual.
· Any mounting system limitations on inclination or accessories required to maintain a specific System Fire
Class Rating should be clearly specified in the installation instructions and UL 2703 certification of the mounting system supplier.
5.0
MODULE INSTALLATION
· The fire rating of this module is valid only when mounted in the manner specified in the mechanical mounting instructions.
PRECAUTIONARY MEASURES AND
GENERAL SAFETY
· When installing the modules on rooftop, ensure the assembly is mounted over a fire resistant roof covering rated for the application.
· Prior to installing modules please obtain information about any requirements and necessary approvals for the site, installation and inspection from the relevant authorities.
· Check applicable building codes to ensure that the construction or structure (roof, facade, support, etc.) can bear the module system load.
ENVIRONMENTAL CONDITIONS
· The module is intended for use in general open-air climates, as defined in IEC 60721-2-1: Classification of environmental conditions Part 2-1: Environmental conditions appearing in nature. Temperature and humidity.
· Aluminum frame Dymond solar modules have been qualified for Application Class A (equivalent to Safety
Class II requirements). Modules rated under this class should be used in systems operating at voltage above
50 V or power above 240 W, where general contact access is anticipated.
· Please consult the Canadian Solar Inc. technical support department for more information on the use of modules in special climates.
Do not install modules near open flames or flammable materials.
· Canadian Solar Inc. modules have been certified as Type
13 or Type 3 according to UL 1703 and Class A according to IEC 61730-2, please refer to the datasheet or the product nameplate for the detailed types.
Do not immerse modules in water or constantly expose modules to water (either fresh or salt)
(i.e. from fountains, sea spray).
· Exposing modules to salt (i.e. marine environments) or
EN-Rev IM/GN-ADM-EU/1.1 Copyright © April 2019. Canadian Solar Inc.
sulfur (i.e. sulfur sources, volcanoes) incurs the risk of module corrosion.
· Failure to comply with these instructions will void
Canadian Solar Inc. warranty.
modules is required to allow for thermal expansion of the frames.
| 7
· The small drainage holes on the underside of the module must not be blocked.
INSTALLATION REQUIREMENTS OPTIMUM ORIENTATION AND TILT
· Ensure that the module meets the general technical system requirements.
· To maximize your annual yield, find out the optimum orientation and tilt for PV modules in your region.
The highest yields are achieved when sunlight shines perpendicularly onto the PV modules. · Ensure that other systems components do not damage the module mechanically or electrically.
· Modules can be wired in series to increase voltage or in parallel to increase current. To connect modules in series, connect the cables from the positive terminal of one module to the negative terminal of the next module.
To connect in parallel, connect the cables from the positive terminal of one module to the positive terminal on the next module.
AVOID SHADING
· Even minor partial shading (e.g. from dirt deposits) reduces yields. A module can be considered to be unshaded if its entire surface is free from shading all year round. Sunlight should be able to reach the module even on the shortest day of the year.
· The quantity of bypass diodes in the module’s junction box provided may vary depending on the model series.
· Only connect the quantity of modules that corresponds to the voltage specifications of the inverters used in the system. In addition, modules must not be connected together to create a voltage higher than the maximum permitted system voltage, even under the worst local temperature conditions (see Table 1 for the correction coefficients that apply to open-circuit voltage).
· Constant shading conditions can affect module service lifetime, due to accelerated ageing of the encapsulation material and thermal stress on the bypass diodes.
RELIABLE VENTILATION
· Sufficient clearance (at least 10 cm (3.94 in)) between the module frame and the mounting surface is required to allow cooling air to circulate around the back of the module. This also enables condensation or moisture to dissipate. · A maximum of two strings can be connected in parallel without using an over-current protection device (fuses, etc.) incorporated in series within each string. Three of more strings can be connected in parallel if an appropriate and certified over-current protection device is installed in series within each string.
· According to UL 1703, any other specific clearance required for maintaining a system fire rating should prevail. Detailed clearance requirements pertaining to system fire ratings must be provided by your racking supplier.
· Only modules with similar electrical outputs should be connected in the same series to avoid or minimize mismatch effects in arrays.
· To minimize risk in the event of an indirect lightning strike, avoid forming loops with the wiring when designing the system.
5.1
MODULE WIRING
CORRECT WIRING SCHEME
· The recommended maximum series fuse rating is stated in a table in the Annex.
· Ensure that the wiring is correct before starting up the system. If the measured open circuit voltage (Voc) and short-circuit current (Isc) differ from the specifications, this indicates that there is a wiring fault.
· Modules should be safely fixed to bear all expected loads, including wind and snow loads.
· A minimum clearance of 6.5 mm (0.25 in) between
· When modules have been pre-installed but the system has not been connected to the grid yet, each module string should be kept under open-circuit conditions
8 | and proper actions should be taken to avoid dust and moisture penetration inside the connectors.
5.2
GROUNDING
CORRECT CONNECTION OF PLUG CONNECTORS
· Make sure that all connections are safe and properly mated. The PV connector should not be subjected to stress from the exterior. Connectors should only be used to connect the circuit. They should never be used to turn the circuit on and off.
· For grounding requirements in North America, a module with exposed conductive parts is considered to comply with UL 1703 only when it is electrically grounded in accordance with both the instructions presented below and the requirements of the National Electrical Code.
Any grounding means used with Canadian Solar Inc. modules should be NRTL certified to UL 467 and UL 2703 standards. Please consult our technical service team for the formal approval process.
· Connectors are not waterproof when unmated. When installing modules, connector should be connected to each other as soon as possible or appropriate measures should be taken to avoid moisture and dust penetrating into the connector.
USE OF SUITABLE MATERIALS
· Only use dedicated solar cable and suitable connectors
(wiring should be sheathed in a sunlight-resistant conduit or, if exposed, should itself be sunlight-resistant) that meet local fire, building and electrical regulations.
Please ensure that all wiring is in perfect electrical and mechanical condition.
· For grounding requirements in other areas, although the modules are certified to Safety Class II, we recommend that they be grounded and that module installation should comply with all local electrical codes and regulations. Grounding connections should be installed by a qualified electrician. Connect module frames together using adequate grounding cables: we recommend using
4-14 mm² (AWG 6-12) copper wire. Holes provided for this purpose are identified with a grounding symbol .
All conductive connection junctions must be firmly fixed.
· Do not drill any extra ground holes for convenience this will void the modules warranty.
· Installers may only use single-conductor cable listed and labeled as USE-2 or PV Wire which is 90°C wet rated in North America, and single conductor cable, 2.5-16 mm 2 (5-14 AWG), 90°C wet rated in other areas (i.e. TUV
2PfG1169 or EN50618 approved), with proper insulation which is able to withstand the maximum possible system open-circuit voltage.
· All bolts, nuts, flat washers, lock washers and other relevant hardware should be made of stainless steel, unless otherwise specified.
· Canadian Solar Inc. does not provide grounding hardware.
· Only copper conductor material should be used. Select a suitable conductor gauge to minimize voltage drop and ensure that the conductor ampacity complies with local regulations (i.e. NEC 690.8(D)).
· One grounding method is recommended for Canadian
Solar Inc. standard modules, as described below. For alternative grounding methods, please refer to Annex B
(Alternative Grounding Methods) on the website (www.
canadiansolar.com).
CABLE AND CONNECTOR PROTECTION
· Secure the cables to the mounting system using UVresistant cable ties. Protect exposed cables from damage by taking appropriate precautions (e.g. placing them inside a metallic raceway like EMT conduit). Avoid exposure to direct sunlight.
· A minimum bending radius of 60 mm (2.36 in) is required when securing the junction box cables to the racking system.
GROUNDING METHOD:
BOLT + TOOTHED NUT + CUP WASHER
· A grounding kit containing an M5 (3/16") SS cap bolt, an
M5 (3/16") SS flat washer, an M5 (3/16") SS cup washer, and an M5 (3/16") SS nut (with teeth) is used to attach copper grounding wire to a pre-drilled grounding hole on the frame (see image above).
· Do not place connectors in locations where water could easily accumulate.
· Place the wire between the flat washer and the cup washer. Ensure that the cup washer is positioned between the frame and the wire with the concave side up to prevent galvanic corrosion. Tighten the bolt securely using
EN-Rev IM/GN-ADM-EU/1.1 Copyright © April 2019. Canadian Solar Inc.
the SS toothed nut. A wrench may be used to do this.
The tightening torque is 3-7 Nm (2.2-5.2 ft-lbs).
6.0 MOUNTING INSTRUCTIONS
· The mounting design must be certified by a registered professional engineer. The mounting design and procedures must comply with all applicable local codes and requirements from all relevant authorities. The module is considered to be in compliance with UL 1703 and IEC
61215 only when the module is mounted in the manner specified by the mounting instructions included in this installation manual.

Methods) on our website (www.canadiansolar.com). For information about other installation methods, please contact your local representative. Failure to use a recognized installation method will void the Canadian Solar
Inc. warranty.
· Use appropriate corrosion-proof fastening materials. All mounting hardware (bolts, spring washers, flat washers, nuts) should be hot dip galvanized or stainless steel.
· Any module without a frame (laminate) shall not be considered to comply with the requirements of UL 1703 unless the module is mounted with hardware that has been tested and evaluated with the module under this standard or by a field Inspection certifying that the installed module complies with the requirements of UL
1703.
· Use a torque wrench for installation.
· Do not drill additional holes or modify the module frame.
Doing so will void the warranty.
· Canadian Solar Inc. does not provide mounting hardware.
· Standard modules can be mounted onto a support struc-
· Standard modules can be installed in either landscape or portrait orientations. Refer to the detailed instructions for further guidance. Please note that in areas with heavy snowfall (> 2400 Pa) further countermeasures such the use of additional support bars should be considered to avoid snow loads damaging the lowest row of modules.

act your professional structural engineer.
· In cases where an additional support bar is recommended to improve both mechanical stability and long-term module performance, we recommend selecting a sufficiently resistant material. Canadian Solar Inc. recommends bars with a minimum thickness of 50mm (1.97 in). The support bar centerline should be positioned within 100 mm (3.94 in) of the side frame centerline (slight shifts may be necessary to access module grounding holes).
· The load described in this manual corresponds to test load. For installations complying with IEC 61215-2:2016 and UL 1703, a safety factor of 1.5 should be applied for calculating the equivalent maximum authorized design loads. Project design loads depend on construction, applicable standards, location and local climate. Determination of the design loads is the responsibility of the racking suppliers or professional engineers. For detailed information, please follow local structural code or cont-
6.1 MOUNTING METHOD: BOLTING

annex D: moDule CleanIng guIDelInes
This manual covers the requirements for the cleaning procedure of Canadian Solar Inc. photovoltaic modules.
The purpose of these cleaning guidelines is to provide general information for cleaning Canadian Solar modules.
System users and professional installers should read these guidelines carefully and strictly follow these instructions.
· Do not use de-greasers on the module.
· Do not use cleaning corrosive solutions containing acid, alkali, acetone, or industrial alcohol.
· Canadian Solar Inc. recommends to avoid rotating brush cleaning methods, as they could create micro-cracks in the PV modules.
Failure to follow these instructions may result in death, injury or damage to the photovoltaic modules. Damages induced by inappropriate cleaning procedures will void
Canadian Solar Inc. warranty.
· Dirt must never be scraped or rubbed away when dry, as this will cause micro-scratches on the glass surface.
safetY WaRnIng
· Cleaning activities create risk of damaging the modules and array components, as well as increasing the potential electric shock hazard.
opeRatIon pRepaRatIon
· Noticeable dirt must be rubbed away by gentle cleaning implement (soft cloth, sponge or brush with soft bristles).
· Ensure that brushes or agitating tools are not abrasive to glass, EPDM, silicone, aluminum, or steel.
· Cracked or broken modules represent an electric shock hazard due to leakage currents, and the risk of shock is increased when modules are wet. Before cleaning, thoroughly inspect modules for cracks, damage, and loose connections.
· The voltage and current present in an array during daylight hours are sufficient to cause a lethal electrical shock.
· Conduct the cleaning activities avoiding the hottest hours of the day, in order to avoid thermal stress on the module.
We recommend the following to be used:
· Water with low mineral content
· Near neutral pH water
· The maximum water pressure recommended is 4 MPa (40 bar)
· Ensure that the circuit is disconnected before starting the cleaning procedure as contact with leakage of electrically active parts can result in injury.
· Ensure that the array has been disconnected to other active components (such as inverter or combiner boxes) before starting with the cleaning.
CleanIng methoDs
· Wear suitable protection (clothes, insulated gloves, etc.).
methoD a: CompResseD aIR
Canadian Solar Inc. recommends cleaning the soft dirt (like dust) on modules just with air pressure. This technique can be applied as long as the method is efficient enough considering the existing conditions.
· Do not immerse the module, partially or totally, in water or any other cleaning solution.
hanDlIng notICe methoD B: Wet CleanIng
If excessive soiling is present on the module surface, a non-conductive brush, sponge, or other mild agitating method may be used with caution.
· Use a proper cleaning solution and suitable cleaning equipment.
· Do not use abrasive or electric cleaners on the module.
· Particular attention should be taken to avoid the module glass or frame to come in contact with sharp objects, as scratches may directly affect product safety.
· Ensure that any brushes or agitating tools are constructed with non-conductive materials to minimize risk of electric shock and that they are not abrasive to the glass or the aluminum frame.
· If grease is present, an environmental friendly cleaning agent may be used with caution.
