according to IEC 61730-2, please refer to the datasheet or the product nameplate for the detailed types.
Consult your local authority for guidelines and requirements for building or structural fire safety.
UL 61730 system fire rating requirements
A photovoltaic systems composed of UL 61730 certified modules mounted on a UL 2703 certified
mounting system should be evaluated in combination with roof coverings in accordance with UL 61730
standard, with respect to meeting the same fire classification as the roof assembly.
Mounting systems with a System Fire Class Rating (Class A, B or C), tested in conjunction with fire rated
“Type 1” or “Type 4” rated modules, are considered acceptable for use with Canadian Solar Inc. modules,
provides 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.
When installing modules, ensure the supporting roof has a fire resistant roof covering rated for the
application.
The fire rating for this module is only valid when the product is installed as specified in the mechanical
mounting instructions.
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.
Please consult the Canadian Solar Inc. technical support department for more information on the use of
modules in special climates, such as an altitude greater than 2000m.
Do not install modules near open flames or flammable materials.
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 sulfur (i.e. sulfur sources, volcanoes) incurs the risk
of module corrosion.
Do not expose modules and their electrical contacts to any unauthorized chemical substances (e.g. oil,
lubricant, pesticide, etc. ), as modules may incur damages.
Failure to comply with
these instructions
will void Canadian Solar Inc. warranty.
Installation Requirements
Ensure that the module meets the
general technical system
requirements.
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.
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 stated on the module nameplate, even under the worst local
temperature conditions (see Table 1 for the correction coefficients that apply to open-circuit voltage).
