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 “Type 1” or
“Type 2” fire rated modules, are considered acceptable
for use with Canadian Solar modules, provided 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.
When installing modules, ensure the assembly is
mounted over 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 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 connectors to any
unauthorized chemical substances (e.g. oil, lubricant,
pesticide, etc.), as modules may incur damages.
Canadian solar modules have passed salt mist
corrosion resistance test according to IEC 61701, but
the corrosion may still occur on where the modules
frame is connected to the bracket or where the
grounding is connected. Should the installation location
be near the ocean, Canadian solar recommends
stainless steel or aluminum materials be used in the
areas with direct contact with the PV modules, and the
connection point should be protected with anti-
corrosion measures. For more information, please
contact Canadian solar technical support team.
CS7L-MS & CS7N-MS modules, when used in rooftop
applications, should be installed in a way that ensures
enough ventilation. The clearance between lowest
point of module and the roof surface MUST be equal to
or greater than 102 mm, tilt angle of module to roof
surface should be equal to or greater than 15°, and
wind shields or decorative sheets which will prevent
ventilation around PV array are NOT allowed to be
installed.
Failure to comply with these instructions will void
Canadian Solar 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
