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
PV modules are 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.
It is recommended that PV modules are installed in an
environmental temperature range of -40 °C to + 40 °C.
For modules operating under such conditions, the 98th-
percentile of the module operational temperature must
be of 70 °C or lower. CS7L-MS-R modules are designed
for application where the 98th-percentile of the module
operational temperature is up to 80 °C.
This environmental temperature range encompasses
many locations and installation styles in these locations.
Annex B provides the reader with modelled PV module
temperature examples, at the 98th-percentile
depending on the different mounting method and
worldwide locations.
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.
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).
A maximum of two strings can be connected in parallel
without using an over-current protection device (fuses,
