When installing modules in light rain,
morning dew, take appropriate measures
to prevent water ingress into the
connector.
Do not allow children or unauthorized
persons near the installation site or
storage area of modules.
· Do not install modules in strong wind.
· Use electrically insulated tools to reduce the risk
of electric shock.
· If the disconnects and Over Current Protection
Device (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.
·
Do not use or install damaged modules.
· Contact with module surfaces or frames may cause
electric shock if the front glass is broken or the
backsheet is torn.
· 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 articially concentrate sunlight on a module.
· Do not connect or disconnect modules when current
from the modules or an external source is present.

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
our Installation Manual Annex ( Section Annex C:
Module Specications) 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.
Under certain conditions, a module may produce
more current or voltage than under its Standard Test
Condition's rated power. As a result, the module
short-circuit current 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.
