· If the disconnects and Over Current Protection
Device (OCPD)'s cannot be opened or the inverter
cannot be powered down, cover the fronts of
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 broken 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
artificially 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 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.
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 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.
