persons near the installation site or
storage area of modules.
· If the disconnects and over current protective
devices (OCPD) 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.
· Use electrically insulated tools to reduce the risk of
electric shock.
·
Do not
use or install broken modules.
· Contact with module surfaces or frames may cause
electric shock if the front or rear glass is broken.
· Keep the junction box cover closed at all times.
·
Do not
connect or disconnect modules when
current from the modules or an external source is
present.
·
Do not
disassemble a module or remove any
module part.
·
Do not
artificially concentrate sunlight onto
a module.
· The PV module does not contain any serviceable parts.
Do not attempt to repair any part of the module.

MECHANICAL / ELECTRICAL
SPECIFICATIONS
Module electrical ratings are measured under Stan-
dard Test Conditions (STC) of 1 kW/m2 irradiance,
with an air mass (AM) spectrum of 1.5, and a cell
temperature of 25°C. Detailed electrical and mecha-
nical characteristics of Canadian Solar Inc. crystalline
silicon PV modules can be found in Annex A (Mecha-
nical And Electrical Ratings). Main electrical charac-
teristics under STC are also stated on each module
label. The maximum system voltage for double glass
module type is 1000V (UL) and 1500V (IEC).
Under certain conditions, a module may produce
more current or voltage than its STC rated power. As
a result, a module open-circuit voltage and short-
circuit current under STC should be multiplied by
1.25 when determining component voltage ratings,
conductor ampacities, overcurrent device ratings,
and the size of controls connected to the PV output.
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, as
described in section 690-8 of U.S. NEC.

UNPACKING AND STORAGE
PRECAUTIONS
· Module should be stored in a dry and ventilated
environment to avoid direct sunlight and
moisture. If modules are stored in an uncontrolled
environment, the storage time should be less than
3 months and extra precautions should be taken
to prevent moisture exposure to connectors or
sunlight exposure to modules.
· Unpack module pallets carefully, following the
steps shown on the pallet. Unpack, transport and
store the modules with care.
· Modules must always be unpacked by two people.
When handling modules always use both hands.
·
Do not
lift modules by their wires or junction box;
lift them by the frame.
· No stacking of modules.
·
Do not
place excessive loads on the module or
twist the module frame.
·
Do not
stand, step, walk and/or jump on modules.
