4.0 UNPACKING AND STORAGE
Precautions
Modules 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 connectors from being exposed to moisture or sunlight, like using connector endcaps.
Unpack module pallets carefully, following the steps shown on the pallet.
Unpack, transport and store the modules with care.
Modules must always be unpacked and installed by two people. Always
use both hands when handling modules.
Do not lift modules by their wires or junction box, lift them by the frame.
Stacks of modules should contain no more than 12 modules, and the
frames should be aligned.
Do not place excessive loads on the module or twist the module frame.
Do not stand, step, walk and/or jump on modules under any
circumstances. Localized heavy loads may cause severe micro-cracks at cell level, which in turn may
compromise module reliability. and void Canadian Solar Inc’s warranty.
Do not support the module by the backsheet when handling or installing the module.
Do not carry modules on your head.
Do not drop or place objects (such as tools) on the modules.
Do not use sharp instruments on the modules. Particular care should be taken to avoid module backsheets
being damaged by sharp objects, as scratches may directly affect product safety.
Do not leave modules unsupported or unsecured.
Do not change the wiring of bypass diodes.
Keep all electrical contacts clean and dry at all times.
Do not expose the modules and its electrical contacts to any unauthorized chemical substance (e.g. oil,
lubricant, pesticide, etc.).
Product identification
Each module has three identical barcodes (one in
the laminate under the front glass, the second on
the rear side of the module and the third on the frame) that act as a unique identifier. Each module has a
unique serial number containing 13 (pre-March 2013) or 14 (post-March 2013) digits.
A nameplate is also affixed to the rear of each module. This nameplate specifies the model type, as well as
the main electrical and safety characteristics of the module.
5.0 MODULE INSTALLATION
Precautionary Measures and General Safety
Prior to installing modules please obtain information about any requirements and
necessary approvals for the site, installation and inspection from the relevant authorities.
Check applicable building codes to ensure that the construction or structure (roof,
facade, support, etc.) can bear the module system load.
CS-series solar modules have been qualified for Application Class A (equivalent to Safety Class II
requirements). Modules rated under this class should be used in systems operating at voltage above 50V or
power above 240W, where general contact access is anticipated.
Canadian Solar Inc. modules have been certified as Type 1 or Type 4 according to UL 61730 and Class C
