RELIABLE VENTILATION
Sufficient clearance (at least 102 mm (4.02 in)) between
the module frame and the mounting surface is required
to allow cooling air to circulate around the back of the
module. This also allows condensation or moisture to
dissipate.
According to UL 61730, any other specific clearance
required for maintaining a system fire rating should
prevail. Detailed clearance requirements pertaining to
system fire ratings must be provided by your racking
supplier.
5.1 MODULE WIRING
CORRECT WIRING SCHEME
Cable management scheme should be reviewed and
approved by the EPC contractor; in particular required
cable lengths should be cross-checked considering the
specificities of the tracker structure like bearing house
gaps. If longer cable or additional jumper cables are
requested, please contact Canadian Solar’s sales
representative in advance.
Ensure that the wiring is correct before starting up the
system. If the measured open circuit voltage (Voc) and
short-circuit current (Isc) differ from the specifications,
this indicates that there is a wiring fault.
When modules have been installed but the system has
not been connected to the grid yet, each module string
should be kept under open-circuit conditions and
proper actions should be taken to avoid dust and
moisture penetration inside the connectors.
In case where a cable connection method not included
in the below table is used, please confirm the suitable
cable length with Canadian Solar’s sales representative.
For different Canadian Solar module types, Canadian
Solar offers optional cable lengths to match various
system configurations.
Please remember that when ordering Canadian Solar
modules with portrait cables (short cables) extension
cables is provided in each pallet.
Recommended system cable schemes are shown in
table 2 & 3 below:
