· Make sure that all connections are safe and
properly mated. The PV connector should not be
subjected to stress from the exterior. Connectors
should only be used to connect the circuit. They
should never be used to turn the circuit on and off.
· Connectors are not waterproof when unmated.
When installing modules, connector should be
connected to each other as soon as possible or
appropriate measures should be taken to avoid
moisture and dust penetrating into the connector.

· Only use dedicated solar cable and suitable
connectors (wiring should be sheathed in a
sunlight-resistant conduit or, if exposed, should be
sunlight-resistant itself) that meet local fire, building
and electrical regulations. Please ensure that
all wiring is in perfect electrical and mechanical
condition.
· Installers may only use single-conductor cable
listed and labeled as USE-2 or PV wire which
is 90°C wet rated in North America, and single
conductor cable, 2.5-16 mm² (5-14 AWG ), 90°C wet
rated in other areas (i.e. TUV 2PfG1169 or EN50618
approved), with proper insulation which is able to
withstand the maximum possible system open-
circuit voltage.
· Only copper conductor material should be used.
Select a suitable conductor gauge to minimize
voltage drop and ensure that the conductor
ampacity complies with local regulations (i.e. NEC
690.8(D)).

· Secure the cables to the mounting system using
UV-resistant cable ties. Protect exposed cables
from damage by taking appropriate precautions
(e.g. placing them inside a metallic raceway like
EMT conduit). Avoid exposure to direct sunlight.
· A minimum bending radius of 60 mm (2.36 in) is
required when securing the junction box cables to
the racking system.
· Do not place connectors in locations where water
could easily accumulate.

· For grounding requirements in North America,
a module with exposed conductive parts is
considered to comply with UL 1703 only when
it is electrically grounded in accordance with
both the instructions presented below and the
requirements of the National Electrical Code. Any
grounding means used with Canadian Solar Inc.
modules should be NRTL certified to UL 467 and
UL 2703 standards. Please consult our technical
service team for the formal approval process.
· For grounding requirements in other areas,
although the modules are certified to Safety Class
II, we recommend them to be grounded and
that module installation should comply with all
applicable local electrical codes and regulations.
· Grounding connections should be installed by a
qualified electrician.
· Connect module frames together using adequate
grounding cables: we recommend using 4-14 mm²
(AWG 6-12) copper wire. Holes provided for this
purpose are identified with a grounding symbol
(IEC 61730-1). All conductive connection
junctions must be firmly fixed.
· Do not drill any extra ground holes for
convenience this will void the modules warranty.
· All bolts, nuts, flat washers, lock washers and other
relevant hardware should be made of stainless
steel, unless otherwise specified.
· Canadian Solar Inc. does not provide grounding
hardware.
· One grounding method is recommended for
Canadian Solar Inc. standard modules, as
described below. For alternative grounding
methods, please refer to Annex B (Alternative
Grounding Methods) on the website (www.
canadiansolar.com). It is not possible to use
standard grounding methods for certain module
ranges. Please refer to Annex B for more details.
