CORRECT CONNECTION
OF PLUG CONNECTORS
•
Make sure that all connections are safe and pro-
perly mated. The PV connectors should not be
subjected to stress from the exterior. Connec-
tors 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, connectors should be
connected to each other as soon as possible or
appropriate measures (like using connector en-
dcaps) should be taken to avoid moisture and
dust penetrating into the connector.
•
Do not clean or precondition the connectors
using lubricants or any unauthorized chemical
substances.
USE OF SUITABLE MATERIALS
•
Only use dedicated solar cable and suitable
plugs (wiring should be sheathed in a sun-
light-resistant conduit or, if exposed, should
itself be sunlight-resistant) that meet local fire,
building and electrical regulations. Please en-
sure 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, 4-16 mm² (5-12 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 pos-
sible system open-circuit voltage. Only copper
conductor material should be used. Select a sui-
table conductor gauge to minimize voltage drop
and ensure that the conductor ampacity com-
plies with local regulations (i.e. NEC 690.8(D)).
CABLE AND CONNECTOR PROTECTION
•
Secure the cables to the mounting system
using UVresistant cable ties. Protect exposed
cables from damage by taking appropriate pre-
cautions (e.g. placing them inside a metallic
raceway like EMT conduit). Avoid exposure to
direct sunlight.
•
A minimum bending radius of 60mm (2.36 in) is
required when securing the junction box cables
to the racking system.
•
Protect exposed connectors from weathering
damage by taking appropriate precautions.
Avoid exposure to direct sunlight.
•
Do not place connectors in locations where wa-
ter could easily accumulate.
5.2
GROUNDING
•
For grounding requirements in North Ameri-
ca, 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 So-
lar 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, al-
though 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 re-
gulations. Grounding connections should be
installed by a qualified electrician. Connect mo-
dule frames together using adequate groun-
ding cables: we recommend using 4-14 mm²
(AWG 6-12) copper wire. Holes provided for this
purpose are identified with a grounding symbol
(IEC61730-1). All conductive connection
junctions must be firmly fixed.
•
Do not drill any extra ground holes for conve-
nience as 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.
•
EDF ENR PWT does not provide grounding hard-
ware.
•
One grounding method is recommended for
EDF ENR PWT standard modules, as descri-
bed below. For alternative grounding methods,
please refer to Annex B (Alternative Grounding
Methods).
