CORRECT CONNECTION OF CONNECTORS

 

 

Make  sure  that  all  connections  are  safe  and  properly 
mated. The PV connector should not be subject 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 
(like using connector endcaps) should be taken to avoid 
moisture and dust penetrating into the connector. 

 

Do not

 connect different connectors (brand and model) 

together. 

 

Do  not

  clean  or  precondition  the  connectors  using 

lubricants or any unauthorized chemical substances. 

 

For CS6R and CS6RA modules, do not short-circuit the 
modules before full operation. 

USE OF SUITABLE MATERIALS 

 

Only use dedicated solar cable and suitable connectors 
(wiring  should  be  sheathed  in  a  sunlight-resistant 
conduit  or,  if  exposed,  should  itself  be  sunlight-
resistant)  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 PV wire which is 90°C wet rated in North 
America,  and  single  conductor  cable  with  a  cross 
section area of at least 4 mm² (12 AWG), 90°C wet rated 
in  other  areas  (i.e.  IEC  62930:  2017  approved),  with 
proper  insulation  which  is  able  to  withstand  the 
maximum  possible  system  open-circuit  voltage.  For 
CS7N and CS7L modules, Canadian Solar recommends 
the  use  of  a  copper  wire  of  at  least  6  mm

2

  (10AWG) 

section. 

 

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)). 

CABLE AND CONNECTOR PROTECTION 

 

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. 

 

Protect exposed connectors from weathering damage 
by  taking  appropriate precautions. Avoid  exposure to 
direct sunlight. 

 

Do not place connectors in locations where water could 
easily accumulate. 

5.2 GROUNDING 

 

For  grounding  requirements  in  North  America,  a 
module with exposed conductive parts is considered to 
comply  with  UL  61730  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 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.  Minimum  size  of 
equipment grounding conductors for ground raceway 
and  equipment  from  NEC  690.8(D)  should  be 
considered. 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 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.
