GROUNDING

·  Although the modules are certified to Safety Class 

II, we recommend that they are grounded and that 
module installation should comply with all local 
electrical codes and regulations.  

·  Grounding connections should be installed by a 

qualified electrician.

·  Connect module frames together using adequate 

grounding cables: Canadian Solar recommends 
using 4-14 mm² (AWG 6-12) copper wire. Holes 

provided for this purpose are identified with a 

grounding symbol           . All conductive connection 

junctions must be firmly fixed.

·  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 with 5 mm 

(0.20 in) grounding holes, as described below. For 
alternative grounding methods, please refer to 
our Installation Manual Annex (Section 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.

GROUNDING METHOD: 
BOLT + TOOTHED NUT + CUP WASHER.

·  A grounding kit containing an M5 (3/16") SS cap 

bolt, an M5 (3/16") SS flat washer, an M5 (3/16") SS 

cup washer, and an M5 (3/16") SS nut (with teeth) 
is used to attach copper grounding wire to a pre-
drilled grounding hole on the frame (see image 
below). 

·  Place the wire between the flat washer and the cup 

washer. Ensure that the cup washer is positioned 
between the frame and the wire with the concave 
side up to prevent galvanic corrosion. Tighten the 
bolt securely using the SS toothed nut. A wrench may 
be used to do this. The tightening torque is 3-7 Nm 
(2.2-5.2 ft-lbs).

To fix the wire between 
the flat washer and 

cup washer, place the 
cup washer (concave 
side up) between the 
frame and the wire.

Then tighten the bolt 
using the toothed nut.
