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 po-

sitioned between the frame and the wire with 

the concave side up to prevent galvanic cor-

rosion. 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).

MOUNTING INSTRUCTIONS

The applicable regulations pertaining 

to  work  safety,  accident  prevention  and                    

securing the construction site must be 

observed. Workers and third party per-

sonnel shall wear or install fall arrest equipment. 

Any third party need to be protected against inju-

ries and damages.

• 

The mounting design must be certified by a re-

gistered professional engineer. The mounting 

design and procedures must comply with all 

applicable local codes and requirements from 

all relevant authorities. 

• 

The module is considered to be in compliance 

with UL 1703 and IEC 61215 only when the mo-

dule is mounted in the manner specified by the 

mounting instructions included in this installa-

tion manual.

• 

Any module without a frame (laminate) shall not 

be considered to comply with the requirements 

of UL 1703 unless the module is mounted with 

hardware that has been tested and evaluated 

with the module under this standard or by a field 

inspection certifying that the installed module 

complies with the requirements of UL 1703.

• 

EDF ENR PWT  does not provide mounting hard-

ware.

• 

Standard modules can be mounted onto a sup-

port structure using one of several approved 

methods. One of such methods is described be-

low. For details of other mounting methods and 

the methods recommended by Canadian Solar 

Inc. for special module ranges, please refer to 

the Annex A (Alternative Mounting Methods) of 

this installation manual. For information about 

other installation methods, please contact your 

local representative. Failure to use a recognized 

installation method will void the EDF ENR PWT 

warranty.

• 

Use appropriate corrosion-proof fastening 

materials. All mounting hardware (bolts, spring 

washers, flat washers, nuts) should be hot dip 

galvanized or stainless steel.

• 

Use a torque wrench for installation.

• 

Do not drill additional holes or modify the 

module frame. Doing so will void the warranty. 

• 

Standard modules can be installed in either 

landscape or portrait orientations. Refer to 

the detailed instructions for further guidance. 

Please note that in areas with heavy snowfall (> 

2400 Pa) further countermeasures such the use 

of additional support bars should be conside-

red to avoid snow loads damaging the lowest 

row of modules.

• 

In cases where an additional support bar is re-

commended to improve both mechanical sta-

bility and long-term module performance, we 

recommend selecting a sufficiently resistant  

material. EDF ENR PWT recommends bars with 

a minimum thickness of 50 mm (1.97 in). The 

support bar centerline should be positioned 

within 100 mm (3.94 in) of the side frame cen-

terline (slight shifts may be necessary to access 

module grounding holes).

• 

The loads described in this manual correspond 

to test loads. For installations complying with 

IEC  61215-2: 2016 and UL 1703, a safety fac-

tor of 1.5 should be applied for calculating the 

equivalent maximum authorized design loads. 

Project design loads depend on construction, 

applicable standards, location and local cli-

mate. Determination of the design loads is 

1.  To fix the wire between      

the flat washer and cup wa-

sher, place the cup washer 

(concave side up) between 

the frame and the wire.

2.  Then tighten the bolt     

using the toothed nut
