• 

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 above). The 

grounding holes are located at the upper and lower 

edges of the long side frame, close to the module 

short sides.

• 

Mounting rail designs should be such to allow easy 

access to the grounding holes located on the long 

side of the frame, in order to enable the equipment 

grounding function when required.

• 

Place the wire between the flat washer and the cup 

washer. Ensure that the cup washer is positioned be-

tween 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).

MOUNTING INSTRUCTIONS

The applicable regulations pertaining to work 

safety, accident prevention and securing the 

construction site must be observed. Workers 

and third party personnel shall wear or install 

fall arrest equipment. Any third party need to be protect-

ed against injuries and damages.

• 

The mounting design must be certified by a regis-

tered professional engineer. The mounting design 

and procedures must comply with local codes and 

requirements from all relevant authorities.

• 

The loads described in this manual correspond to 

test loads. For installations complying with UL 1703 

or UL 61730 and IEC 61215-2:2016, a safety factor of 

1.5 should be applied for calculating the equivalent 

maximum authorized design loads. Project design 

loads depend on construction, applicable stan-

dards, location and local climate. Determination of 

the design loads is the responsibility of the racking 

suppliers and/or professional engineers. For detailed 

information, please follow local structural code or 

contact your professional structural engineer.

1.  To fix the wire between the 

flat washer and cup washer, 

place the cup washer 

(concave side up) between 

the frame and the wire.

2.  Then tighten the bolt 

using the toothed nut.

• 

Use appropriate corrosion-proof fastening materials. 

All mounting hardware (bolts, spring washers, flat 

washers, nuts) should be hot dip galvanized or stain-

less steel.

• 

Use a torque wrench for installation.

• 

Do not drill additional holes or modify the module 

frame. Doing so will void the warranty.

WHEN CLAMPS ARE USED AS FIXING MATERIAL

• 

Install and tighten the module clamps to the mount-

ing rails using the torque stated by the mounting hard-

ware manufacturer. System designer and installer are 

responsible for load calculations and for proper de-

sign of support structure. It is recommended to use 

a torque wrench for installation. Tightening torques 

must respectively be within 16~20 Nm (11.8~14.75 ft-

lbs) for M8 x 1.25-Grade 8.8 (5/16”-18 Grade B7) gal-

vanized or A2-70 stainless steel coarse thread bolts, 

depending on bolt class. The yield strength of bolt 

and nut should not be less than 450 MPa.

• 

Clamp material should be anodized aluminum alloy 

or steel of appropriate grade.

• 

Clamp positions are of crucial importance for the re-

liability of the installation, the clamp centerline must 

only be positioned within the authorized position 

ranges indicated below, depending on the configu-

ration and load.
