the clamps shall be secured within the indicated clamping zone (256mm
12
75mm) from the corners of the longer module
frame using stainless-steel M8 bolts with a minimum length of 20mm. Tighten the clamps with an adequate torque value.
UL: Recommended tightening torque is 15 N-m (132.8 lb-in) minimum.
All selected module clamps must be at least 30mm long, 3mm thick in case of Aluminum material, and overlaps the module
frame by 8mm or more.
Clamps must not create shadow nor cover the front glass and shall not deform the module frames during installation.
Please refer to the instructions provided by the clamp manufacturer for further instructions.
TUV: 2400Pa (50 lbs/ft
2
) to the front and back of the module
UL: 1600 Pa (33.4 lbs / ft
2
) to the front and back of the module
1.5 times the design load is applied to the module during UL testing. 2400 Pa (50 lbs /ft
