Mounting with Clamps
Four or more corrosion-proof aluminum clamps should be used to fasten SF modules to the support structure. Center-line of the
clamps shall be secured within at the indicated clamping zone (256 mm ± 75 mm) from the corners of the longer side of the module
frame using stainless-steel M8 bolts with a minimum length of 20 mm. Tighten the clamps with an adequate torque value. *

All selected module clamps must be at least 50 mm long, 3 mm thick, and overlap the module frame by 8 mm 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.

UL:
Recommended tightening torque is 15 Nm (132.8 lb in) minimum.
TUV: 2,400 Pa (50 lbs/ft2) to the front and back of the module
UL: 1,600 Pa (33.4 lbs/ft2) to the front and back of the module
1.5 times the design load is applied to the module during UL testing. 2,400 Pa (50 lbs/ft2) is applied to test 1,600 Pa
(33.4 lbs/ft2) UL design load.
