10.2.2 Clamp dimensions
Observe the following information for clamp lengths and depths.
Clamp lengths and depths
Fig. 8
Definition of clamp length and depth for framed modules
a
: Clamp length
b
: Clamp depth
The required minimum length of a clamp (parallel to the frame
side) is 30 mm.
The required minimum depth of a clamp (perpendicular to the
frame side) is 3 mm.
aleo solar recommends a clamp depth of 5 mm.
Depending on the ambient conditions (e.g. angle, suction load
or tolerances of the substructure) a higher minimum area per
clamp may be required.
Observe the instructions of the clamp manufacturer.
10.2.3 Tightening torque for clamp mounting
Tighten the screws on the clamp manually. If you use an automatic
screwdriver, then set a suitable maximum tightening torque. You
can find details for this in the manufacturer’s documentation for
the substructure.
