a) Fastening the module by simultaneous
screwing in and tightening of the screws.
b) Fastening the module while holding down
the module during screwing.

Alternatively one screw can be applied initially. It is important that the module does not rise up. To
prevent this, the first screw has to be loosely tightened to avoid a press force to the clamp (Figure 13a).
Afterwards the second screw has to be fully tightened (Figure 13b). Finally the first and still loose screw
has to be fully tightened (Figure 13c).
a) Step 1
b) Step 2
c) Step 3
