Notes on statics
Reliable distributed load when using SOL– 50 solar fasteners in steel trapezoid sheets – alu-
minium sheets and corrugated fibre cement sheets. Bolting to sub-construction, steel or
wood purlins.
The length of the cantilever arm should be at least 0.2 times and no more than 0.4 times the
span distance calculated!
Higher span distances and cantilever arm lengths differing from these are possible in special circum-
stances. Do not hesitate to contact us by telephone if you have any questions.
Potential equalisation
The PV generator, (the assembly frame) must be included in the potential equalisation.
To create the potential equalisation, use a 10mm² copper cable and the earthing set provided, con-
sisting of plastic connector and clamp. (Item no. 30539)
The earthing set is attached with two stainless steel, self-cutting screws (supplied) to a suitable point
on the vertical profile.
The counterpart is placed on the potential equalisation rail.
The potential equalisation must be carried out in accordance with VDE 0100.
