requirements on the clamping system for framed modules
When using framed Solibro products, it is important to ensure that
there is no potential difference between frame and ground. There
are two options available for this:
option 1:
usage of grounding clamps with grounding function
specifiedintheapprovedSolibroclampslist.Onrequest,Solibro
can test clamp systems and approve them following successful
testing.
option 2:
Potential equalization of the module must be done via
one of the grounding holes on the module frame. in that case,
usageofclampswithoutgroundingfunctionisvalidiftheyfulfil
the following requirements:
clamp height corresponding to 30 mm frame height.
clamp depth: 7–12 mm.
