The power distribution box should be checked for defects
before each use. A qualified electrician must eliminate any
defects before use.
What kind of defects can occur?
Defective enclosure (e. g. major deformations, cracks,
breaks).
Defective or missing components (e. g. sockets, hinged
lids for sockets, inspection window).
Defective electrical lines (e. g. kinks, cuts, pinched
points).
Defective or missing protective elements.
What should you pay attention to before use?
Check the power distribution box for defective or mis-
sing components and replace these as needed.
Replace defective seals (e. g. at sockets, plugs, inspec-
tion window, etc.).
Clean soiled components, especially contact parts.
If there are scorch marks on contact parts (e. g. welding
beads), have a qualified electrician replace the affected
plugs and sockets.
Only put fault-free power distribution boxes into service.
5.6 Earthing of power distribution box
(optional)
The power distribution box must be properly
earthed before it is put into service and with due
consideration of the standards DIN VDE 0100-410
and DIN VDE 0100-540.
Additional earthing via optional ground terminals
can be required, dependent on the mains type.
Do not connect any electrical consumers to
the power distribution box, unless it is properly
earthed.

The power distribution box can be equipped with an opti-
onal ground terminal for the additional connection of an
earthing wire.
Loosen the ground terminal by rotating it to the left-
hand side.
Connect the earthing wire.
Fasten the earthing wire by rotating the ground terminal
to the right-hand side.
Check the earthing wire for tight fit.
