damaged.
This may have the following causes:
• Passage points, where connection cables are
passed through windows or doors.

erly fastened or routed.
• Places where the connection cables have been cut
due to being driven over.
• Insulation damage due to being ripped out of the
wall outlet.
• Cracks due to the insulation ageing.
Such damaged electrical connection cables must not
be used and are life-threatening due to the insulation
damage.
Check the electrical connection cables for damage
regularly. Make sure that the connection cable does
not hang on the power network during the inspection.
Electrical connection cables must comply with the ap-
plicable VDE and DIN provisions. Only use connection
cables with the marking „H05VV-F".
