The screw-type connections must have been matched to the connecting cables used
(diameter armoring, braid, shield).

protection (water and dust) - as well as the temperature range in operation stamped on the
rating plate.

6.2.2.6 Protruding connection cables
WARNING
Risk of short-circuit and voltage hazard
A short circuit can occur if connecting cables are clamped and crushed between parts of
the enclosure and the cover plate.
This can result in death, severe injury and material damage.
•
During disassembly and particularly when installing the cover plate, make sure that the
connecting cables are not clamped between enclosure parts and the cover plate.
CAUTION
Damage to connecting cables that are freely led out
You must observe the following note to avoid damaging connecting cables that are freely
led out:
•
It must be ensured that there are no foreign bodies, dirt, or moisture in the terminal base
of the machine enclosure.
•
Use O-rings or suitable flat gaskets to seal entries in cover plates (DIN 42925) and other
open entries.
•
Seal the terminal base of the machine enclosure using the original seal of the cover
plate to prevent dust and water from entering.
•
Please observe the tightening torques for cable entries and other screws.
