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.
6.1.2.6
Connecting protruding cables
In the case of connection cables brought out of the machine, no terminal board is installed on
the terminal base of the machine housing. The connection cables are directly connected to
stator winding terminals at the factory.
The connection cables are color-coded or labeled. The customer directly connects individual
cables in the control cabinet for their system in accordance with the labeling.
