Protruding connection cables

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
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
• Use O-rings or suitable flat gaskets to seal entries in cover plates (DIN 42925) and other
• Seal the terminal base of the machine enclosure using the original seal of the cover plate to
• Please observe the tightening torques for cable entries and other screws.
6.2.1.7

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.
6.2.1.8

Connection with/without cable lugs

In the case of terminals with terminal clamps, distribute the conductors in such a way that the
clamping heights on both sides of the fillet are about the same. This method of connection
requires that you must bend a single conductor in a U shape or use a cable lug. The same applies
to the inner and outer terminals of the ground conductor.
When connecting up using cable lugs, select their size corresponding to the required cable cross-
section and the stud size. An inclined arrangement is only permitted provided the required air
clearances and creepage distances are carefully maintained.
