Earthing
For safety reasons, it is very important that the motor be
properly and carefully earthed.
It is essential to use the earthing terminal
in the terminal box. In addition, an earth-
ing screw is provided on the motor frame
for the connection of a protective or earth-
ing conductor as specified in VDE 0100 and
VDE 0141 respectively.
When using shielded power cables, make sure the cable
shield metal contacts the motor frame over a large area.
This is achieved, for example, by special cable glands pro-
vided for shield contact.
Short-circuiting
The motor terminals of the synchronous lift
machines, type WSG, can be short-circuit-
ed, if required, to brake the lift machine
faster. This is, however, only permissible at
speeds less than the rated speed of the
respective motor.
