NOTE
It is recommended to use a shielded motor cable in order to reduce cable radiation.

CAUTION
:
Switching the unit off and on repeatedly with the mains power supply at short inter-
vals can damage the switch-on current limiter. Because of this the unit should always
be started and stopped with the control unit or via the STF/STR and STOP control sig-
nals.
