In order to prevent any damage, the external protec-
tion circuit must switch off the motor in case the rotor
is blocked.
Turn on switching power for 30 s, recovery time until switching on again is 15 minutes.
For short-term switching operations, an impulse/pause ratio of 3 % must be considered.

Continuous and inching operation is not permitted.
In order to prevent any damage, the external protec-
tion circuit must switch off the motor in case the rotor
is blocked.

The power relays operate in interlocked mode, that is, only one relay of each switching pair picks up at a time
thereby avoiding a power-supply short circuit.
