* Chokes are necessary only for special applications, e.g. quiet motor operation
(stage technique)
Switching in the armature circuit
- dc circuit current-free
- disable inactive
Warning
:
Faulty switching will create arcing across the switch contacts.
Power supply failure - brake resistor
Break contact of the mains contactor K1
Rating:
Resistor RNB = max. armature voltage/2 x type current
Attention:
Power lines have to be shielded and routed separately from control lines!
For electro-magnetic interferences please refer to the CE advice.
