Line lengths for the
drive circuit
The control inputs for starting and stopping are not rated for longer dis-
tances. This means:
• In the case of a drive circuit that goes beyond the control cubicle, cou-
pling relays must be used.
• The control cables in the cubicle should not be laid together with main cir-
cuit cables.
When electronic output modules are used in the drive circuit (e.g. Triac out-
puts at 230 VAC), RC elements (e.g. 3TX7462-3T or similar with C > 100 nF)
may be required at the control inputs under certain circumstances.
