Connection of the Power Circuit
Wiring diagram 3
1
Supply fuse
2
Disconnect switch or contactor
3
Line choke
4
Interference suppression filter
External motor temperature sensor
(for all units)
Don't install sensor wires with control wires!
Must use double shield when running these
wires with motor wires!
It is necessary to activate this function via
software parameter! See US.33
Connection of braking resistor
(Braking circuit installed as standard in
housing sizes E,G,H, R and U.)
Braking resistor
with line side over
temperature cutoff

This is the only way to turn
off voltage to the resistor in
the event of failure of the
internal braking transistor of
the inverter.
