Power cable connection at the drive output from above (option M78)

The motor-side power cables can be introduced into the cabinet from the top.
3.6.40

Capacitor release (option N20)

Option N20 can be used for circuit-breakers with control voltages of 110 – 120 VDC.
Note
Circuit diagrams
Also use the circuit diagrams MA sheet 1 and LA sheet 6 and 7 provided in the circuit manual
of the drive to understand the principle of operation.
The capacitor release is used for circuit-breakers that have a break time of 80 ms but do not
have an undervoltage release.
If the control voltage for the switchgear fails, the drive circuit-breaker is deactivated by the
energy stored in the capacitors of the capacitor release. The circuit-breaker is also deactivated
when a control voltage is present if the output voltage of the capacitor release or drive control
voltage fails. The OFF command is sent to the circuit-breaker via two redundant circuits.
