Temporarily bypassing the interlock:
1. Shut down the drive
2. Turn off the main switch on the cabinet door (=D3-Q12)
Switching off the auxiliary supply de-energizes the main contactor or the circuit breaker.
3. Open the cabinet door.
4. Secure the power unit against reconnection
For systems with main contactor, switch off the power unit disconnector (=D3-Q11),
for systems with circuit breaker, interlock the circuit breaker (=D3-Q11)
5. Turn on the auxiliary supply
Attach a suitable tool (e.g. open-ended wrench with width across flats of 13 mm) to the
axle of the auxiliary incoming feeder circuit breaker and rotate it to ON position.
6. Carry out adjustment and parameterization work
7. Switch off the auxiliary supply
Attach a suitable tool (e.g. open-ended wrench with width across flats of 13 mm) to the
axle of the auxiliary incoming feeder circuit breaker and rotate it to OFF position.
8. Override the power module's lockout device
9. Close the cabinet door
Switch on
● Switch on the 400 V AC (460 V) auxiliary supply - Disconnector D3-Q12:
Close disconnector D3-Q12 with suitable mechanical aids when the doors are open.
● Switch on the armature supply - D3-Q11 (switch disconnector with fuses or motor
operated circuit breaker)
– For systems with a rated current of up to 850 A, bring the 3KL switch-disconnector
– For systems with a rated current of ≥950 A, bring the motor-tripped circuit breaker
