10.6.5.1. Location of safety switches

To prevent you from opening the medium voltage compartment doors during operation, each
primary and secondary PCU has a safety switch. The switch blocks and releases the locking bar
based on the drive being discharged and grounded. This prevents doors from being opened
unintentionally during operation.
In 1700 mm PCUs, the safety switches are on the back of the left door.
In 2100 mm PCUs, the safety switches are on the back of the middle door.
A screw cap on the front of the door marks the exact position.
Key:
(1) Safety switch behind door

NOTE – For the safety switches to work and to be able to open the doors, auxiliary power supply
is required. If the auxiliary power supply is unavailable and the doors are closed, you can only
open them by unlocking the safety switch manually.
