10.6.5.1. Location of safety switches

Each primary and each secondary PCU is equipped with a safety switch. The safety
switches block and release the locking bars, depending on whether or not the drive
is 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.
