3.8.2. Locking bars

A locking bar is a safety mechanism that locks the doors of the primary and secondary PCUs
when the drive is ungrounded.
You can only slide the locking bar (1, Fig. 24) to the unlocked position (2, Fig. 24) and open the
doors when the drive is grounded, ie, when the white lamp (3, Fig. 24) is lit. In order to slide a
locking bar to the locked position (4, Fig. 24), you need to close all of the PCU doors (2 doors in
1700 mm PCUs, 3 doors in 2100 mm PCUs).
