3.6. Door locking system
To ensure safety and to prevent the doors being opened unintentionally, all doors
are lockable. The doors of compartments where medium voltages are present
during operation (2 and 3 in Fig. 3
14) are electro-mechanically secured.
Additionally, the doors of the medium voltage compartments have locks with
different inserts than the control compartment door. The different lock inserts
ensure that these doors can only be opened by personnel authorized to do so.

3.6.1. Optional cabinets
If medium voltages are present in an optional cabinet during operation (eg,
braking chopper and output disconnector), the door is secured by an electro-
mechanical lock as well as a door monitoring switch. If the cabinet is UL certified,
the door is further secured with extra screws. The lock and the switch release the
door after the DC link of the drive has discharged and the drive has been grounded.
