Load switch-disconnector

The drive has a load switch-disconnector handle. In units without an optional load
switch-disconnector (+F253), the handle operates the internal switch-disconnector
contained within each supply module.
WARNING! The load switch-disconnector does not switch off the auxiliary voltages
inside the cabinet. In units without option +F253, the switch-disconnector does not
switch off the voltage at the input terminals of the supply module(s).
Note: On units without the line contactor option (+F250) and the load switch-
disconnector option (+F253), the supply unit will start rectifying as soon as the
switch-disconnector(s) within the supply module(s) is closed.

Auxiliary voltage switch

The auxiliary voltage switch controls the voltage supply to the auxiliary voltage
transformer.

Earthing/Grounding switch

An earthing/grounding switch for temporary grounding is optionally available.

Other door controls

The following switches are mounted on the door of the control and I/O cubicle:
Supply unit fault reset
button
Emergency stop button

transformers, ground fault supervision, motor fan
supply, and the voltage display of the DSSB board.
Operating switch (units with
main contactors only)
"START" position closes the
main contactors and the supply
unit starts rectifying. In the
"OFF" position, the main
contactors are open.
