Emergency stop button
(optional)
Note: On units without the line contactor option (+F250), main breaker option
(+F255) or the main switch-disconnector option (+F253), the supply unit will start
rectifying as soon as the user closes the switch-disconnector(s) of the supply
module(s). There is no separate operating switch for the start on the cabinet door.

Control panel

There is one panel on the cabinet door which communicates with the inverter unit as
standard. However, the panel link is also wired to the control board of the supply
unit. You can change the communication from the inverter unit to the supply unit,
after which it is possible to:
• view and reset fault and warning messages, and view the fault history
• view actual signals
• change parameter settings
• change between the local and external control and, in the local control, start and
stop the supply unit.
For the instructions on the use of the panel, see the appropriate Firmware manual of
the drive application program. For details on the supply unit control program, see
ACS800 diode supply control program firmware manual
(3AUA0000068937[English]).

Analog and digital I/O signals

The diagram below shows the I/O signal connections of a standard diode supply
unit.
Note: The I/O setting is reserved for the internal use. Do not change the wiring.
Note: The I/O connections of the delivery may vary somewhat from what is
represented depending on which options are in use. Always refer to the circuit
diagram set delivered with the drive if in doubt of the applicability.
