Auxiliary power supply, 230 V AC (option K74)
Description
The auxiliary power supply provides the auxiliary voltages required for external control
circuits of the cabinet unit on the plant side.
Adapting the auxiliary power supply (-T10)
A transformer is installed in the Lne Connection Module (-T10) to produce the auxiliary
voltages of the cabinet unit. The location of the transformer is indicated in the layout
diagrams supplied.
When delivered, the taps are always set to the highest level. The line-side terminals of the
transformer may need to be reconnected according to the existing line voltage.
The tables below show the appropriate transformer setting for the control power supply
based on the existing line voltage.
