Transformer (-T11) for generating the auxiliary voltage 230 V AC

A transformer is incorporated to generate the 230 V AC, 2-phase voltage. This voltage is
made available in order to supply the auxiliary voltage busbar and the SITOP power supply.
When delivered, the taps are always set to the highest level. The line-side terminals of the
transformer may need to be reconnected to the existing line voltage.
The line voltage assignments for making the appropriate setting on the transformer for the
internal power supply are indicated in the following table.
NOTICE
The terminals must be reconnected to the actual line voltage so that the 230 V AC, 2-phase
voltage required in the system is provided correctly.
Reconnect the terminals only when the cabinet unit is disconnected from the power supply.
