Adapting the internal power supply (-T10, version A only)

A transformer (-T10) is installed in the Line Connection Module for the internal 230 V AC
power supply for 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 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 tables.
NOTICE
Faults can occur if the terminals are not reconnected to match the actual line voltage.
