Adjusting the internal power supply (-A1-T10)

A transformer is installed in the line connection module (-A1-T10) for the internal 230 V AC
power supply for the cabinet. The location of the transformer is indicated in the layout
diagrams supplied.
When delivered, the taps are always set to the highest level. The primary terminals of the
transformer may need to be reconnected to the existing supply voltage.
The supply voltage assignments for making the appropriate setting on the transformer for the
internal power supply are indicated in the following tables.
NOTICE
If the terminals are not reconnected to the actual supply voltage, the internal power supply
will not be correct.
