4.6.4 Adjusting the Internal Power Supply (-A1 -T10, Only with
Version A)
A transformer is installed for the internal power supply of the cabinet. The location
of the transformer is indicated in the layout diagrams supplied.
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 table.
IMPORTANT
If the terminals are not reconnected to the actual supply voltage, the internal power
supply will not be correct.
