7.4 Set Voltage on Internal Power Supply Transformer
The output voltage of the internal power supply transformer must match the input voltage of the
inverter's internal power supply. To do this, adapt the primary and secondary sides of the internal
power supply transformer to the inverter.
Figure 9: Position of connecting terminal plates
1. Set the input voltage on the primary side. This adjusts the output voltage to the inverter's input
voltage (see circuit diagram for the Transformer Compact Station).
2. Set the output voltage on the secondary side. This adjusts the output voltage to the inverter's
input voltage (see circuit diagram for the Transformer Compact Station).
