Adapting the unit to the mains voltage
Factory settings control transformer
Fig. 16: Adapting the mains voltage on the control transformer
Units with a rated voltage of 400 / 460 V can be optionally connected to another mains voltage.
The mains voltage on the transformer must be adapted for this.
•
The adaption is made by replugging the supply cable on the primary side of the transformer.
•
The upstream fuse must correspond to the changed mains voltage, see column
•
The data for the transformer factory settings can be found on the yellow connection diagram (1) on the rear of the unit.
