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.
• UL-conform with following fuses: Category "ClassCC", slow-blow.
