Adapting the unit to the mains voltage

Factory settings upstream transformer
Fig. 25: Adapting the mains voltage on the upstream transformer
Units with a mains voltage of 400/460 V can be connected optionally to another mains voltage.
The mains voltage on the upstream 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 match the changed mains voltage, see the "Upstream fuse" column in
• 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 "Class CC", slow-blow, suitable for transformer protection.

NOTE
The changed mains voltage on the transformer must be marked on the yellow connection diagram (1) on the back of the unit.
