must be returned to the factory for modification.
DP power supplies are optionally available to operate on 380 V or 480 V, 3ö, 50 to 400 Hz
mains. For conversion from 380 V to 415 V or from 480 V to 440 V operation, two internal
wiring changes must be made to each power module. The locations are not accessible to the user
and the power supply must be returned to the factory for modification.
