8.3 Additional components
8.3.1 Transformers
General information
Transformers are only needed when the mains voltage is outside of the al‐
lowed nominal voltage of the drive controller.
Grounded mains
For grounded mains, the mains voltage is adjusted to the nominal voltage of
the device by means of autotransformers which have been sized for a specif‐
ic output voltage range.
Ungrounded mains
For voltage adjustment of ungrounded mains, always connect isolating trans‐
formers to prevent overvoltages between outer conductor and ground.
