AC890PX AC Drive
2.1.7 Auxiliary Transformer Taps (C)
The transformer is tapped for no connection, i.e. 0V - PARK when
it leaves the factory and the drive will not operate. Either a low
voltage or high voltage transformer option is fitted to the drive.
Match the auxiliary transformer tap to the drive's nominal supply
voltage. For example, connect the taps to 0V and 400V for a
nominal supply voltage of 400Vac.
The transformer supplies a constant 30Vac to the Control Module,
internal fans etc. It is protected by a 40A semi-conductor fuse
