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
