Control Power Tests

Prior to energizing the drive, verify that the control power being
fed into the input breakers are rated as designated on the
electrical diagram.


Although there are a variety of options available to customers
that will effect the control power distribution within the drive,
the input will always be as illustrated below:

Three Phase Fan Power


Three phase voltage for the “A” frame cooling fan comes from the
medium voltage feed on the load side of the input contactor. On
isolation transformer drives, the fan power is tapped off the
transformer secondary. On line reactor drives, the fan power is
supplied by a separate medium voltage/low voltage transformer.
