Selecting/Verifying Control
Transformer Voltage
The control transformer is located inside the upper right part of the drive
assembly and is typically set to match the input line voltage. The control
transformer provides the single-phase 240V internal control voltage, power for
the drive blower, and the enclosure fans. If the line voltage is different than the
voltage class specified on the drive nameplate, it may be necessary to change
transformer taps. To gain access to the transformer, refer to the PowerFlex 750-
Series Hardware Service Manual, publication 750-TG001.
