Multiple AC Drives
Individual line reactors are recommended when installing multiple AC Drives on the
same power line. Individual line reactors eliminate cross-talk between multiple AC
Drives and provide isolated protection for each AC Drive for its own specific load.
Multiple Motors
A single output (load) reactor can be used for multiple motors on the same AC
Drive, but only if the motors operate simultaneously. Size the reactor based upon
the total horsepower of all the motors, and select a reactor with a current rating
greater than the sum of the motor full-load currents. Overload relays are
recommended for use in multi-motor applications.
A single reactor should be used with multiple motors ONLY when the motors will
operate simultaneously from a single AC drive. OVERLOAD RELAYS are recommended
for use in multiple motor applications.
