When installed on the input side of the AC Drive, line reactors will reduce line notching, and limit current
and voltage spikes and surges from the incoming line. The line reactors will also reduce harmonic
distortion from the AC Drive onto the line. Units are installed in front of the AC Drive as shown.

When installed on the output side of the AC Drive, line (load) reactors protect the drive from short circuits
at the load. Voltage and current waveforms from the drive are enhanced, reducing motor overheating and
noise emissions.

Single-phase line reactors should NOT be installed on the output of the AC Drive. Use only three-
phase reactors on drive outputs, and only for three-phase motors.
If installing a line reactor on the output side of the drive, especially with motor lead lengths in
excess of 75 feet, lower the drive PWM output carrier frequency to 4kHz in order to protect the line
reactor from excess heating and possible damage.
