When installed on the input side of the GS4 drive, a line reactor will reduce line notching, current
peaks, voltage spikes and surges from the incoming line, as well as reduce the available short
circuit current. A line reactor will also reduce harmonic distortion from the GS4 drive onto the line.
The line reactor is installed in front of the GS4 drive as shown.

When installed on the output side of the GS4 drive, line (load) reactors help to protect the GS4
drive from short circuits at the load. Voltage and current waveforms from the GS4 drive are
enhanced, reducing motor overheating and noise emissions.
GS4 Drive
Please refer to "Chapter 2: Installation and Wiring" for detailed wiring information for the GS4 drive.
Single phase line reactors should NOT be installed on the output side of an AC Drive. Use only
three-phase reactors on drive outputs, and only for three-phase motors.
