With the exception of EMI filters, RF filters, and LR series line reactors, each accessory part number begins
with GS, followed by the AC Drive rating, and then the relevant accessory code. Following the accessory
code, you will find a description code when applicable. The diagram below shows the accessory part
numbering system.

Input line reactors protect the AC drive from transient overvoltage conditions typically caused by utility
capacitor switching. Input line reactors also reduce the harmonics associated with AC drives, and are
recommended for all installations.
Output line (load) reactors protect the motor insulation against AC drive short circuits and IGBT reflective
wave damage, and also allow the motor to run cooler by “smoothing” the motor current waveform. They
are recommended for operating “non-inverter-duty” motors, and for any motors when the length of wiring
between the AC drive and motor exceeds 75 feet.
There are two types of AutomationDirect line reactors that can be used with GS1 AC Drives; the original GS
series reactors (legacy) and the newer LR series reactors.
LR series reactors have universal mounting feet with multiple mounting slots, and they can replace most
reactors using the existing mounting holes. Use four bolts to mount the reactors to the mounting panel.
