Accessories Part Numbering
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.
GS Series-specific Part Number Explanation
Line Reactors
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
DURA
PULSE GS3 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.
