Catalog Number Explanation
The 1204ReflectedWaveReduction Device(RWR2)is designed to be
usedwith Allen-Bradley1305and 160ACDrives.When installed near
the drive, the device can reduce potentially destructive reflected wave
spikes that can occur with long motor leads. The following table lists
the Allen-Bradley drives that are compatible with the RWR2.

Altitude Derating Above 1000 meters (3300 feet) derate at 6% of RWR2 rated
amperes per 1000 meters (3300 feet) elevation.
Heat Dissipation Use the cable length and drive carrier frequency to find the
approximate RWR2 losses for your system. Vertical movement
inside the loss band will be dependent on exact cable type and
motor load.
