The 1204 Reflected Wave Reduction Device with Common Mode Choke
(RWC) is designed to be used with Allen-Bradley 1336 family of AC drives
with compatible current ratings. Call factory for advice on using the
1204-RWC with drives other than the 1336 family of AC drive. When
installed near the drive, the device can reduce potentially destructive
reflected wave spikes that can occur with long motor leads and reduces the
effect of Common Mode noise.

Altitude Derating Above 1000 meters (3300 feet) derate at 6% of RWC rated amperes per 1000 meters (3300

feet) elevation to 4000 meters (13200 feet) maximum.

Heat Dissipation Use the cable length and drive carrier frequency to find the approximate RWC losses for your

system. Vertical movement inside the loss band will be dependent on exact cable type and
motor load.
