Where this Option is Used 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.
