Where this Option is Used

The 1204 Reﬂected Wave Reduction Device (RWR2) is designed to be

used with Allen-Bradley 1305 and 160 AC Drives. 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.

Catalog Number Explanation

Same footprint size as corresponding 1305 Frame. See page 3 for details.

1204 Reflected Wave Reduction Device 1. Assure that all power has been removed from the drive. Mounting 2. Determine the best mounting location for your device style. The device must be mounted on a vertical metal surface and oriented so the wiring knockouts are on the bottom – The device must be mounted within 3.0 meters (10 feet) of the drive. The 160 AC Drive may not be mounted on top of the RWR2 in the “Stack” configuration.
