44 Rockwell Automation Publication 280E-UM001B-EN-P - July 2012
Chapter 2 Installation and Wiring
Disconnecting MOVs
To prevent drive damage, the MOVs connected to ground must be disconnected
if the drive is installed on an ungrounded and high resistive distribution system
where the line-to-ground voltages on any phase could exceed 125% of the
nominal line-to-line voltage. To disconnect the MOVs, remove the jumper shown
in Figure 23, Bulletin 284E Jumper Removal.
1. Before installing the Bulletin 284E, loosen four mounting screws.
2. Unplug control module from the base unit by pulling forward.
