AC Supply Considerations

for Bulletin 284E Units

Ungrounded and High Resistive Distribution Systems

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 24, Jumper Removal.

1. Before installing the Bulletin 284E, loosen four mounting screws.

2. Unplug control module from the base unit by pulling forward.

ATTENTION: The Bulletin 284E contains protective Metal Oxide

Varistors (MOV)s that are referenced to ground. These devices

should be disconnected if the Bulletin 284E is installed on an

ungrounded and high resistive distribution system.
