ATTENTION: The Bulletin 284E contains protective Metal Oxide Varistors
(MOVs) that are referenced to a ground. These devices should be disconnected
if the Bulletin 284E is installed on an ungrounded and high resistive
distribution system.
ATTENTION: Do not remove this jumper, shown in Figure 23, if the unit is
equipped with an EMI filter installed.
