AC supply source considerations
Ungrounded Distribution Systems
ATTENTION: ILVFE drives contain protective MOVs that are referenced to ground.
These devices must be disconnected if the drive is installed on an ungrounded or
resistive grounded distribution system.
Disconnecting MOVs
To prevent drive damage, the MOVs connected to ground shall be disconnected if the drive is installed
on an ungrounded distribution system where the line-to-ground voltages on any phase could exceed
125% of the nominal line-to-line voltage. To disconnect these devices, remove the jumper shown in
the Figures 1.1 and 1.2 below
1. Turn the screw counterclockwise to loosen.
2. Pull the jumper completely out of the drive chassis.
3. Tighten the screw to keep it in place.

Figure 1.2 Phase to Ground MOV Removal
Important: Tighten screw after jumper removal.
