•Store within an ambient temperature range of -40° to +85°C.
•Store within a relative humidity range of 0% to 95%, non-condensing.
•Do not expose to a corrosive atmosphere.
AC Supply Source Considerations
Ungrounded Distribution Systems
ATTENTION: HPVFE 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.
1. Turn the screw counter clockwise to loosen.
2. Pull the jumper completely out of the drive chassis.
3. Tighten the screw to keep it in place.

Important: Tighten screw after jumper removal.
