Set the Ground Jumper in
Select Power Configurations
Setting the ground jumper is necessary when using an ungrounded, corner-
grounded, and impedance-grounded power configuration. Also, set the ground
jumper when you are using the 8720MC regenerative power supply, or any active
converter, for DC-bus voltage. Setting the ground jumper involves accessing the
power chassis and removing jumper plugs or disconnecting wires on the power
terminals.
Table 32 - Ground Jumper Configurations
Table 33 - Jumper/Wire Location and Removal Instructions
ATTENTION: To avoid personal injury, the ground jumper access area must be
kept closed when power is applied. If power was present and then removed,
wait at least 5 minutes for the DC-bus voltage to dissipate and verify that no DC-
bus voltage exists before accessing the ground jumper.
Because the unit no longer maintains line-to-neutral voltage protection, risk of
equipment damage exists when you remove the ground jumper.

Common mode capacitor Remove DC-DC converter and drive top cover, and disconnect the green/
yellow wire from the drive chassis. Insulate and secure the wire to prevent
unintentional contact with the chassis or components. See Remove the
Ground Wires on 2099-BM09-S and 2099-BM10-S Drives on page 79.
MOVs/input filter cap Disconnect the green/yellow wire next to the power terminal block. Insulate
and secure the wire to prevent unintentional contact with the chassis or
components. See Remove the Ground Wires on 2099-BM09-S and 2099-

Green/yellow
wire
Common mode capacitor Disconnect the two green/yellow wires from the PE terminals on the power
terminal block. Insulate and secure each of these wires to prevent
unintentional contact with the chassis or components. See Remove the
Ground Wires on 2099-BM11-S and 2099-BM12-S Drives on page 79.
