Kinetix 5700 Regenerative Bus Supply
Ground Jumper Settings
The regenerative bus supply includes a ground jumper that is installed at the factory. Keep the
ground jumper installed when input power has a grounded-wye configuration. Remove the
ground jumper when using impedance-grounded power configurations. Refer to the
Kinetix 5700 Servo Drives User Manual, publication 2198-UM002, for configuration diagrams.
IMPORTANT
ATTENTION: Risk of equipment damage exists. The input-power ground configuration must be
accurately determined. When the ground jumper is installed with impedance-grounded power
distribution or when the ground jumper is not installed with grounded-wye power distribution,
damage to equipment can result.
ATTENTION: Risk of equipment damage exists. If you are using the 2198-RP
supply, always remove the ground jumper in 2198-D -ERS and 2198-S -ERS inverters.
ATTENTION: To avoid personal injury, the ground jumper access door 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.
The ground-jumper access door is located on the front of the regenerative bus supply. To access
the ground jumper, insert a small screw driver or probe into the door release slot and push the
door up behind the cover.
Remove the Ground Jumper

If you have grounded-wye power distribution in your facility, do not remove the ground
jumper from the regenerative bus supply. For all other power distribution configurations,
refer to the Kinetix 5700 Servo Drives User Manual, publication 2198-UM002, to determine
the ground jumper setting.
