Ground Screw/Jumper
Settings
Determine the ground screw/jumper setting for your Kinetix 5700 drive
system power supply, iTRAK power supply, and Kinetix 5700 inverters.
Kinetix 5700 Drive System Power Supply
The Kinetix 5700 drive system power supply can be either 2198-Pxxx DC-bus
power supply or 2198-RPxxx regenerative bus supply.
DC-bus Power Supply
The 2198-Pxxx DC-bus power supply has a factory-installed ground screw for
grounded-wye power distribution. Table 65
summarizes the ground screw/
jumper settings for the 2198-Pxxx DC-bus power supply.
Regenerative Bus Supply
The 2198-RPxxx regenerative bus supply includes a factory-installed ground
jumper for grounded-wye power distribution. Table 66
summarizes the
ground jumper settings for the 2198-RPxxx regenerative bus supply.

Remove ground screw/jumper
IMPORTANT
If you have grounded-wye power distribution in your facility, do not
remove the ground screw from the DC-bus power supply. Remove the
ground screw when using ungrounded, corner-grounded, or impedance-
grounded power.

Remove ground jumper
(1)
(1) When the regenerative bus supply ground jumper is removed, it can be permanently stored in threaded holes at the bottom of
the chassis.
IMPORTANT
If you have grounded-wye power distribution in your facility, or corner-
grounded or ungrounded power with an isolation transformer, do not
remove the ground jumper from the regenerative bus supply. Remove
the ground jumper when using impedance-grounded power.
