Regenerative Bus Supply Configurations Chapter 4
PowerFlex 750-Series drives contain protective metal-oxide varistors (MOV) and common mode capacitors referenced to ground. To guard
against unstable operation and/or damage, the drive must be properly configured as shown in the following table.
For instructions on how to disconnect the PE jumpers, refer to PowerFlex 750-Series Power Jumpers Installation Instructions, publication
750-IN011
.
Kinetix 5700 Regenerative Bus Supply Considerations
When extending the DC-bus from the power supply cluster, a capacitor module must be used to extend the bus. Refer to Kinetix 5700
Accessory Modules on page 71 for more information on when accessory modules are required.
Bus Supply Ground Jumper Setting
The 2198-RPxxx regenerative bus supply has a factory-installed ground screw for grounded-wye power distribution. The following table
summarizes the ground screw/jumper settings for the 2198-RPxxx regenerative bus supply.

IMPORTANT Regenerative bus supplies do not require an isolation transformer for three-phase input power unless they are connected to
corner-grounded or ungrounded facility power.

(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.
