Regenerative Bus Supply Configurations With Active Shunt Chapter 5
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.
Shunt Connections
Figure 31 - RC Connector Wiring
You can make active shunt connections in drive systems that include the regenerative bus supply and Powerohm PKBxxx-800 or
PWBxxx-800 active shunts at the external DC-bus studs on accessory modules.
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.
IMPORTANT 2198-RPxxx regenerative bus supplies do not support passive shunts. Make active shunt connections to the 2198-RPxxx
regenerative bus supply at the active shunt (RC) connector or the external DC-bus studs on accessory modules, depending on the
shunt type.

IMPORTANT Due to the 10 A connector current rating, connections to the RC connector are limited to only Powerohm PKBxxx-xxx active shunts
rated at 7 kW or less. All other PKBxxx-xxx and PWBxxx-xxx active shunt connections must be made to the 2198-CAPMOD-2240
capacitor module.
