Passive Shunt Considerations
The 2198-Pxxx DC-bus power supplies all include an internal shunt that is
wired to the shunt resistor (RC) connector at the factory. Bulletin 2198-Rxxx
external passive shunts are available to provide additional shunt capacity for
applications where the internal shunt capacity is exceeded.
Catalog numbers 2198-R014, 2198-R031, and 2198-R127 are composed of resistor
coils that are housed inside an enclosure. Catalog number 2198-R004 is a shunt
resistor without an enclosure.
Figure 18 - External Passive Shunts
How the Bulletin 2198-Rxxx shunts connect to the 2198-Pxxx DC-bus power
supply is explained in External Passive-shunt Connections
on page 172 and
illustrated with interconnect diagrams in Passive Shunt Wiring Examples
on
page 337
.
IMPORTANT
Keep the DC-bus power supply internal shunt wires connected unless
you have an external passive shunt to connect.
IMPORTANT
2198-RPxxx regenerative bus supplies do not support passive shunts.
The active shunt (RC) connector is used for making active shunt
connections.
