Regenerative Bus Supply

Before wiring input power to your 2198-RPxxx regenerative bus supply, you
must determine the type of input power within your facility. The regenerative
bus supply is designed to operate in grounded-wye and impedance grounded
environments. Corner-grounded and ungrounded power can be used, but you
must add an isolation transformer to the input power circuit to provide
grounded-wye power.
ATTENTION: For IEC 61800-3 category C3 compliance, use the appropriate
2198-DBRxx-F AC line filter with a grounded WYE configuration. Use of the
AC line filter in an ungrounded or corner-grounded configuration (without
an isolation transformer) or in an impedance-grounded configuration can
affect the line filter components and result in equipment damage.
2198-DBxx-F line filters are not compatible with regenerative bus supplies.
Grounded Power Configurations
This grounded (WYE) power configuration
phase input power at a neutral point. This is the preferred grounded power
configuration.

ATTENTION: The 2198T-W25K-ER (iTRAK) power supply must receive DC-bus
voltage from a grounded-wye power configuration.
