Input Power Configurations
for Kinetix 5700 Power
Supplies
The Kinetix 5700 drive system power supply can be either the 2198-Pxxx
DC-bus power supply or the 2198-RPxxx regenerative bus supply. The input
power components and wiring depend on which power supply is used.

DC-bus Power Supply

Before wiring input power to your 2198-Pxxx DC-bus power supply, you must
determine the type of input power within your facility. The drive modules are
designed to operate in both grounded and ungrounded environments.
IMPORTANT For IEC 61800-3 category C3 compliance, use the appropriate 2198-DBRxx-F
Grounded Power Configurations
The grounded (WYE) power configuration grounds your three-phase power at
a neutral point. This type of grounded power configuration is preferred.

(1) When using 2198-DBxx-F line filter, 2198-Pxxx power supply has the ground jumper installed and 2198-xxxx-ERSx inverters
have the ground jumpers installed.
When using 2198-DBRxx-F line filter, 2198-Pxxx power supply has the ground jumper installed, 2198-xxxx-ERSx inverters have
the ground jumpers removed.
ATTENTION: The 2198T-W25K-ER (iTRAK) power supply must receive DC-bus
voltage from a grounded-wye power configuration.

Connect the Kinetix 5700 Drive System
line filter with a grounded WYE configuration. The use of a line filter in an
ungrounded, corner-grounded, or impedance-grounded configuration can
affect the line filter components and result in equipment damage.
2198-DBxx-F line filters also provide compliance, but are not the preferred
solution because they require inverter ground jumpers installed manually.
