Determine the Input Power
Configuration
Before wiring input power to your Kinetix 5500 system, you must determine
the type of input power within your facility. The drive is designed to operate in
both grounded and ungrounded environments.
Grounded Power Configurations
The grounded (WYE) power configuration lets you ground your three-phase
power at a neutral point. This type of grounded power configuration is
preferred.
Figure 37 - Grounded Power Configuration (WYE Secondary)
(1) When using 2198-DBxx-F line filter, the AC ground jumper is installed and the DC ground jumper is installed. When using
2198-DBRxx-F line filter, the AC ground jumper is installed and the DC ground jumper is installed.
The Kinetix 5500 drive has factory-installed ground screws for grounded (wye)
power distribution.
Refer to Power Wiring Examples
beginning on page 194 for input power
interconnect diagrams.
ATTENTION: Ungrounded, corner-grounded, and impedance-grounded
input power configurations are permitted, but you must remove the ground
screws. Refer to Ground Screw Settings
on page 78 for a ground screw
summary.
