Figure 40 - Grounded Power Configuration (single-phase input)
(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.
Refer to Power Wiring Examples beginning on page 194 for input power
interconnect diagrams.
Ungrounded Power Configurations
The ungrounded power configuration (Figure 41), corner-grounded
(Figure 39
), and impedance-grounded (Figure 38) power configurations do
not provide a neutral ground point.

IMPORTANT To reduce leakage current in single-phase AC input operation, remove the
AC ground screw (refer to Figure 42
on page 79).
Install the AC ground screw only if higher EMC performance is required.
IMPORTANT If you determine that you have ungrounded, corner-grounded, or
impedance-grounded power distribution in your facility, you must remove
the ground screws in each of your drives that receive input power.
Refer to Remove the Ground Screws in Select Power Configurations
on
page 79
for more information.
