Ungrounded Power Configurations
The ungrounded power configuration ( Figure 59 ), corner-grounded
( Figure 58 ), and impedance-grounded ( Figure 57 ) power configurations do
not provide a neutral ground point.
Figure 59 - Ungrounded Power Configuration
Refer to Power Wiring Examples beginning on page 279 for input power
interconnect diagrams.
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 DC-bus power supplies and iTRAK power
supplies and install the ground screw/jumper in each of your dual-axis and
single-axis inverters.
Refer to Ground Screw/Jumper Settings on page 96 for more information.

ATTENTION: Ungrounded systems do not reference each phase potential to
a power distribution ground. This can result in an unknown potential to earth
ground.
