Ungrounded Power Configurations
The ungrounded power configuration (Figure 50) does not provide a neutral
ground point. Ungrounded, impedance-grounded, and corner-grounded
power configurations are allowed, but you must move a jumper (internal to the
IAM power module) across a 120 kΩ resistor. The IAM power module ground
jumper (default configuration) is set for grounded power distribution.
Figure 50 - Ungrounded Power Configuration
Refer to Appendix A on page 231, for input-power interconnect diagrams with
and without the LIM module.
IMPORTANT If you determine that you have ungrounded, impedance-grounded, or
corner-grounded power distribution in your facility, you must move the
ground jumper (configured for grounded power) to the ungrounded power
position inside the IAM power module.
Refer to Set the Ground Jumper in Select Power Configurations on page 97
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.
