Ungrounded and High-impedance Grounded Power Configurations
Ungrounded and high-impedance grounded power configurations are allowed,
but you must jumper across a 120 k
Ω resistor (internal to the IAM module). The
ungrounded power configuration (shown below) does not provide a neutral
ground point. The IAM module has a ground jumper set for grounded power
distribution (default configuration).
Figure 41 - Ungrounded Power Configuration
Refer to Appendix A on page 187 , for input-power interconnect diagrams with
and without the LIM module.
IMPORTANT If you determine that you have ungrounded or high-impedance grounded
power distribution in your facility, you need to move the default jumper
(configured for grounded power) to the ungrounded power position inside the
IAM module.
Refer to Setting the Ground Jumper in Ungrounded Power Configurations on
page 87 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.
