Ungrounded Power Configurations
Ungrounded power configurations are allowed, but you must jumper across a
120 k
Ω resistor (internal to the IAM power module) to prevent high
electrostatic build-up. The ungrounded power configuration (shown below) does
not provide a neutral ground point. The IAM power module has a ground
jumper set for grounded power distribution (default configuration).
Figure 49 - Ungrounded Power Configuration
Refer to Appendix A on
, 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 to prevent
electrostatic buildup inside the IAM power module.
Refer to Setting the Ground Jumper in Ungrounded Power Configurations on
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.
