Ungrounded Power Configurations
Ungrounded power configurations are allowed, but you must jumper
across a 120 k
Ω
resistor (internal to the IAM) to prevent high
electrostatic build-up. The ungrounded power configuration (shown
below) does not provide a neutral ground point. The IAM has a
ground jumper set for grounded power distribution (default
configuration).
Ungrounded Power Configuration
IMPORTANT
If you determine that you have ungrounded 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.
Refer to Setting the Ground Jumper in Ungrounded Power
Configurations on page 75 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.
