Ungrounded Three-phase Power Configurations
Ungrounded power configurations are allowed, but you must jumper across a
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 Three-phase Power Configuration (delta secondary)
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 the Setting the Ground Jumper in Ungrounded Power
Configurations on page 69 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.
