.

On an ungrounded distribution system where the line-to-ground voltages on any
phase could exceed 125% of the nominal line-to-line voltage, install an isolation
transformer. See Wiring and Grounding Guidelines for PWM AC Drives,
publication DRIVES-IN001 for more information on impedance grounded and
ungrounded systems.

Drive Identification

Refer to the drive nameplate and locate
the “Voltage Code,” “Current Rating,”
and “Frame.” Use this information to
find the proper procedure in the
following tables.

Power Source Type

(1)

(1) It is highly recommended to accurately determine the power source type and then configure appropriately.

MOV/Input Filter
Caps

(2)

(2) When MOVs are disconnected, the power system must have its own transient protection to ensure known and controlled voltages.

Benefits of Correct Configuration on
Power Source Type

Solid Ground
AC fed, solidly grounded
DC fed from passive rectifier which has an AC

source and solid ground

Connected

Reduced electrical noise,
Most stable operation,
EMC compliance,
Reduced voltage stress on components

and motor bearings.

Non-Solid Ground
AC fed ungrounded
Impedance grounded
High resistive ground
B phase ground
Regenerative unit such as common DC bus

supply & brake

DC fed from an active converter

Disconnected

Helps avoid severe equipment damage

when ground fault occurs.
