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.
