The PowerFlex 70 drive contains protective MOVs and Common Mode

Capacitors referenced to ground (see below). To guard against unstable

operation and/or damage, the drive must be properly configured

as shown in

Table A on page 2

Important: All PowerFlex 70 drives are shipped with the DC bus common

mode capacitors referenced to ground.

The information in this document supersedes the MOV and Common Mode

Capacitor material in the following:

PowerFlex 70 Power Jumpers ! ! ATTENTION: Only qualified personnel familiar with adjustable frequency AC drives and associated machinery should perform maintenance/repair of the system. Failure to comply may result in personal injury and/or equipment damage. ATTENTION: To avoid an electric shock hazard, verify that the voltage on the bus capacitors has discharged before performing any work on the drive.

PowerFlex 70 Power Jumpers 3 In addition, on an ungrounded distribution system where the line-to-ground voltages on any phase could exceed 125% of the nominal line-to-line voltage, an isolation transformer should be installed. See Wiring and Grounding Guidelines for PWM AC Drives, publication DRIVES-IN001 for more information on impedance grounded and ungrounded systems. Jumper Installation, Removal and Storage PowerFlex 70 drives utilize plug-in style jumpers.
