Summary of Changes
This publication contains new and updated information as indicated in the following table.
PowerFlex® 750-Series drives contain protective MOVs (metal-oxide varistors) and Common Mode Capacitors referenced to ground. To guard
against unstable operation and/or damage, the drive must be properly configured as shown in the tables on page 3.

ATTENTION: The following information is merely a guide for proper installation. Rockwell Automation cannot assume responsibility for the compliance or the
noncompliance to any code, national, local or otherwise for the proper installation of this drive or associated equipment. A hazard of personal injury and/or
equipment damage exists if codes are ignored.

Power Jumper Configuration
ATTENTION: Allow only qualified personnel familiar with adjustable frequency AC drives and associated machinery to plan or implement the installation, start-
up, and subsequent maintenance of the system. Failure to comply can 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 completely before removing/installing jumpers.
Frames 1…7
Measure the DC bus voltage at the following points (see the PowerFlex 750-Series AC Drive Installation Instructions, publication 750-IN001 for locations):
• Measure the DC bus voltage at the power terminal block by measuring between the +DC and -DC terminals or between the +DC and -DC test point sockets if
equipped.
• Also measure between the +DC terminal or test point and the chassis, and between the -DC terminal or test point and the chassis.
The voltage must be zero for all three measurements.
Frames 8…10
Measure the DC bus voltage at the DC+ and DC- TESTPOINT sockets on the front of the power module (see Installation Instructions for location).
ATTENTION: This drive contains ESD (Electrostatic Discharge) sensitive parts and assemblies. Static control precautions are required when installing, testing,
servicing or repairing this assembly. Component damage can result if ESD control procedures are not followed. If you are not familiar with static control
procedures, reference an applicable ESD protection guide.
ATTENTION: Risk of equipment damage exists. The drive power source type must be accurately determined. Jumpers PE-A, PE-A1, PE-A2, and PE-B must be
configured for the power source type according to the recommendations shown in the following table.

To connect or disconnect these devices, refer to pages 5…7.
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, 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.
Recommended Power Jumper Configurations – Frames 1…7
Power Source Type Jumper PE-A (1) (2)
(MOV / Input Filter Caps)
(1) When MOVs are disconnected, the power system must have its own transient protection to maintain known and controlled voltages.
(2) Frame 5…7 Common DC Input drives do not have the PE-A jumper.
Jumper PE-B
(DC Bus Common Mode Caps) Benefits of Correct Configuration on Power Source Type
Non-solid Ground
• AC fed ungrounded
• Impedance grounded
• B phase ground
• DC fed from an active
converter
Disconnected Disconnected Helps avoid severe equipment damage when ground fault occurs.
Solid Ground
• AC fed solidly grounded
• DC fed from passive rectifier,
which has a solidly grounded
AC source
Connected Connected Reduced electrical noise, most stable operation, EMC compliance, reduced voltage stress on components
and motor bearings.

Jumper Installation, Removal, and Storage
Jumper screws (Frames 2…5), wires (Frames 1, 6 & 7), or plugs (Frames 8…10) are used to complete an electrical
connection when installed/connected. When power jumper screws are not used, they are stored on the left interior
chassis wall as shown.
When installing a jumper screw or wire, note the recommended torque listed.
Drive Identification
The ‘Voltage Code’ and ‘Default Power Jumper Configuration’ are on the drive nameplate. Use this information to
perform the proper procedure in the following tables.
ATTENTION: Hazard of equipment damage exists if jumpers are not properly disconnected.
For Frames 2…5, completely remove the jumper screw from the circuit board.
Frames 1, 6 & 7, secure the disconnected jumper wire to the standoff provided.
Frames 8…10 drive assemblies, secure the disconnected jumper plug in the socket that is provided and verify that all drive assemblies are identically configured.
