Installation Instructions
PowerFlex 750-Series Power Jumpers
PowerFlex 750-Series drives contain 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 1 on
page 2.
For additional general information, refer to:
Before proceeding, ensure that all power to the drive has been removed.

Wiring and Grounding Guidelines for PWM AC Drives DRIVES-IN001
Guarding Against Electrostatic Damage 8000-4.5.2
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 may result if ESD control procedures are not followed. If you are
not familiar with static control procedures, reference A-B publication
8000-4.5.2, “Guarding Against Electrostatic Damage” or any other
applicable ESD protection guide.
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: 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
during installation.

Table 1 - Recommended Power Jumper Configurations
To connect or disconnect these devices, refer to pages 4…6.
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.
ATTENTION: To avoid an electric shock hazard, verify that the voltage on
the bus capacitors has discharged completely before removing/installing
jumpers.
Frames 2…7
Measure the DC bus voltage at the following points (refer to the
Installation Instructions for locations):
• +DC and -DC terminals of the Power Terminal Block
• +DC terminal of the Power Terminal Block and the chassis
• -DC terminal of the Power Terminal Block and the chassis
The voltage must be zero for all three measurements.
Frame 8
Measure the DC bus voltage at the DC+ and DC- TESTPOINT sockets on
the front of the power module (see Installation Instructions for location).
Power Source Type

(1) It is highly recommended to accurately determine the power source type and then configure appropriately.
MOV/Input
Filter Caps
(PE-A)
(2)(3)
(2) When MOVs are disconnected, the power system must have its own transient protection to ensure known and
controlled voltages.
(3) Frame 8 drives utilize two jumpers labeled PE-A1 and PE-A2.

IMPORTANT
Common mode capacitors are used to conform with the EMC
directives. Removing these devices may withdraw the associated
directive.

Jumper Installation, Removal and Storage
Jumper screws (Frames 2…5),
wires (Frames 6…7) or plugs
(Frame 8) 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
Refer to the drive nameplate and
locate the “Voltage Code” and
“Default Power Jumper
Configuration.” Use this
information to locate 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. On Frames 6…7, secure the disconnected
jumper wire to the standoff provided. On Frame 8, secure the disconnected
jumper plug in the socket provided and the PE-A1 jumper wire to the
standoff provided.
