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)

(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.

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.
