Publication 20A-IN010B-EN-P

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:

For additional general information, refer to:

Before proceeding, ensure that all power to the drive has been removed.

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.

Table A Recommended Power Jumper Configurations

To connect or disconnect these devices, refer to pages 4and 5.

Important: Common mode capacitors are used to conform with the EMC

directives. Removing these devices may withdraw the associated

directive.

!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. Measure the DC bus voltage at the following

points (refer to the User Manual for locations):

•+DC terminal of the Power Terminal Block and the -DC test point

(Frames A…D) or the -DC terminal of the Power Terminal Block

(Frame E)

•+DC terminal of the Power Terminal Block and the chassis

•-DC test point (Frames A…D) or the -DC terminal of the Power

Terminal Block (Frame E) and the chassis

The voltage must be zero for all three measurements.

!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.

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 Connected •UL compliance,

•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 Disconnected •Helps avoid severe equipment

damage when ground fault

occurs

Publication 20A-IN010B-EN-P

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. Most drives will have a

jumper storage area inside the front cover. Extra jumpers or jumpers that have

been removed should be stored in this location for use at a later time.

In some cases a protective cover may be present over the jumper pins that

extend from the board. If present, simply remove the protective cover, install (or

remove) jumper and replace cover.

Drive Identification

Refer to the drive nameplate and locate the “Voltage Code,” “Frame” and

“Internal EMC Option” (Frame B drives). Use this information to locate the

proper procedure in the following tables.

Important: The Internal EMC Filter (input filter)

is a factory installed option on Frame B drives. If

the option is installed, the drive cannot be used
