PowerFlex 70 Power Jumpers
Installation Instructions
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 .

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: 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.

Disconnected Disconnected
It is highly recommended to accurately determine the power source type and then configure appropriately.
When MOVs are disconnected, the power system must have its own transient protection to ensure known and controlled voltages.
To connect or disconnect these devices, refer to pages
4 and
5 .
Important: Common mode capacitors are used to conform with the EMC directives. Removing these devices may withdraw the associated directive.

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 on a non-solid ground power source.
To verify: an extra “R, S, T” terminal block will be present if the option is installed (as shown).
Additionally, the 13th character of the nameplate catalog number will be an “A” (see
