Allen-Bradley PowerFlex 70 User manual

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

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).
