Capacitor Replacement Kit

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

Step: 1 Remove Power
from the Drive

PowerFlex 700H and 700S AC Drives Frame 9 Main Fan Capacitor Replacement Kit

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 DC+ & DC- terminals. The
voltage must be zero.

ATTENTION: Remove power before making or breaking cable
connections. When you remove or insert a cable connector with power
applied, an electrical arc may occur. An electrical arc can cause personal
injury or property damage by:

• sending an erroneous signal to your system’s field devices, causing

unintended machine motion

• causing an explosion in a hazardous environment

Electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance.

1. Turn off and lock out input power. Wait five minutes.

2. Verify that there is no voltage at the drive’s input power terminals.

3. Measure the DC bus voltage at the DC+ & DC- terminals on the power

terminal block. The voltage must be zero.

Step: 2 Remove the Lower
Protective Cover

Step: 3 Remove the
Existing Fan Capacitor

1. If necessary, remove the cables from the input power terminals (L1, L2 and
L3).

2. Remove the M4 x 8 mm POZIDRIV screw that secures the fan inverter
cover to the drive frame and remove the cover. Discard the existing fan
inverter cover and screw -- new parts are provided in the kit.

IMPORTANT

Mark all connections and wires before removing to avoid incorrect
wiring during reassembly.

3. Remove the fuses from the fuse holder.

4. Disconnect the four fuse signal wires (black and red pairs) connected to

the top and bottom of the fuse holder.

IMPORTANT

Note that the red wires connect to the left side terminal on the
fuse holder and the black wires connect to the right side
terminal on the fuse holder.

5. Disconnect the stirring fan power wires.

6. Remove the two M5 x 10 mm POZIDRIV screws that secure the fan
capacitor, fuse holder and fan bracket to the drive frame, and lift the
bracket out of the drive. Note that the fan capacitor is still connected to
the drive circuitry. Discard the two M5 x 10 mm screws -- new hardware is
provided in the kit.

7. Disconnect the capacitor wires from the connectors labelled “Blue” and
“Brown”.
