ATTENTION: The sheet metal cover and mounting screws on the ASIC
Board located on the power structure are energized at (-) DC bus potential
high voltage. Risk of electrical shock, injury, or death exists if someone
comes into contact with the assembly.
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.

What You Need to Do
Complete the appropriate steps depending upon whether you are replacing a
main fan capacitor on a converter or inverter unit.
Step: 1 Remove Power
from the Drive
1. Turn off and lock out input power. Wait fifteen minutes.
2. Verify that there is no voltage at the drive’s input power terminals.
3. Check the DC bus voltage at the Power Terminal Block by measuring
between the +DC and -DC terminals, between the +DC terminal and the
chassis, and between the -DC terminal and the chassis. The voltage must
be zero for all three measurements.

ATTENTION: To avoid an electric shock hazard, verify that the voltage on
the bus capacitors has discharged before performing any work on the
drive. Check the DC bus voltage at the Power Terminal Block by measuring
between the +DC and -DC terminals, between the +DC terminal and the
chassis, and between the -DC terminal and the chassis. The voltage must
be zero for all three measurements.
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.

Step: 2 Remove the
Protective Covers
1. If you are replacing the fan capacitor on an inverter unit for an AC input
drive, skip this step and continue with step 2 below. If you are replacing the
fan capacitor on a converter unit or an inverter unit for a DC input drive,
complete the following steps:
a. For DC input drives with a precharge interlock, disconnect the input
wiring to the X50 terminal block on the control frame.
b. Loosen the two hexalobular screws that secure the control frame to the
enclosure and swing the control frame away from the converter unit.
2. Remove the four hexalobular screws that secure the air flow plate to the
drive enclosure and slide the plate off the drive.

Replacing the Fan Capacitor on the Inverter Unit
1. If you are replacing a fan capacitor on a PowerFlex 700H drive inverter
unit, continue with step 2 on page 12. For PowerFlex 700S drives, if you
are replacing the fan capacitor on the V phase of the inverter unit,
complete steps a.…c.
a. Disconnect the bus connection cable from connector J2 and the motor
feedback connection cable from connector J1 on the voltage feedback
board.
b. Disconnect the fiber-optic cables from connectors J4 and J5 on the
voltage feedback board.
c. Remove the four POZIDRIV screws that secure the voltage feedback
board assembly to the fan housing and remove the assembly. Tightening
torque for re-assembly is 1.35 N•m (12 lb•in).
IMPORTANT Minimum inside bend radius for fiber-optic cable is 50 mm
(2 in.). Any bends with a shorter inside radius can
permanently damage the fiber-optic cable. Signal
attenuation increases with decreased inside bend radii.
