ATT EN TI ON : Only qualified electrical personnel familiar with the construction
and operation of this equipment and the hazards involved should install, adjust,
operate, or service this equipment. Read and understand this procedure in its
entirety before proceeding.
ATT EN TI ON : Do not remove the existing filter capacitor assembly or install the
replacement kit with power applied to the drive. Disconnect, lock out, and tag
all incoming power to the drive enclosure before attempting such removal or
installation. Failure to observe this precaution could result in severe bodily
injury or loss of life.
ATT EN TI ON : DC bus capacitors retain hazardous voltages after input power has
been disconnected. After disconnecting input power, wait five (5) minutes for
the DC bus capacitors to discharge and then check the voltage with a voltmeter
to ensure that the DC bus capacitors are discharged before touching any internal
components. Failure to observe this precaution could result in severe bodily
injury or loss of life.
ATT EN TI ON : The user is responsible for conforming with all applicable local,
national, and international codes. Failure to observe this precaution could result
in damage to, or destruction of, the equipment.
What the Kit Contains
ATT EN TI ON : The drive contains ESD- (Electrostatic-Discharge) sensitive parts
and assemblies. Static control precautions are required when installing, testing,
servicing or repairing the drive. Component damage may result if ESD control
procedures are not followed. If you are not familiar with static control
procedures, refer to Allen Bradley publication 8000-4.5.2, “Guarding Against
Electrostatic Damage” or any other applicable ESD protection handbook.

Precheck
IMPORTANT
Drives built prior to May 2008 had older style SPDs mounted on the filter
capacitor bank assemblies. If a surge trap style SPD is not installed in the drive, it
is necessary to order and install a surge trap upgrade kit, Catalog Number 21T385253-A01 to insure there is proper transient protection for the equipment.
Inspect the surge trap (SPD) in the drive and note whether the visual
inspection tab has been activated. This indicates internal damage and the need
for replacement. For the location of the surge trap, see Figure 7 on page 11

What You Need To Do
Step 1: Disconnect and Lock
Out Input Power at
the Branch Circuit
To install the filter capacitor assembly replacement kit you need to:
Step 1: Disconnect and lock out input power at the branch circuit.
Step 2: Turn off the drive enclosure circuit breaker.
Step 3: Verify that DC bus capacitors are discharged.
Step 4: Prepare for the replacement.
Step 5: Remove the existing filter capacitor assembly.
Step 6: Remove existing mounting brakets and install new kit brackets.
Step 7: Install the new filter capacitor assembly.
Step 8: Power up the drive and filter capacitor assembly replacement.
Disconnect input power upstream of the drive assembly enclosure. Follow
required safety procedures to turn off and lock out input power during the repair.
