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.
