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
. 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

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.
