Inverter electrolytic capacitor (C5,C6:For CLC6101i 50/65 HE/ CLC6001i 25/35 E models;C8,C9:For CLC8101i 65
HE/ CLC8001i 25 /35 models) check method
Turn off the power, let the inverter electrolytic capacitor (C5,C6:For CLC6101i 50/65 HE/ CLC6001i 25/35 E models;C8,C9:For CLC8101i 65 HE/ CL-
C8001i 25 /35 models) discharge completely, and remove the capacitor from the control printed circuit board (PWB). First, check the case for cracks,
deformation and other damages. Then, using a needle-type tester, check continuity.
Determination of normal condition
The tester needle should move on the scale and slowly returns to the original position. The tester needle should move
in the same way when polarities are reversed. (When measurement is taken with the polarities reversed, the tester
needle exceeds the scale range. Therefore, let the capacitor discharge before measurement.)
4.IPM check method
Turn off the power, let the large capacity electrolytic capacitor (C5,C6:For CLC6101i 50/65 HE/ CLC6001i 25/35 E models;C8,C9:For CLC8101i 65 HE/
CLC8001i 25 /35 models) discharge completely, and dismount the IPM. Then, using a tester, check leak current between C and E.
When using a digital tester, the (+) and (-) tester lead wires in the table must be reversed.
Values in ( ) are for digital tester.
