A tough one Tepin. Very hard to diagnose via this medium since the Pwr Cndtr is a Ferro-Resonant device you really need to have the unit in front of you with appropriate test instruments. Im not sure what sort of protection devices (if any) may be installed to prevent untoward currents flowing in the capacitor(s) in certain situations but if there is (HRC Fuses for example) then replacement of these may fix the problem.
I would suggest though that the best bet would be to contact Powerware Australia and ask them for their advice. Ive always found them to be more than helpful when assisting customers with problems on their UPSs, etc. The contact number Ive got on file is 1800 034 401..... hopefully someone there may be able to help you out over the phone if it is something simple. All the best,
