Question about Powerware Computers & Internet
SOURCE: Replaced old 12 V, 33
Mike Decamp is clueless. That is not a answer. The UPS has large DC capacitors. These do go bad over time. The capacitors are required to maintain a good DC Buss and helps in assisting when putting the UPS in bypass and back online. You can not turn on the inverter with out precharging the capacitors. Get the part numbers of the caps and replace. Make sure UPS and batteries are off or you will get shocked.
