We have 100kva MGE galaxy 5500 UPS but due to some mishandling during start up by a technician (most probably he kept the Maintenance Bypass switch close while turning on the UPS from the inverter) the UPS got some problem.There was explosion type noise form the ups.It seems to me that some PCBs got damage inside the ups.The system is out of warranty so we want to do initial inspection to know what is the problem. Can any body provide me the service manual for this UPS. Or any idea which PCB board should i check. Your help will be highly appreciated.
