Hi,
I have the 5KVA model with the common DC Bus Fault. Have thoroughly followed this thread. My main board is more complicated. I have changed the capacitors marked in RED near the DC-DC section.
Anyone was able to find a schematic or give some advice. Its a pity not being able to fix this old but good UPS.
