I am not expert in electrical matters, I've a working ups shifted from old house to new one.
I tried to connect it to my room bulb as shown in attachment ups.jpg. But as the main supply is cut off and before I can turn on the bulb switch, the wall socket led remains red, ups produces a strange sound and the ups output voltages appear as 50V which should be 220 V. I am getting the impression that ups output is going back and becoming its input, how can i adjust the wiring?
If I disconnect ups output wire-A, the output voltages become normal at 220V.
Any clarification is appreciated, thanks.
