I am a new member to this Forum. I have a 800 VA online UPS working on 12 volt Battery. When the UPS is connected to 230 v AC power suply, a 12v battery is charged and at the same time stabilized 230v AC output is available which can be used to operate computer, music system and lighting etc. When power supply is failed, the built in Inverter will generate 230v / 50Hz AC by using 12v battery and automatically takes the load connected to the UPS instantly. Now I wish to install the UPS to one circuit of home electrical load. Please help me by providing the wiring diagram for the same. Thank you in advance.
