Automatic UPS system wiring circuit diagram for Home or Office(New Design With One Live Wire)
As we know, we had already connected Phase & Neutral (from Power house) to Electrical Appliances i.e. Fans, Light points etc… So according the above UPS Connection Diagram…connect an extra wire (phase) to those appliances where we have already connected phase and neutral from (from Power house) (i.e., two wire as phase with same point). So no need to connect Neutral from UPS as it is already connected.
Working and Operation
(1). When Supply is available from power grid
Then Supply will continue through Phase wire (Note that Neutral is already connected) which is given to UPS from main board (it will charge your battery as well)…and then from UPS to Electrical Appliances… So the Second one phase which is connected after UPS installation (i.e. One Live Wire from UPS) would be inactive because power supply is not available from UPS and batteries (Because it is Automatic UPS System).
(2) When Supply is not available from power grid
then Supply will continue through Phase wire (Output UPS) which is Connected from batteries and UPS to Appliances (Note that Neutral is already connected) . So the first one phase which is connected before UPS installation (i.e. Live Wire from Main board to UPS) would be inactive because power supply is not available from power house. In this case, you consume the store Electrical energy in the batteries.
