Automatic UPS system wiring circuit diagram for Home or Office (New Design With One Live Wire) Method #2
Sh*t happens anytime… In case, If you want continuous power supply to the system i.e security or important online work etc or in an area where load shedding is must on daily basis, then you need an automatic UPS Wiring connection. If so, come to the point….
As a basic, we know that each load points should be connected through live (Phase) and neutral wire to operate normally. So in the case below, we have already connected Phase & Neutral (from Power house & Distribution board) to each electrical appliance i.e. Fans, Light points etc.
Now, according to the below UPS Connection Diagram, connect an extra wire (phase) to those appliances where we have already connected phase and neutral from (Power house & DB) (i.e., two wire as phase (Live) with same point as shown in the below fig). And no need to connect extra Neutral wire from UPS as it is already installed & connected before. Now the quieten arise here “Why Extra Phase wire ? … Yes.. Read the following operation story of the new circuit & wiring.
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 or live wire) 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 wire which has already 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 stored Electrical energy in the batteries without interruption.
