Automatic UPS system wiring circuit diagram for Home or Office (New Design With One Live Wire)

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.

    1. It depends on your load requirements....in other words, your number of final sub circuits.

  4. So as per your diagram we connect only the live wire from the ups output to the loads we want to connect. There is no need to connect the neutral from ups output to the load circuits. My ups was connected like this earlier. But now I have shifted and when i reconnected at new place as before and switch off the main switch to check the attached load doesnot work. I was wondering from where the loads will get the neutral as the main switch cuts off both the live wire as well as neutral wire. Please advise as the maintenance guy from ups company comes during day and i am out most of the time during the day. Do i need to connect neural as well from the ups output to the main switch to power the connected load under ups backup plan. Thanks

      There are more UPS wiring diagrams under the " Electrical Wiring " Tab. ( You should Check)
      in this case of above diagram, we have connected only live or Phase wire from UPS to the load, because Neutral wire already connected to the load ( from Distribution board) so no need to connect Neutral wire.
      If you want to connect neutral wire, then Use this method.

  8. Thanks for the Circuit. I Think, I can install my new UPS alone. But I have one doubt. If my House load is more than the capacity of the UPS means..?

    UPS will trip..? IF yes, After Electric board power comes, IT will not switch on right.? Then my house will not get power..?

    Please explain me.

  9. Dear Parthib@
    As we know that Inverter should be greater 25% than the total Load
    Suppose your Load = 800 Watts, than,
    800 x (25/100) = 200
    800+200 = 1000 Watts
    This is the Rating of the UPS (Inverter)
    So, before installation , Try to calculate the rating of UPS according the load.
    Secondly@ Can you operate a 500W Motor on 110 W???? So that is the answer.

    1. Thanks for the info,

      At present.

      I have 600VA mahindra Powerol Inverter and 150AH Amaron Battery.

      My full Home load is 4 light and 2 fans and 1 TV.

      So can i connect this type of wiring.?

      Delete
    2. Dear Parthib@ what is the rating of lights and Fan???
      suppose, if we assume 40watts fr each then 40 x 4 W + 2 x 90 W (for fan) + 300W for TV = 560 W.
      So you can use it but the backup time of battery would be low.

    Hello sir, i have an pure sine wave 850va inverter and i m using your circuit in which one live wire is connected from inverter/ups output.. my half home appliances runs from directly grid power and half are through inverter and i use the common nutral wire.. now my question is if i switch off the input it will go in backup mode but will it affect my inverter because we use only phase/live from invereter/ups and the nutral is common nutral... half of my home uses grid power(same nutral) and half on invereter so in any case if i switch the input off inverter will go in backup mode now as we use same nutral is it possible to fed grid current in inverters output socket through phase/live?

    Also if thunderstorm lightning come can i just switch the input off and take out the inverter input plug for safety? other things will run from inverter battery backup.

      i think u can't understand what i m trying to say(i dont know much about these things so i think i m unable to express)... i did same thing just like one of your diagram http://www.electricaltechnology.org/2012/11/automatic-ups-system-wiring-diagram-in.html now i m trying to say is if i just switch off the inverter input then the stuffs(which are connected to inverter) will run from backup right? now is there any possibilities of damaging the inverter because other things(wihch are not connected from inverter) will run from utility power and the ones which are connected to inverter will run from inverter Backup and both will use the same nutral... also if thunderstrom lightning strikes can i just switch off and pull out the input plug of inverter? so that lightning will not damage the inverter?

    5. (1). No. This circuit is designed for that specific operation.. So no need to worry. it will work and it will never damage your inverter.

      (2). Yes! you should do (for safety purpose)

    6. Kudos to khansaheb for such beautiful & simple diagram with explanations. Before I read your article, I was very afraid & did'nt understand the wiring. But now it is very clear cut. But you didn't showed earthing wire to the inverter input and other appliances which is very critical,if anything goes wrong. God bless you.

  14. UPS’s are not expensive compared to the rest of a VoIP system, but unless they are budgeted for during the planning process they tend to be overlooked. When the UPS planning is done for the access closets, it is also important to make sure there is enough electrical power to the closets.

    Thank you very much for the simple connection diagram.

    But I have doubt. I think UPS is not connected to the Earth wire in this 'New Design With One Live Wire'.

    Is there any way the UPS could be earthed? Does the absence of earthing affect the safety/life of the UPS? Is this important at all?

    Please reply as I am looking forward to instal a home UPS in the near future.

    1. As you can see that Neutral wire is already connected to all appliances...so no need to connect another Neutral wire...
      another thing .... That Neutral wire is not for safety purpose..just for completion the circuit..
      Also you can connect Earth (grounding) wire only with UPS for safety purpose...

  26. Sir one more question, your diagram does not specify what to do with the main phase wire for e.g. if I connect a fan switch to the UPS, the UPS wire is connected to the switch, but what do I do with the existing WAPDA Phase wire that was connected to the fan switch before wiring the fan switch to the UPS? Do I jodo/twist the UPS and WAPDHA Phase together into that fan switch which I mentioned in the example?

    1. Dear Azaan Kaul@

      As you know, in your case, we had already connected Phase & Neutral (from WAPDA) 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 (wapda) (two wire as phase with same point). So no need to connect Neutral from UPS as it is already connected.

      Now check the operation...
      (1) When Supply is available from power grid (in your case, WAPDA)
      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 (in your case, WAPDA)
      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 (Wapda). In this case, you consume the store Electrical energy in the batteries.

      Also wait for a while...I will update this wiring diagram and put some description..

    sir, diagram is ok. we have 3 phase connection. living hall on phase 1 and bed room on phase 2 and kitchen on 3 phase. if i connect my invertor on one single line from invertor to tubes and fans it will work. when all 3 phase current (grid) fails no problem. my invertor was connected to phase 1` for charging. during night phase 2 (bedroom) power supply from grid fails, how my invertor will supply to bed room, since, phase 1 power supply is there ,so auto change does not work or it will work even one phase supply from grid , fails also ?

    2. doubt. when i give connection to one tube throught one live line system, when power(grid) fails, invertor will supply power to my switch board, and switch is on tube or fan works automatically.o.k. is this power supply will go back to main and there from main gird supply wires also.since, there is no power in main lines my battery power will travel to electrical poll?
