Automatic UPS system wiring circuit diagram (New Design Very simple) for Home or Office

This is an Automatic UPS system wiring circuit diagram (New Design Very simple) for Home or Office.. Which I have tried successfully in my friend Home...
 This Automatic UPS wiring diagram number 1..... After that you may also read this diagram number 2 her...i think it will be more simple.
 Automatic UPS system wiring circuit diagram for Home or Office (New Design With One Live Wire)
                                                  click image to enlarge

Purpose:
This wiring circuit diagram is design for when you want to give supply to particular rooms in the home or office in the building in case of failing the power supply.  And you want to supply power continuously to the laptop, computer etc in that specific rooms or office in case of low wattage UPS or single battery or in case of when generator system is not available. .
Now take a review of this circuit diagram.
   How to do this wiring in Home or Office.
First of all, remove those Live (Phase) wires from the main distribution board (from the circuit breaker) of those particular Rooms (As shown in Fig) which you want to give automatic supply (in both cases from Battery and Power House without any interrupt or disturbance). Suppose I want to connect only these two rooms with this system as shown in fig. Then connect these two live (phase) wires at the end as shown in fig. Now do the same wiring (Connect UPS, Battery, Home appliances etc) as shown in fig. Done
    Working Principle: 
1.    In case of, when Power supply is not available from power house


Then power flow will continue to those particular rooms or office at this way from Battery
                                        The Blue Line show the power flow.
                                                              click image to enlarge 
 2.    In case of, Power Supply available from power House.


Then power flow will continue to those particular rooms or office at this way from Power supply (Not from Battery, because when power supply available, then battery will start to charge through UPS.      
                          The Blue Line show the power flow.

    1. ♦ its not short circuited..., when Phase touch neutral without load then Short circuit occurs.
      ♦ refer to the other diagrams for this purpose under the " Electrical Wiring",→UPS Wiring diagrams.

    Seems to me like there isn't enough protection from the main switch to the UPS in case of a short circuit in this area.

  16. Diff. Between the first diag. & the second is that in the first you just added neutral to the o/p of the inverter which was not necessary as already exist to the points to complete the ckt.

  17. I can't understand the second diagram

  18. Hello Wasim Khan..first of all a very big thanks to you...

    Your description with the diagram is just very very simple to understand...

    But I have a few queries which I want to ask you. If you describe and simplify my these queries then I am going to install an inverter in my home as installing an inverter is very urgent in my room.

    My queries are simple. They are:
    1. I want to do wiring connection for inverter in 4 different rooms in my house. And there are existing wiring connections in all rooms for direct power supply (240v AC line coming from power house). So I want to connect only some of my required electrical equipments to the inverter not all the equipments in my house. So should I just connect those equipments to the inverter output as per your diagram?

    2. And 2nd one is: if I connect my desired electrical equipments (not all equipments of my house) to the inverter as per the diagram then when there is main supply from Power house is available, will those inverter connected equipments work over the direct main line instead of inverter battery backup? I mean is there any short circuit would occur or the inverter just cut the battery line and those inverter connected equipments can work over 240v AC direct line coming from power house?

    Please take your time to understand my scenario and please clear my above two doubts.

    Thanks in advance and looking for your reply.

    2. Hello Wasim Sir,

      Thanks for your Concern and reply.

      Yes I checked that post too in here http://www.electricaltechnology.org/2012/11/automatic-ups-system-wiring-circuit_23.html...

      Thats why I was little bit confused. As you suggested on that post to connect an extra phase wire with all those equipments to inverter output phase point only and no need to connect extra neutral wire to inverter as the existing main power supply neutral wire is already connected to those equipments. That diagram and your explanation I understood very clearly but after seeing this Post and Diagrams in here I got confused. Sorry.. :(

      What I am thinking after seeing both posts, what connection should I follow in my case? This one or the previous one where you suggested to connect only an extra phase wire to my required equipments only (not all equipments of my house) to inverter output phase point?

      I want auto-cut system like when main power supply is available, all equipments would work over main power supply but as soon as power goes off, the inverter connected equipments would automatically start working over battery backup is their respective one way switch is on or I put on the switch of inverter connected equipments.

      Please guide me sir...

    3. Please give me the right solution sir..

      I am waiting to hear from you. Please give me the right solution so that I can install an Inverter for my room. Its urgent.

      Thanks.

    4. Dear... in your case, you may use the following diagram..i.e you may connect another wire as Live wire...
      here is the diagram
      http://www.electricaltechnology.org/2012/11/automatic-ups-system-wiring-diagram-in.html..

      also, if you cant manage that diagram (As mentioned in the above link) then you should follow the same diagram as shown in the above post.
      in this diagram, you will have to remove all those( only live) wires of specific appliances i.e fans light etc... form Circuit breaker which you want to connect to UPS... don't worry...it will work on both i.e main supply and UPS automatically..
      and then connect (all disconnected live wires form CBs) to the UPS output (as shown in the above image)... you have done...

      Delete

    5. eDon't worry...I am using the same wiring diagram, that why i suggested to you...
      The working of these diagrams ar:
      When main supply available... your all appliances will work on Main Supply..as will as, it will charge your battery..
      When main supply not available... Only those appliances will work which you have been connected to Inverter (UPS)...
      Thanks

  19. I have read all your automatic ups wiring post.

    I am clearing my doubts again...this time not in complicated way.. :)

    I want to connect some of my electrical equipments of my house with Inverter. When main power house supply is available then all electrical equipments as well as those inverter connected equipments should also work over main power supply (not from battery). But as soon as main power supply goes off, then inverter connected equipments would continue working over battery backup and rest of the other equipments which I don't want to connect to inverter, they will go off. And then when main power comes back, then all equipments(connected to inverter plus non connected to inverter) would work on main power supply only.

    This is what I am looking for.

    Please sir, try to understand my question and please suggest me the best diagram or solution as soon as possible so that I can install an inverter for my house.

    I'll be highly grateful to you. :)

    2. Thank you very much Sir... :)

      I'll do what you have told me to do. I think I have figured it out on which way should I follow as per your diagrams. Your posts helped me a lot.

      And I want to say thanks again and I will reply you again as soon as I successfully complete the wiring and installation of the inverter.

      Take care.

  21. Dear Sir, do we have to connect Neutral from the output plug of the UPS? Because you said in your previous diagrams that there is no need to connect a neutral wire since it is assumed to be already connected to the mains electricity? Thanks. It's a bit of a contradiction from the previous diagram!

    ReplyDelete
  22. Yes... You have to connect the Neutral Wire from UPS (Output) to the main neutral link.

    ReplyDelete
  23. My question, is really on why is important to connect the neutral wire from UPS (Output) to main neutral link? Wouldn't it short-circuit?

    ReplyDelete
  24. Plus one more question from the phase output of the UPS instead of fuse can we use an MCB aka circuit breaker to help keep the circuit safe? Because the problem of the fuse is that if it breaks finding a replacement is hard so can we use an MCB switch instead of the fuse?

    ReplyDelete

    1. Yes Wasim sir, I have the same query too like Azaan Kaul that can I connect a MCB instead of a fuse at UPS phase output? and if so then what would be the MCB Ampere? should I connect 10 Amp MCB? Please sir, reply this too... :)

  25. Hello Wasim Sir, this is Sudipto once again.. Today, I have bought Luminous Ion Sine Wave Inverter 1500 VA as per my required Load. Now, I have a query... On the back panel of the UPS, it is printed 24V DC. Thats where my confusion comes in my mind. Earlier, I decided to buy 12V 200Ah Exide Tall Tubular IT750 battery. But, that is 12V battery and now when today I bought the UPS, I saw there is 24V DC Printed on the back panel of the UPS.

    So, my query is if I buy one 200Ah 12V Exide battery and install it then the UPS will work or not? or should I buy 24V battery. Please sir, clear this confusion. I didn't buy the battery yet and tomorrow or sunday I am going to buy the battery.

    Please sir check this for me.

    ReplyDelete
  26. Wasim sir, I have figure it out what I asked yesterday at night, that the UPS System works on 24V DC Supply when main line goes off. So, I think I have to connect two 12V Batteries in series and hence the battery bank should be connected to UPS so that the Voltage will be 24V but Ah of the battery bank will remain same. So, I decided to buy Two Exide IT400 Batteries (12V, 115Ah both).

    Now I have only one question.That is, the specification of the UPS says the battery type range is 120Ah-150Ah. So If I buy IT400 which has Ah rating 115Ah, then the UPS will work or not? as 115Ah is lower than the UPS specification 120Ah minimum requirements.

    Please sir clear this question earlier so that I can buy the right batteries.

  27. Wasim Sir, I have finally bought two Exide IT500 (150Ah). All materials are ready to install. I am going to do the wiring process tomorrow. But I have one confusion before doing wiring. Please reply it urgently sir. Its my painful request to you.

    My confusion is should I connect the UPS output neutral to main supply neutral wires directly? In the diagram, I can see that you have mentioned a "Link" device which is present on Neutral wire coming from main switch and you have shown that UPS Output neutral is to be connected after that "Link". What is this "Link"? Is this important or should I just connect the UPS output neutral directly to the main supply neutral wire?

    Please sir, answer this question. Its my painful request to you. Its very very urgent to me.
