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. not so impressive

  2. Is neutral connected to the main neutral? as per diagram

  3. Hi,<br /><br />UPS input and output neutral is shot circuited? Is this ok<br />If UPS for one room and generator for other room is connected … Still can we connect UPS outout neutral wire to mains ?<br /><br />thanks

  4. For 5 fans and 5 lamps( energy saver) 1000 watts UPS with 2 batteries of 180 Amp/Hr is good, its have better efeicency. ok

  5. how to change the frequency of a ups? i heard that there is a knob in it for the purpose<br />

  6. Thanks i do very easily.

  7. This is my very first time I have visited this website. I found lots of interesting stuff in your blog.<br /><a href="http://www.adeptpower.co.uk&quot; rel="nofollow">Generator Maintenance</a>

  8. Seems to me like there isn&#39;t enough protection from the main switch to the UPS in case of a short circuit in this area.

  9. thanks sir i found lot of info from this for my project work for my school level

  10. I disagree with the first comment. I think it is valuable and informative post..

  11. You described many interesting elements in your post. Thank you very much for such informative blog.<br />https://plus.google.com/104896718356367167029/about

  12. I dont think it&#39;s save

  13. I want to connect only one points example. Only c.f.l but where more points.how to do? Conection

  14. sir i need to contact u for a similar kind of project, plz tell how to contact u , regards <br />haider

  15. Diff. Between the first diag. &amp; 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.

  16. I can&#39;t understand the second diagram<br />

  17. Hello Wasim Khan..first of all a very big thanks to you…<br /><br />Your description with the diagram is just very very simple to understand…<br /><br />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.<br /><br />My queries are simple. They are:

  18. I have read all your automatic ups wiring post.<br /><br />I am clearing my doubts again…this time not in complicated way.. :)<br /><br />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).

  19. Most Welcome Dear… and Take Care,,, Best wishes,,:)

  20. 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&#39;s a bit of a contradiction from the previous diagram!

  21. Yes… You have to connect the Neutral Wire from UPS (Output) to the main neutral link.<br />

  22. My question, is really on why is important to connect the neutral wire from UPS (Output) to main neutral link? Wouldn&#39;t it short-circuit?<br />

  23. 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?

    • 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… :)

  24. 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

  25. 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).<br /><br />

  26. 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.<br /><br />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

    • Sudipto Sinha.. Sorry and again sorry from the core of my heart for too late reply and response…!!!<br /><br /> Now… I read all your comments and Queries… your setting and system is good and proper… ( two 12 V batteries (in Series) for 24V system) .. <br /><br />Just Conect the Neutral wire (Output of UPS) to the main Neutral Link/Wire in your Distribution Board….

    • thank you very much Wasim Sir. I have just read your reply and I&#39;ll connect the UPS Output Neutral to the main supply neutral wire coming from Main switch. <br /><br />I am doing the wiring today. :) I&#39;ll definitely reply you if all works fine. I know it will work as you described here.<br /><br />Once again thanks for your reply.

    • Thank you so much for appreciation…. If you face any problem, then please reply… it would be great for us if we help you…

  27. hello Wasim Sir, after two days of wiring my house, I have completed the whole house wiring today. And its working!!!! Thanks a lot Sir. Everything is working perfect as it should. :)<br /><br />Oh, I just did one thing what I want to tell you. That is, I connected a 10Amp MCB at UPS Output phase line instead of Fuse what you described here, as MCB is more reliable than fuse and I can easily

    • Dear Sudipto Sinha, <br />I really appreciate your successful (Practical) work and It restored my energy ;)<br />I am sure that your these kind of steps are Guarantor of your bright future in Electrical Engineering… Go On and best wishes,,,, <br />If you face any problem in future (God forbid)..Then we are here (Hod willing) to help you :)

  28. What is a neutral link? As per my understanding, it comprises of mainly neutral wires for each subcircuit and the main neutral wire if I am right? Please correct me if I&#39;m wrong. <br />Sir in the neutral link, there are many sub-circuit wires. I know we have to connect to the main neutral wire. So are you trying to say from the UPS Output the neutral from it should also be jodoed/twisted/

    • Dear Azaan Kaul… you are absolutely right about the Neutral Link… Neutral Link is an electrical connectivity device which connects main Neutral wire to various other room neutral wires so that the Main Neutral Connection goes to other sub-circuit or other rooms neutral connections.<br /><br />As the above circuit diagram describes that you have to connect the UPS Output Neutral to the main
