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. what is the size of wire shoule be used in connecting fuse box to ups

  2. Dear Wasim Khan<br />I am thankful to you for the UPS diagram on your blog. I have found it perfect for installation of my new UPS with the system.

  3. Thx…. Much Appreciated<br />

  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

    • Suman@<br />There are more UPS wiring diagrams under the &quot; Electrical Wiring &quot; Tab. ( You should Check)<br />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.<br />If you want to connect neutral wire, then Use this method.<br />

  5. Thanks

  6. How about pc

  7. What type of UPS it is in term of on-line or off-line UPS?

  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..? <br /><br />UPS will trip..? IF yes, After Electric board power comes, IT will not switch on right.? Then my house will not get power..?<br /><br />Please explain me.

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

  10. I have luminus sinwave invertor, i transfered to a new place , one elctrician came and connected it and it and not working , can u guide how i connect its out put and input in my mainswitch of my house.. shall bgr8ful<br />

  11. sir i wan to ask that as i successfully installed ups as in your diagram. but can now iwant to use generator can we use same appliance wired for UPs on GENERATOR means live wire plug into generator is it works<br />

  12. 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

  13. do you have single phase amf diagram , can you post it? someday i want to try install it at my house. thanks

  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.<br />

  15. i have a problem with the output socket of my inverter, it gives output through left Pin in the socket when connected to mains and then supply changes to right pin when mains off or runs with battery

    • I resolved my problem by Interchanging the input phase and neutral. Now the output is only from right pin

  16. sir, when i switch off main breaker , my home neutral line getting power. why? we have installed inverter circuit same as above. <br /><br />note:all equipments working as usual for years with same inverter diagram. today simply checked neutral line, and got this problem.

  17. Harish:-sir as per u r diagram the load is more as fans,lights ,chichen ites and ac&#39;s etc…are connected together on only one line…if the incoming power is switched off or shut down the load will drawn the all power charged in battery with in a seconds……so that we hav to drawn another one line for load…..

  18. Thanks for such information sharing with us ….<br />i am still confuse with this diagram…<br /><br /><a href="http://www.adeptpower.co.uk&quot; rel="nofollow"> ups system</a>

  19. Respected sir,<br />i have complete UPS system in my house, UPS also charges the battery now i want to connect solar panels to charge the battery. one i/p from battery and other i/p from solar panels, Confused what should i do?<br /><br />Zubair Anwar

  20. What I would really like to know is who will be the <br />notes written to <a href="http://bluepromoyo.blogspot.com/&quot; rel="nofollow">bluehost coupon code 2013</a> but <br />these forms of loans are normally only accessible to highly <br />experienced and successful developers taking care of projects over <br />$5,000,000.

  21. i wanna ask that if the plug attatched to ups is plugged out of ups and put in the socket in main circuit where the charging plug was attatched after removing it??

  22. Thank you very much for the simple connection diagram.<br /><br />But I have doubt. I think UPS is not connected to the Earth wire in this &#39;New Design With One Live Wire&#39;.<br /><br />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?<br /><br />Please reply as I am looking forward to instal a home UPS in the

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

  24. Connect WAPDA Phase and Neutral wire in UPS inlet (Input)

  25. This comment has been removed by the author.

  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

    • Dear Azaan Kaul@<br /><br />As you know, in your case, we had already connected Phase &amp; 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

    • Thanks a lot Wasim Sir! Can you also provide a tutorial on how to install tube lights, exhaust fans etc.? Try to put some stuff related to Air conditioning too! Anyways really good website! Simplifies things!

    • Dear Azaan Kaul<br /><br />We Will try our best,,Stay tune here….<br />And bundle of thanks for appreciation…

  27. how can change automatically when power faliure

  28. Nice info thanks for sharing<br />

  29. 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

  30. this is for ups but what about only 3 pin invetrer which contain 3 wire in a single cooted plastic cover which are responsible for input or output<br />

  31. Great web site you have got here.. It&#39;s difficult to find <br />excellent writing like yours nowadays. I seriously appreciate people <br />like you! Take care!!<br /><br />Feel free to surf to my weblog <a href="http://www.charlieshandles.com/&quot; rel="nofollow">poignées de portes</a>

  32. I hope you may continue to keep in posting new posts thank you for sharing your great experience among us. distribution boards

  33. can i use this diagram to power up an a/c small 200-400 watts refrigerator and a desktop computer?? your answer regarding this is much appreciated. thank you.

  34. can i use this circuit diagram to run a small a/c 200-400 watts refrigerator and a desktop computer? I have 850va pure sine wave inverter.

  35. Sir i want to connect 2kv stablizer and600VA inverter in my room.how it connect?

  36. In my inverter I am getting phase in output in one pin when current is available and it is getting changed to other pin when there is no power…i am confused now which one to use for single wire.. if i interchange the single wire pin my appliances are only working either in power on mode or in power off mode, please help me to correct this prob

    • I am facing the exact same problem since yesterday after the inverter was taken off and reconnected again. Can someone help? One of the earlier comments suggested to swap the input phase with neutral. I tried that but it didn’t help – the inverter doesn’t recognize the input if done that way. Am I doing something wrong?

  37. Dear author….u said while supply available from grid the pwr comes from main to ups to charge battery….then after ups to appliances.. what u said at starting is 2nd phase wire i.e from ups is inactive if it is inactive how pwr reaches from main to appliances…i asked because there os no direct phase connection from main to appliances

  38. can we take out put from phase terminal only for house wiring.

  39. hello sir,
    you have a marvellous site here. I’ve learnt quite a bit, almost enough to attempt a diy installation of an inverter! I have planned for a 1500va system with 2 batteries. here comes the daft question. I’d like to make it whole house. I’ve no major power hungry equipment. lots of 10 watt LEDs, two laptops, a small set top box with LED TV. I do however plan to get a. induction stove at some point,though there will not be a need to run it off an inverter. almost forgot my question. could I just connect the ups to the fuse panel directly and call it a day, or am I being silly?
    thanks in advance!

  40. Hi my question is when wiring the light switch/point with the UPS and mains wire, in which terminal of the switch do I have to put the UPS wire, is it in the input MAINS PHASE terminal of the switch from where you get the MAINS or the output phase terminal of the switch which is connected directly with the load. Could you please show a diagram if you can?

    In simple words in the pin of the switch in which you put the MAINS phase, do I have to put the UPS wire on that very same MAINS phase pin of the switch, or do I connect the UPS wire to the Output of the Switch, which is directly connected to the load such as fan, light etc.

    Please show a diagram if you can:

    http://img.bhs4.com/3a/2/3a2455de36bb27d562fc6a6e2eb037294131ac34_large.jpg

    Can you make something like this as a diagram in detail please?
