Hello Friends,

At my home due to main board placement & position, I use Extension board to power up my System, i.e. plug SPIKE to extension board & than all connections from SPIKE i.e 17" CRT Monitor, CPU & Router. This arrangement is there from last 3 years & no problem so far.

Now I bought UPS (didn't think before buying how to power up UPS :ashamed:), so is it advisable if I plug ups in Extension Board & than connect Monitor & CPU to UPS?

I plan to power up system as follows:

Main Board >>>> Extension >>>> UPS >>>> Monitor & CPU
PS: Router has power adapter with long cable so can plug it to extension.

Waiting for replies,

Thanks :)
 
sorry I also have almost similar dilema..I recently got APC Back-UPS RS 1100VA..Now it has total 6 plug out which only 3 has ups back up and 3 for charge protection..I allready added monitor,cpu and modem to the 3 back plugs. Now I want to add two more devices for backup - speaker and router .Can I connect an extension board to the UPS to add up more devices

here is my plan >

mainboard>ups>extension board>monitor,speaker,router,cpu/

please suggest
 
^^

Yes you can. See nothing wrong with it. Just that you will LOAD the UPS quicker during power outage. Should be fine. Keep the contacts firm and tight, so there is no sparking.

thanks,,I will connect my cpu and monitor directly to ups and remaining one plug point will use for extension board to power my speaker and wireless router..can you suggest some good branded extension board, as I know belkin has some good quality extension/spike board -which are also pretty costly//

my apc ups 1100 va =~ 660 watts as per their site I hope it can easily hold up the load for my current devices
 
Hello asingh,

What will be your suggestion about my query, shall I implement with my plan i.e.

(1) Main Board >> Extension Board >> UPS >> Monitor & CPU (most easy & handy for me)

OR

(2) Main Board >> UPS >> Extension Board >> Monitor & CPU (need some adjustment)

If you are connecting UPS to an extension board , it is advisable to have a good quality extension like belkin's.
 
As I read in the APC manual - they suggest to connect the UPS power cable to direct mainboad power but not to an extension board.
 
Both are fine, as I can see.

1. socket --> UPS -- > extension --> system

2. socket --> extension -- > UPS --> system

Just make sure the extension is certified to handle equivalent or greater Power load then which you will require.

now why on earth would you want to plug your speakers on the UPS? That is just asking for the UPS to die down 10 times faster.

I did a make-do extension board, I took a normal extension board and cut the three pin plug and put the PSU plug (?) on it. Worked like a charm, costed me 50 bucks for the whole shazzam and now I run my Skype Phone, Wireless Router and ADSL Modem off it.

The answer to your question depends upon two things.

1. When you say extension board, are you talking about one with surge supression? Does it have a ground pin?

2. Does the UPS have surge protection?

It is not advisable to connect two surge protection devices in the same circuit.

Read the following to know why.

[oclug] UPS and Surge Protector

That is why UPS manufacturers say that the UPS (with surge protection) should be directly connected to mains and surge suppressors should not be connected to UPS output. Especially if its not a pure sine wave UPS.

If the extension board has no surge protection, and is just an extension board. Then

you can connect your UPS to it or the other way round.

If both have surge protection, then don't connect either way. Buy an extension board without surge suppression (or get one custom made).

Above is the reason for that recommendation.

Hello viki & asingh,

UPS is APC 550 & extension-board is just simple to make power available where main board is out of reach or requires more socket for 2-3 equipment to connect.

Extension board with me has 3 pin socket & power-cable with 3 pin to get power from Main Board. It doesn't have surge protection etc.

I also have MX-series spike guard.

Do you mean that one should not connect Spike Gurad to UPS? but normal/simple power-extension is OK?

APC manual says that same model have auto surge-protection.

Thanks for help friends. :)

Using same extension I ran my system from last 3 years without any problem, so does it means extension is OK to Power-up APC 550 UPS.

Thanks for replies.

If u are sure that the extension board has no surge protection then you can connect ups to it, or vice-versa. Also make sure u have proper ground and the ground pins of the extension board are connected to the ground pin of the wall socket. Sometimes ground pins in extension boxes are not wired.

Wall socket has 100% ground, confirm, but how to check Extension board for ground without opening it? :ashamed:

Safe methods of testing.

--------------------------

1. Make sure the extension box is unplugged from the mains and not powered when you do this test. If you have a multi-meter with continuity test, you can test the continuity between ground ping of the extension board plug and the ground pin of each socket of the extension board.

2. You can open the extension board and check if ground pins are wired. Do this only if you are comfortable with opening and reassembling the board. Also, make sure the extension board is unplugged from the mains and not powered when you do this.

Risky Methods (Do it at your own risk)

-------------------------------------------------

Or you can try any of the ground tests that are usually done at the wall socket, at the extension board sockets. You should be extra careful when you are doing these tests as electricity(high voltage) is involved.

The reason for that is, the extension board may not be able to the required current.

For example, if you go for cheap branded extensions, it would support maximum of just 4 amps... which infers 4*220 volts = 880 watts(Max) its because of the cheap wires used in the extension cord.

There is no difference between a Mainboard and a extension board as long as the wires used are of good quality. For that fact if the main board has a cheap wire connected from your Home Mains... even that will not be able to supply the required amps for the UPS
 
@kishore.chander: thanks for insight, I had a custom made extension(wooden) board with 6, 5 pin socket. The wire that used is a thick black colored wire. I asked the electricity shop guy to use good quality wires. Is there any way to check whether the wire is good enough ?

Yes, you can easily figure that out with the help of company name on the wire. Go for good branded cables. The cables used for AC's would be a better choice. Those can support upto 15 Amps... which infers 15*220 - 3300 watts.

Ask for the gauge of the wire used. Or you can personally go to a big electrical store ask for the best branded wire...

Always make sure that the extension board that you have is connected to a 16 amps socket I mean the big size plugs in your mains.
 
@kishore.chander: can you suggest some name for the wire brands ?

Unfortunately my mainboard plug is not 16amps..its a generic 5 pin plug :(
