Somewhere in this forum i read that the ups should be connected to the main supply at all times and i did just that, but when the power button is off along with the no battery charging the top of the ups seems to be getting hot for no reasons and the fans are still off as they only run when the ups is running providing power thro battery. can anyone tell me if this is normal? Should i rma it? I just got it 2 days ago

One thing I originally wondered about was your post regarding the battery: " the lower part where i presume the battery is located is very cool".

The tower units I have worked with all came with a battery that was not connected and had to be "installed" in some manner.

Primarily to prevent some current flows leading to overheating during storage and shipping. End result being a fire.

But I must concede that there are different rules and requirements for other countries. No disrespect intended.

The link and User Manual indicate the presence of a resettable thermal circuit breaker.

Page 4, Feature 4.

If your UPS does not have the circuit breaker then you may have a counterfeit or mislabeled product.

Plus, if you did not install...
That does not seem normal at all.

Which model Back-UPS?

It the UPS directly connected to a wall outlet or connected via some extension cable or power bar?
(Extension cables and power bars are not recommended.)

Any LEDs? Any beeps?

Are you using the monitoring PowerChute software? The software may provide some insight as to what could be happening.

In any case, doublecheck the battery installation and connections.

Does the UPS remain cool if it is not plugged in and the power switch is off?

If the UPS is cool, there may be a problem with the power outlet serving the UPS.

If hot while unplugged and switched off the UPS/battery may have a problem.

No leds, no fans, no beeps, the lower part where i presume the battery is located is very cool, The part which is hot is the upper behind of the ups just next to the fans where i presume the transformer is located is hot enough to feel it clearly but not hot enough to prevent me from touching it, if i turn off the power the fans run for a few seconds and then turn off, but the ups doesnt heat up anymore. About powerchute it doesnt support it

Plus, if you did not install the battery yourself or know who did then that is all the more reason to be suspicious about the history of that UPS.

At this time all I can suggest is that you carefully read through the User Manual.

Two reasons:

1) To verify that the UPS is correctly setup and configured (including battery).

2) To work through the Troubleshooting section to eliminate possible issues.

Check every indicator LED to verify what is working and what may not be working. Post accordingly.

Could well be that I have missed or otherwise overlooked something.

Perhaps someone else following this thread will be able to offer further suggestions and comments.

I have no problem with that.
