Problem with Liebert PowerSure ProActive PSA700 UPS System

My ups does not seem to charge at all. When it is connected to a power source i hear the click and the computer can be started. When the power supply gets cut, the computer is switched off immediately. Whenever the ups is switched on by using the power button, it gives of an infinite beeping sound --
1. If it is coonected to a power source the top green LED glows and the second (middle) orange LED keeps on blinking.
2. When power source not connected the topmost green LED does not glow but only the second (middle) orange LED keeps on blinking
3. The infinite beeping is heard in both cases.

Please help

There is peep sound with power on. Top two indicators are on.


This normally happens when the reserve battery in the UPS has run out of power and needs to be replaced.

I have a Liebert PSA470-120 on one of my computer controlled casting machines. Last night the battery exploded, blew out one of the side walls. Can I just replace the battery or is the voltage regulator...


Personally I would not just get a battery and go for it after an explosion that blew out a wall makes sense to me for you to contact the manufacturer and as some questions and purchase another battery system that is more stable. That would be my worry something blowing out my walls is critical and needs to be addressed what do you think? Thanks for using FixYa! John

The unit is not functioning. There is mains light indicator but the unit does not respond to operation


The mains indicator is just indicating that your UPS is plugged in to the power source.Try pushing the circuit breaker located at the back of the unit some are located in the front panel and some brands call it "reset"button.If this does not do the job,either have it serviced if under warranty by the manufacturer.Doing the work yourself kinda like disassembling a small engine(meaning-it is hard and also breaks the tab for the warranty).If you open it check for broken fuses(hi-amps fuses),and it is possible you'll change some relays and semiconductors.

Hi There.... I have had 2 powersures for awile - and decided to power them up..... Neither would come on. Do the batteries need to be charged, or replaced to make them work??? Thanks, J. Jeffrey


The answer is most likely yes. I am not familiar with this brand but having worked extensively with APC and Tripplite, I can say that when the batteries on these models are drained, they will not turn on until charged. Most of the time you will end up replacing the batteries as they do not do well at charging once they have been drained below a certain level. I would try charging first. If you can get them to full or nearly full charge, you can test that the rest of the electronics in the UPS is working.

My Liebert PSA itON 600 UPS keeps beeping when i turned it on


To figure out what's wrong with the UPS, first you have to do a few things.

When calculating the rating a UPS can handle, it's voltage x amperage. If it's Watts multiply the number by 1.67 to give the rating of the device.

Add up all the devices (use the power supply rating in the computer) as well as any other device, and add them up.

If this rating was exceeded, then you have overloaded the UPS. If it was too long that you did this, then you wore out the battery.

When a UPS beeps even when not connected, that means the battery is very weak.

If the battery is more than 3 years old, it will need to be changed. If the online tests of the unit were done and the battery doesn't need replacing, then other parts of the UPS need fixing.

Check the battery.

How does it react when you simulate a power lose? Unplugg it from the wall to test it to see if it turns to battery power. If the unit goes to the battery backup normally then check to see if it has a reset button on the unit. Please let me know what size unit it is.

the battery is bad, you will need to replace the battery or the whole unit. you can find batteries on ebay. just source the model number. also depends on the size of the unit. you may need to just replace it...just a better value to do it that way.

good luck
