Powerware 9125 power problems

Powerware 9125 3000VA UPS will not power up long enough to make it through the self test. I am set up with 2 EBM modules as well as the internal batteries. Have been sitting for nearly two years in a dirty warehouse, although the inside electronics are very very clean and I see no fuses open. Obviously the batteries might be shot, but I have no other components to really test that, however, I would think that the Line AC light would still turn and blink on when I got Utility power. However it doesn't. Hit the power on button and it tries to boot, but turns off and immediately tries to reboot. On the off chance it does work the batteries must be shot because it never reaches battery mode. Just shuts off. Any ideas? Thanks in advance for taking the time!

Most modern ups units will not start at all without the batt, so disconnect the extra packs beg, borrow some new or old good batt blocs same spec as the original internal ones, as this is just a test any set of batts that is just ok will do.

fit them to the ups unit and see if it will start. if it will then you will need to replace all the batt blocs in the whole system.

If it does not start then the ups is faulty.

If you are not happy fitting /working with batteries then get a tech to do this work for you, batteries are very dangerous, they are always live and need to be handled with care at all times.

Hope this helps, thanks for asking FixYa

Hi,

After you replaced the batteries did you perform a manual battery test?

If not do so.

SOURCE: Bypass alarm flashing on a Powerware 9125 UPS

it is possible the bypass alarm is flashing because the i/p and o/p are not within range to switch without a break.

they need to be nearly equal in volts and freq so when the ups switches the ups o/p is continuous.

you should be able to check this with your ups software.

Powerware ups 6kv indicates Bat disconnected


1st does this have external battery modules or is it only the Internal batteries on this unit? You can disconnect the EBM's and the unit doesn't alarm even removing the internals with EBM;s attached won't cause an alarm. But it you only have internal batteries, open the front cover by pressing in the sides on the bottom left and right and pull it out and up at the same time revealing a black cable with a small anderson connector, make sure it is connected. you can pull the batteries out to check them to be sure they are properly seated. By the way the UPS in the picture only went to 3000va so is the 6Kv a different model?

Self test failed


This could mean that you have bad batteries in the UPS. Usually when it does this test its to test the batteries. So the UPS will start a battery test, Rectifier will lower it's voltage to a set point where the UPS tell it self to go on battery. If the UPS detects that, the battery % is lower than the allow set point to perform the the self test it will stop the test immediately. This way your load is not interrupted. Also could be that the intelligent modules or power modules have a issue which again the set point is to low or out of range due to the total of load the ups has on the output compared to the total power modules that might have a problem with. The UPS is smart enough to stop its test and sends a alarm to notify you. Hope this helps. Get the manual and go into the ups and do a diagnostics on the UPS, this should identify if you have bad batteries or power modules are bad. Doing a diagnostics should not drop the load.

Ups off shows in the display of powerware9120 3000va


Was the UPS commanded to power down? Make sure there is nothing plugged into the UPS and disconnect it from whatever is powering it. Then pull out the all of the batteries inside of the UPS just enough to disengage them from their connections. Once everything has been unplugged and nothing has been feeding the UPS power - then go ahead and re-engage all of the batteries. Turn on the power source to the UPS. It should start up and function as before - you may need to instruct the UPS to carry the load.

Powerware 9120 BUS Unbalanced error display


I've had this same issue what it boils down to is that the Power IN is not being distributed properly across the Power Outlets.

Step 1. unplug everything from the unit and power the ups down. If the alarm clears itself the UPS is mostly likely fine. if it doesn't not clear send it in for repair

Step 2. If step 1 cleared the alarm try distributing the decives across the outlets differently.

There are two inverters so two output if everything is plugged into one side (ie a power bar with 10 things plugged into it) and nothing on the other side this could cause the alarm.

hope this helps
