Question about Powerware 5110 UPS System

Open Question

My PowerWare UPS does not charge batteries anymore.

Here is the test I made: - Unplug batteries - Power on the UPS - Replug the batteries, then we can hear a small "click" from the relay probably to start charging the battery. - Unplug the batteries again, the relay does not move. - When I measure from the batteries connectors, I have 22.5V on both the Battery side, and the UPS side (Disconnected of course). It seems that the charger is only sending 22.5V while we would expect 25V (2x12V batteries).

1st, the 9120 is a 700, 1000, 1500, 2000, 3000, 5000 or 6000 Va
if it is a 6000 Va that voltage sounds ok, and the ups as no problem, each battery will be around 12,75 Volts, it will be higher and the charging circle ends.

SOURCE: Hello, my Powerware 3105 beeps

Your problem is showing up under the Powerware 9305 (a very large UPS) but your comments are about the 3105. It sounds like your battery is dead. If your UPS is over 3-5 years old, that's most likely the case. The website address to view the user manual is www.eaton.com/3105 You can contact Eaton directly, too. Eaton bought Powerware about 6 years ago. Here's the contact info. Be sure to have your serial and model numbers ready from the rating label on your UPS.

SOURCE: Battery Packs for Powerware 9355 UPS

If you battery packs are all at 130volts DC, then all of the packs will have become dead, and the batteries are not recoverable. Your battery DC bus voltage on a Powerware 9355 20 to 40kVA rated UPS is nominal 432 volts DC - 36 batteries in series in each string at 12 volts DC per battery. If batteries go below 10.5 volts DC each, or 378 volts DC bus voltage, no amount of charging will recover these batteries. You should not be recycling the DC battery breaker, unless you felt the battery breaker was faulty. The UPS would have given you an alarm message of either battery breaker Off, Charger Failure, or Low DC Bus Voltage long before the these batteries failed.
The battery test will not proceed if the batteries are dead.

Did your UPS display "Battery disconnected" or did it display "Battery Failure"? If it was "Battery Failure", for some reason the Powerware 9120 will take almost 18 hours after plugging in to power after battery replacement to correct the Battery Failure indication. Charger has to charge up the batteries, followed by an automatic battery test by the UPS. If the indication was "Battery Disconnected", you will need to check the internal fuses to see if they are blown. If the UPS keeps blowing fuses, it will require a board repair.

Our UPS powerware 9335 cannot be on anymore, only bypass we are using.


It's hard to pinpoint the issue without more information. You may just need to replace the batteries. I encourage you to reach out to Eaton (Eaton purchased Powerware about 6 years ago). Here is the product page where you can download the manual: http://powerquality.eaton.com/Products-services/Backup-Power-UPS/9355.aspx?cx=3

Battery Packs for Powerware 9355 UPS


The Batts can be charged externally, then refitted, usually I extend the DC cables so I can work with the batt outside the unit. This is ONLY to be done if you understand the risk and what may happen if you get it wrong.

Batts are always live and can cause fire/explosion/severe burns if shorted!
IF YOU ARE NOT SURE THEN GET SOME EXPERIENCED HELP!

OK so the UPS will not normally recognise a very low batt pack, that is the reason you can not start the test, this test will back of the rectifier so the batt pack takes the load for a short period.

If the batt pack is out of range then this will make the load go off, so the UPS is designed not to allow the test,unless the batt is at the right level.

If you can get the batt pack up close to normal then the unit will recharge it to full.,Wait until it is fully charged before testing.
If this is sucessful the cyle the batt a few times allowing it to reach around low batt warning before recharging. This will assist the batt in recovery. During this process if possible monitor with a test intrument(fluke 123 or 43B will do) the batt pack discharge curve , once the batt pack has dropped to its charge level from float, it should be a smooth decay.
depending on the state of the batts you may be ok, if there are weak ones in the string then you may have to replace all of them depending on the age of the batt pack.

MAKE SURE YOU ARE VERY CAREFUL WITH BATTERIES, THEY ARE VERY DANGEROUS, AND ALWAYS LIVE!

Check you manual for safety procedures, BEFORE working on Batteries.


hope this helps

thanks for using Fixya

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

The UPS dont go to on batteri


Replace the batteries with new one then power the UPS without load for three hours or more so that the batteries can be charged. Then disconnect or switch off power to the UPS and observe if it will till be on using the batteries. If it will be ON then your problem is solved but if it goes off then your UPS is on BYPASS

Greetings!
How many years is your ups working? UPS is usually run by a battery, some of them are disposable and needs replacement. If it does not charge anymore it needs replacement of battery.
Thanks.
