I have a power ware UPS which is given error`" D.C bus fault". Details of the UPS are as follows Power Ware 9120 6000i P/N 1026104

it's an internal ckrt error you need to have a dealer repair it. unless you know how to troubleshoot electronics and read schematics. there is no quick fix.

Hi guys, I just replaced 40ah x36 batteries, 12v into 40kva ups. With my cal, it suppose to back for about 40min at 60% loading. But now my client said they only have 10min back up. What may be wrong? Please help out

check and flip the reset button
if it still is faulty have it repaired or replaced

why don't you check the DC bank capacitors, you may need to replace them

There is no Galaxy 3000

Check to make sure your connections are correct and tight.

If you need UPS, Surge, or Power Related help contact Daniel @ Power & Systems Innovations 800.260.2259 or go to our website: http://psihq.com/

a red alarm on a ups normally means the batteries are dead. you will need to order and replace the batteries in the UPS.

Thanks

Power ware has a powerpass bypass switch for $200.00.

There is two inputs on this bypass switch. One for power, and one for the generator.

One ouput for your UPS. There you have it... There is your soluiton. I might add one other thing called a Power Guard, PMM117, to monitor the power of the backup generator. The time delay of this device will prevent over current from cooking your UPS power supply.

They also have a Hardwired version that is more expensive for you 5, 6 ,10KVA UPS. So a automatic bypass switch is what you need.

I had a DC bus fault error displayed.

So I unplugged battery, then turned on UPS. It said Batt disconnected of course.

So when I plugged in the batt while the UPS was on, and held the power button for a few sec, the UPS displayed Batt testing.

After a few moments it was back online and had no faults!

Worth a shot.
