20 Most Recent Eaton Powerware 9355 UPS System Questions & Answers


Bypass failure is the same as your input unless you have a dual input. You lost power and the UPS did not hold the load because the batteries are bad. Replace the batteries and you will be ok.

Seems to have had a power glitch, is the system back to normal?

it looks like you have a faulty static switch

Eaton Powerware... | Answered on Jan 05, 2015


it indicates you have a polarity issue on your bypass feed. Most likely L1, L2 or L3 are mixed up (rotated). So you are using L2 as L1 or something like that. You should check (measure) the phase rotation/polarity.

Hello Eugene

This is the only post that you have posted here on Fixya dot com, albeit you have posted this same thing twice. Therefore I suspect you asked the question elsewhere and then came here to complain about it!

I suggest you contact Eaton direct by phone.

UPS used lead acid batteries which die after 3 or 4 years. Disconnect the power and open it to see which ones it uses. You will know they are dead if they have swollen or melted. Buy replacement batteries.

learn that when you have black out.
the batteries TAKE OVER< and are huge stress on any battery like this,, and when the lights (AC power) turned the UPS tries to charge said batteries and are now bad.
time for new batteries, or let it beep for 24hours and hope the batteries can recover.
the manual tells you how to see if the batteries are bad and with errorcodes, on all UPS made. RTM read the manual first.
no 2 UPS are the same , unless are.
the first is battery voltage under charge, if too low that means
a cell in 1 battery is shorted. as the LOVE TO DO.

no UPS stated, model.
how old are you batterie(s)
charging errors of most kinds means the battery is bad.
they can do that even year old, but mine last about 3 years on avg.
no battery in any USB with Gel Cells, last a long time.
a fraction of all else inside the box. in fact.
buy a new battery and put it in.
