20 Most Recent Eaton PW9390 UPS System Questions & Answers


You definitely want to follow the manual procedure to avoid a possible load loss:

http://powerquality.eaton.com/Products-services/Backup-Power-UPS/9390.aspx?cx=3

9.1.4 Transfer from Normal to Bypass Mode
To transfer the critical load to Bypass mode:
C A U T I O N
In Bypass mode, the critical load is not protected from commercial power interruptions and abnormalities.
1. Press the CONTROLS pushbutton on the main menu bar. The System Controls
screen appears.
2. Press the BYPASS pushbutton on the System Controls menu bar.
The UPS transfers to Bypass mode and the critical load is immediately supplied
by the bypass source. If the bypass source is not available, the power processor
remains on and an alarm sounds.
3. The UPS is now operating in Bypass mode and the BYPASS status indicator is
illuminated.
The power module (PM) status indicates READY. The system is now on bypass
and the UPS power processor remains on.


At this point, you can operate an external bypass switch to get to maintenance bypass if needed.

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.
