The batteries need to be replaced. They probably have more than 3 years.
Replace the batteries and let the new ones charge fully for a day and your UPS will work like new after that.

First of all do you use a load that is over your ups capacity?
does it goes off in normal work, or in autonomy?

Good Luck

Powerware 9390 UPS error configuration and circuit breaker battery check

9390 Requires a UVR type battery breaker. Unfortunately a configuration error will require a service visit from a technician. The proprietary service software will have to be used to reset this.

The UPS in this office is out of order, message that appear on screen is 'UPS V OUT LIMITS' and 'Battery critical'

follow this steps and fix it. God bless you
Plug the battery backup into a working electrical outlet. If the battery backup turns on when the power button is pressed, then the problem may be that the previous electrical outlet is faulty. Proceed to step three. If the battery backup doesn't turn on, proceed to step two.
  • 2 Reset the circuit breaker on the battery backup. APC battery backups have a labeled circuit breaker button located on the unit near the phone line, fax line, USB, network and coaxial cable inputs. Press the button to reset the circuit breaker. Power on the battery backup by pressing the power button. If the battery backup powers on, proceed to step three. If the battery backup doesn't turn on, proceed to step six.

  • 3 Determine if the battery backup is charged and providing battery power. With the battery backup on and plugged into a working electrical outlet, plug a computer monitor into one of the battery backup outlets labeled "battery backup plus surge protection" on the battery backup. (APC power supplies have some outlets that provide only surge protection while the other outlets provide surge protection plus battery backup.) Turn the monitor on. Unplug the battery backup power cord from the wall outlet. If the monitor remains on, the battery is holding a charge, supplying electrical power and the battery backup is working properly. If the monitor goes off, proceed to step four.
  • 4 Charge the battery. Plug the battery backup into an electrical outlet and allow the battery to charge for 16 hours. This will fully charge the battery.
  • 5 Test battery charge. Once the battery is fully charged, repeat step three. If the monitor stays on when power is interrupted to the battery backup, the issue is solved and the problem resulted from an incompletely charged battery. If the monitor turns off when power is interrupted, the battery within the battery backup is faulty and needs to be replaced.
  • 6 Replace the battery backup unit. The unit itself is faulty. If the battery backup is under warranty, contact APC to request a replacement.

    APC UPS 500 and 600, both say (PowerChute) commercial power is off and running on battery when the commercial power is fine. They end up shutting down my systems. After a while they run normal.

    This is usually caused by a popped circuit breaker on the UPS. From the UPS Manual:

    Disconnect non-essential equipment from the
    Back-UPS. Reset the circuit breaker (located
    on the rear panel of the Back-UPS) by pushing
    the circuit breaker button fully inward
    until it catches.

    You can find the user manual here:

    Has started to beep whenever items plugged into

    If it's more than 3 years old, you probably need new batteries.

    If the beep started after plugging anything additional into the UPS, you may be in an overload state, and the beep is telling you that it's choosing to beep and not function as intended rather than smoking itself. Try unplugging a piece or two from it and see if the beep goes away. If not, probably just you're batteries giving out due to old age, they'll only give you 3-5 years.

    I need help in hooking up a new circuit breaker for my internet office 450. Does it matter which of the two wires I connect to the breaker?

    If there is only two wires, the breaker is a current sensing device which connects in series with the circuit. which wire goes where should not matter.

    My ups has is faulty i need a circuit diagram to fix it

    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.
