Question about Energizer ER-PRO1000 1000 VA Tower Battery Back-up System (ENEERPRO1000) UPS System

1 Answer

UPS does not provide output power to outlets when turned on.

Unit does not provide power to computer connected to it when it is plugged in and turned on (relays sound as if they energize and Green LED indicator turns on) plus battery supported power is 92VAC (non-RMS DVM) only. PCB readings show that the unit provides no power to wired pads when plugged in and turned on however the battery provided 90.2VAC is present at the PCB pads. Is there a schematic available?

I've never seen a schematic for this. It's difficult to diagnose online but I would look at the primary circuit before the inverter. Possibly one or more bad caps or the inverter itself. Good Luck

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.

  • Read more:
  • 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.

    I am not sure on the outlets on the back of this unit.
    It is likely that the outlets on the back of the (UPS) are labeled, some battery backup (UPS) and the rest are surge protection only (no UPS).
    Of the 3 UPS units I have, on each unit, only about half of the outlets give UPS protection.
    The rest are surge protection.

    Hi,do I have to keep my ups plugged to a wall socke all the time?

    the unit needs to be plugged in all the time. the unit is or should be fully automatic. higher priced units have a usb cord so you can check their status right on the computer, does your ups have a usb outlet? you might want to take it up to a computer store and buy a usb cable and then you can control your UPS with your computer. manually turning the UPS on and off shouldnt hurt anything.
    good luck

    Need information

    The Back-UPS is fairly straight-forward. The 9-pin connector (at the top of the back) is a serial port (RS-232) for the UPS data (when connected to a computer it will shut down the computer safely during a power outage). The next plugs are RJ-11 telephone jacks; the cord from the jack (wall) goes in on the left (some models have RJ-45 for network protection). The battery protected outlets are the three surrounded by black paint. The other three provide surge-protection only. Do not plug items like printers and scanners into the outlets that provide battery protection.

    I hope this helps.

    When the power button is turned on my apc350 makes a high squeal sound, what is this? I have to have it turned on to use anything that is plugged into the battery backup outlets.

    Double check the connections on the internal battery. If you have had the unit for a year or longer it may be telling you your back up battery isnt any good. I suggest replacing the battery, go here

    After a short power outage (resetting breaker) the protected outlets no longer provide power. Is there a way to fix or do I need a new UPS?

    The unit may need to recycle itself. Remove the loads and turn the unit off. Plug it back in, wait a bit, then turn it on. Then try your loads on it again.
