SOURCE: My APC back-ups es500 is keep on flashing in orange and Green

Hello,

Probably the battery is drained. You should charge it first. And if the problem still persist, it could be that the UPS battery needs replacement.

SOURCE: Overload light in APC RS 800 UPS

it seems that the inverter circuit of your UPS is dying. the solution here is you have to open up the UPS and check the inverter circuit. to make easier, check the power mosfet if its leaking.

Turn it off and unplug it from the wall.
Open it up and make sure that the red and black wires are connected.
If they are the battery needs to be replaced. They are only good for 2-3 years. If you are not comfortable with my instructions, call APC for free support. (800) 555-2725

Vote for this solution if it helps.

SOURCE: In My APC UPS, continuous beep sound is coming

Unfortunately that signals an internal fault with the UPS and it requires immediate replacement / repair. Do not continue to use the UPS at all.

Apc xs800 new batteries


I Bought two RBC32's and had to hook them up to the connector and did it wrong on the first try. Make sure you connect the yellow to the Red terminal on one battery and the Black on the other, then connet the remaining red to red on one and black to black to the other. Once I did that and plugged it back in everything worked fine.

Alternating green and orange light with constant beeps


Verify that the usb to ups cable is pluggled in properly. Also you may not have a good ground. Disconnect the ups and plug it in another outlet to test with nothing else plugged into it, to see if it still beeps. You can also try and upgrade the ups software from apc.com

The 'ON BATTERY' light goes on every so often and the unit beeps. Very annoying as this is not an overload so I want it silent.


Hello.

There might be several reasons for this:

1) Malfunction of your UPS' circuit
2) Damaged wire cord
3) The power on your wall socket fails too often
4) Most likely the batteries are exhausted. See the UPS' manual about batteries replacement.

Good luck

After a power outage my apc has this clicking sound. every 4 seconds or so it sounds like it clicks and then a slightly different click 4 seconds later. However, when everything is powered up it doesn't...


I found this on the APC website;
Question: What would cause a Back-UPS Pro, a Back-UPS Pro USB, a Back-UPS RS, a Back-UPS CS, a Back-UPS LS, or A Back-UPS XS to beep once every 5 seconds with no output power?
Answer: One beep every 5 seconds is an indication that the UPS has entered what is called "Low Voltage Sleepmode".
The Back-UPS product has transferred to battery power due to a low voltage condition at the wall. The Back-UPS has remained Onbattery until its runtime was totally exhausted, however, there was still enough voltage present at the wall to trickle charge the battery.

This is considered to be a normal operating state. When the voltage returns to normal the Back-UPS will wake up and restore power to the battery outlets.
