SOURCE: APC ES350 strange noise

My solution was to unplug everything, hit the reset button, and then power the unit back up. The problem I found to be that I had my laser printer connected to the "surge + battery" side, and for some reason no laser printer can be connected to it.

SOURCE: APC back-ups es500 alarm continuously sounds why

It means it has an internal fault. if still under warranty period, just call APC and ask for replacement. if it out of warranty bring it to service center or better if you have to buy a new one because as far as i am concerned repair cost of this unit is much expensive than a new unit

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.

Hi, i have an APC UPS with model BE 500R PH how to bypass the auto shutdown of it?


On mine, until an electrical storm, was controlled through my computer via USB. Now, it shuts down in 5 seconds. I'm sure it's the thermistors, but I don't have time. Also, check for timing circuits.

Apc symmetra px stuck on self test


Place UPS into internal Bypass (Static Bypass) via the display. Then place unit back to Normal from Internal Bypass(Static Bypass). See if that helps. Or shut the unit down completely by placing UPS into Static Bypass first and then place UPS into external bypass mode, switch is located on the bottom front of the UPS. Please follow the UPS Manual to help you understand the procedures. Also recommend doing this after hours, not during business hours.

Contact APC.com
Here is the page for your model , it looks like it qualifies for the tradeups program. Or you can purchase a battery for it and fix it yourself.

APC ES500 switches off and the red light blinks. The problem started after I changed the the old battery. It had worked flawlessly with the previous battery.


The battery for this unit is an APC# $^ (RBC46)
Also known as a UB-1280 (12 volts 8.0 AH- amp-hour)

Did you add a greater load ... like a small "heater"?
Remove most of the plugs for what is plugged into it and try again.

If you have a "printer" plugged into it, unplug it, from the "protected" side. It belongs on the "surge" side of the APC Battery backup.

Hope this helps!

My APC back-ups es500 is keep on flashing in orange and green having the beep sound, whe it is on. It has been used for nearly 3 years. What would be the problem...?


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.

APC UPS 1500 w/full load forces immediate reboot at pwr failure


Hello,

With a 980watt load the run time is only 7 minutes on a brand new battery. If you have the system on full load your run time will be much less and it has likely damaged the battery. here is the APC web site page for your model. If you are running that much equipment I think you need either a bigger UPS or another 1500 and spread the load out.
