APC SURT3000XL UPS shows red error light, does not charge

Check battery and charging voltages. APC says 90% of faults are a dead battery. My experience also

Is red light on for overload or for battery?
If on overload, try reducing the load on the UPS. If red light on overload persists buy a new UPS (overload fault hard to repair).

Red light on battery - replace the batteries.

Red light on boost or buck, may mean that the nominal voltage of ups and the limits need to be changed/corrected.

The battery inside the APC is "weak", and the "beep" is telling you to replace the battery inside the APC, or, maybe cheaper, to buy a new APC.

check the fan in the back .... try to replace if damaged

The fault indicator means that there is a fault in the circuitry of the UPS. It could be the control board or another part of the system. (If the batteries were bad, you would see the Replace Battery light illuminate.) If the SURT3000XL is under warranty, contact APC. The standard warranty period is 2 years for repair/replacement. Note: you'll probably have to pay for the shipping of the unit. If the unit is out of warranty, replace it with a new UPS.

I hope this helps.

it is cause by UPS internal fault, possibilities like faulty charging circuit, inverter, etc.. you can call APC and check if its still have warranty, APC will replace it right away :D

1. Four beeps every 30seconds (On Battery LED will be illuminated)
This alarm indicates that the Battery PowerSupplied outlets are now supplying battery power as opposed to power from theutility. If the UPS determines that the input utility power is unsafe for yourcomputer equipment, the UPS will switch to battery power.
Note: Ifthe power disturbance is brief, you may only hear one or two beeps.

2. Continuous Beeping (On Battery LED will beilluminated)
This alarm indicates that a Low Batterycondition has been reached and that the UPS will soon shutdown. Once the UPStransfers to On Battery operation, it can only stay on battery for a limitedamount of time. The UPS will sound this alarm about two minutes before thebatteries are totally exhausted. Once exhausted, the UPS will shutdown and turnoff its output power to your equipment. If you hear this tone you shouldimmediately shutdown your computer to prevent data loss or corruption.

3. Continuous Beeps for 30 seconds (BackUPS OFFICE 250 and 280 ONLY)
This alarm indicates the unit has detected anOverload condition after it has performed a self-test during start-up.

4. Continuous Two-Tone Beep
This alarm indicates a severe Overload wasdetected while the unit was on-battery operation. This tone will continue tosound until the unit shuts down.

5. Continuous Tone (On Battery LED will beflashing)
This alarm indicates that the battery-poweredoutlets are overloaded.

6. Continuous Tone (On Line and On BatteryLEDs flashing) Back UPS OFFICE 350,400, and 500 ONLY
This alarm indicates that an internal UPS faulthas occurred.

If the device was still under warranty, you should call APC support and ask to send it in for repairs or replacement. Just keep politely asking, and ask to talk to their superior whenever they say it isn't possible and eventually you will get an RMA ticket/number.
If the device is not under warranty, you might be able to convince APC to service the device for a fee.

SY8KRFSH (why is this number so bogus?)_ RARE
or means not sold in USA. or canada...
I can not look up UPS outside USA or N;America
and no country told
nor your towns , AC power voltage. ratings

2002 MADE, NEW.
symmetra 8kva n+1 (sy8krfsh)?
8000 WATTS, MEDIUM SIZED, COMMERCIAL GRADE NOT FOR HOME USE.

the manual covers this.
it shows all error codes possible and causes
simple to harder.

the beep is even normal
at loss of utility power. 100% normal
unless turned off by you. it is a feature
other beeps mean hardware errors, battery bad tops that list.
and lots more.
this old UPS has 4 LED status and LCD display to see errors
the manual covers the, im reading it now at APC. dot com.

see log view in LCD look there.
read the errors there.
the right far LED is marked FAULT if glows that means see logs
or run diagnostics from the LCD menu.
but find the right manual first.

or call APC on the phone
or call for service from them
or find a local UPS tech and ask for support.
