Ups starts beeping

After some time that the UPS is switched on, it starts beeping. The voltage output is still ok, and if the input is switched off, the output voltage remains stable. but the buzzer remains on. Did anyone encounter this issue?
Thanks in advance

Is there any indicator lights ON showing the fault condition?
This could indicate that the battery has a low charge. Even if you switch off the mains supply and it switches over to the battery, the UPS may shut down after a short time as the battery power (charge) runs out.
If the battery is more than 3 years old then it may be due for replacement.

    No there are no indicator lights. No the batteries are fully charged. The Ups clicks once when mains is applied. If you then touch the on button you hear a buzzing sound.

NO VOLTAGE ON YELLOW PHASE


what caused the UPS to transfer to Bypass? could be inverter fault, would you please check your battery set, maybe the input power is outside the tolerance and causing UPS to discharge the battery set , as well when battery set reaches the end of discharge it is causing the UPS to transfer to bypass and there is something missing on the input yellow Phase.
if the above is not true check the load type that is connected to the UPS output that is causing UPS to switch off in 10 minutes time.

Tripping off of the Input protection


Need more info. What are the measurements on the input to the UPS. What is the total load you have? What other alarms are displaying? Check the input power to UPS. Also make sure the UPS is and will work for the correct voltage (Input of UPS) some UPS's are selectable voltages.

Smart UPS VT 10KVA fault "Mains Not Available. Input Freq/Volt Out of Range". All phases input and output giving the expected voltages 240V and frequency OK at 50Hz.


Sounds like you hooked up the input to the UPS on the bypass. Either way either way your input is not there. Also make sure you configure the UPS prior to placing online.

Site wiring fault


Hi Viqtah, (<------ Clever!!)

If you hit the ESC key and get to the main menu there is a Setup submenu. In there you can change the line voltage values coming into the UPS. Sometimes a previous owner will change those values and cause the UPS to fault when properly connected. NOTE: A CERTIFIED ELECTRICIAN SHOULD VERIFY ALL CONNECTIONS ENSURE PROPER PHASE ROTATION.

What does it mean by the beep sound from the UPS ES 350 unit?


Ok, 3-4 years is a much as you can expect from an ups battery so replacement is indicated. The beeps are letting you know the battery is not able to keep up with demand. So either you have recently added to the system or the battery/s failing.

UPS shuts off intermittently and beeps


More than likely it just needs a new battery. If the power is sagging (called a brownout) the UPS is trying to switch over to the battery to keep the power consistent. The beeping is probably a code that indicates there is an issue with low voltage on the battery. New batteries are around $20-25. Here's a link to the replacement battery: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Hope that helps.
