      The intermittent beeping and illuminated 'Fault' LED on your Santak UPS usually indicates an issue with the load, power input, or battery connection. First, reduce the connected load to ensure it's within the UPS's capacity. Next, verify that your input wiring is correctly connected and the input voltage is within the normal range. Finally, check that the battery switch is on and the battery wiring is properly connected.
