What to do if the ONEAC S07KXAU overload LED blinks and the buzzer beeps continuously?

  If the overload LED is blinking and the buzzer is beeping continuously, and the load is dropped, it means the ONEAC UPS is overloaded. This can occur if the overload is too large or lasts too long while the unit is on battery power. To resolve this, check the power drawn by the equipment and disconnect any short-circuited or non-priority devices. You may also need to restart the UPS.

What to do if the ONEAC S07KXAU UPS site wiring fault LED blinks and the buzzer sounds continuously?

  If the site wiring fault LED blinks, the red LED behind the ONEAC UPS is on, and the buzzer sounds continuously, it indicates a phase reversal (line and neutral) has been detected on the input power. If one side of the input power should be a grounded neutral (typically in 120 volts or 230 volt TN systems), have an electrician correct the reversal in the receptacle or power system. If neither side should be a grounded neutral (typically in phase-to-phase 208 volts or 230 volt TX systems), disable this function by pressing the push-button on the rear of the UPS between the fan and battery connector for five seconds. Note that disabling this function must occur within 30 minutes of the initial power up of the unit.

  If the overload LED blinks and the buzzer beeps once per second, the ONEAC UPS is in bypass, indicating an overload. This happens when the overload is too large or lasts too long while the unit is on AC power. Check the power drawn by the equipment and disconnect any short-circuited or non-priority devices.

  If the battery LED blinks and the buzzer beeps on your ONEAC UPS, it means a battery fault was detected during the automatic battery test. Check that the battery connector is properly seated. If the problem persists, replace the battery module.
