To ensure your SPS.HOME Uninterruptible Power Supply is functioning correctly, you can follow these steps:

1. **Check LED Indications:** The surrounding LED light near the On-Off button provides indications about the status of the UPS. Normal operation mode, mains failure, end of backup, and overload conditions are some of the statuses that can be indicated by the LED.

2. **Listen for Audible Alarms:** The UPS emits audible alarms to alert you of specific conditions. Beeps every 30 seconds in battery mode, beeps every 0.5 seconds for low battery, and continuous beeping for overload or failure are some of the audible alarm signals.

3. **Check Input Breaker:** The input breaker on the UPS can indicate whether the UPS is in a normal or tripped state. If the breaker is tripped due to an overload, you need to disconnect the load causing the overload, wait for 10 seconds, check the circuit breaker of the line supplying power to the UPS, and then restart the UPS.

If your SPS.HOME UPS is not working as expected, you can refer to the troubleshooting guide provided in the user manual. Here are some common issues and their possible solutions:

- **UPS backup time not as expected:** Ensure the battery is charged by connecting the UPS to a power socket and allowing it to charge for at least 8 hours. If the battery is damaged, contact the distributor or Technical Service and Support (T.S.S.).

- **UPS does not start:** Press the On-Off button to switch off the UPS and then switch it back on after 10 seconds. Ensure the UPS is connected to a power socket.

- **The SPS's output sockets do not supply voltage:** Check for a tripped breaker due to an overload. Disconnect the load causing the overload, wait for 10 seconds, check the circuit breaker, and then restart the UPS.

- **Power Master is inactive:** Ensure the serial port/USB cable is connected between the UPS and the computer. Use the cable supplied with the unit.

If the issue persists after attempting these solutions, contact the distributor, seller, or the Technical Service and Support (T.S.S.) for further assistance.
