1. Introduction
The NJOY Aira 600VA is a Line Interactive Uninterruptible Power Supply (UPS) designed to provide reliable power backup and protection for various electronic devices. With a 500 Watt output and pure sine wave technology, it ensures stable power delivery, making it ideal for sensitive equipment such as central heating systems, pellet stoves, computers, monitors, and other household appliances. This UPS safeguards your devices from voltage fluctuations and guarantees extended operation during power outages.
Key features include a real-time LCD display for monitoring UPS status, battery charge, and operational errors, as well as customizable autonomy through external battery connections. The unit supports selectable charging currents (10A or 20A) and offers protection against overloads and short circuits, along with a cold start function and charging capability in off mode.
2. Important Safety Instructions
Please read and follow all instructions carefully before installing, operating, or servicing the UPS. Keep this manual for future reference.
- Do not open the UPS casing: There are no user-serviceable parts inside. Refer all servicing to qualified service personnel.
- Avoid moisture and extreme temperatures: Do not expose the UPS to rain, water, or excessive humidity. Operate the unit in a well-ventilated area, away from direct sunlight or heat sources.
- Ensure proper grounding: Always connect the UPS to a grounded AC power outlet to prevent electrical shock.
- External battery safety: When connecting an external battery, ensure correct polarity (+ to + and - to -) to avoid damage to the UPS and battery. Use only 12V lead-acid batteries with capacities between 40Ah and 200Ah.
- Disconnect power before servicing: Before performing any maintenance or connections, ensure the UPS is disconnected from both the AC mains and the external battery.
- Do not overload: Ensure the total power consumption of connected devices does not exceed the UPS's rated capacity (500W).

5. Setup
5.1 Unpacking and Inspection
Carefully remove the UPS from its packaging. Inspect the unit for any signs of physical damage. If any damage is found, do not proceed with installation and contact customer support.
5.2 Connecting the External Battery
The NJOY Aira 600VA requires an external 12V battery (not included) for power backup. It is compatible with car batteries or deep cycle batteries with capacities ranging from 40Ah to 200Ah.
- Ensure the UPS is turned off and disconnected from the AC mains.
- Connect the red battery cable (positive, +) from the UPS to the positive terminal of your 12V external battery.
- Connect the black battery cable (negative, -) from the UPS to the negative terminal of your 12V external battery.
- Double-check that all connections are secure and that polarity is correct. Incorrect polarity can damage the UPS and battery.
5.3 Connecting to Mains Power
Plug the provided AC input power cable into the AC input socket on the rear panel of the UPS. Then, plug the other end of the AC input power cable into a grounded wall outlet.
5.4 Connecting Devices
Plug the power cords of your devices (e.g., central heating system, computer, monitor) into the two Schuko output sockets on the rear panel of the UPS. Ensure that the total power consumption of all connected devices does not exceed 500 Watts.
6. Operating Instructions
6.1 Turning the UPS On/Off
- To Turn On: Press and hold the Power/Set button on the front panel for approximately 3 seconds until the LCD display illuminates and the UPS emits a short beep.
- To Turn Off: Press and hold the Power/Set button for approximately 3 seconds until the LCD display turns off and the UPS emits a long beep.
6.2 LCD Display Information
The LCD display provides critical real-time operational data:
- Input Voltage: Displays the current voltage from the mains power supply.
- Output Voltage: Shows the voltage being supplied to connected devices.
- Battery Charge Level: Indicates the remaining charge of the external battery.
- Load Percentage: Shows the percentage of the UPS's capacity currently being used by connected devices.
- Status Indicators: Icons for AC mode, battery mode, fault conditions, etc.
6.3 Charging Current Selection
The NJOY Aira 600VA allows you to select the charging current for the external battery, optimizing charging time based on battery capacity.
- With the UPS turned on, briefly press the Power/Set button (do not hold).
- The LCD display will show the current charging setting, typically cycling between 10A and 20A.
- Release the button when your desired charging current is displayed. The setting will be saved automatically.
6.4 Cold Start Function
The cold start function allows you to power on the UPS and connected devices using only the external battery, even when there is no mains power available. To perform a cold start, ensure the external battery is connected and charged, then press and hold the Power/Set button for approximately 3 seconds.
6.5 Charging in Off Mode
The UPS can charge the connected external battery even when the unit itself is turned off, provided it is connected to the AC mains power supply. This ensures your battery is always ready for use.
7. Maintenance
7.1 Battery Care
- Regularly check the external battery terminals for corrosion. Clean them if necessary.
- Ensure the external battery is kept in a well-ventilated area.
- Monitor the battery's performance. If the backup time significantly decreases, consider replacing the external battery.
7.2 Cleaning
To clean the exterior of the UPS, use a soft, dry cloth. Do not use liquid cleaners, aerosols, or solvents, as these can damage the unit or create a shock hazard.
7.3 Storage
If the UPS is to be stored for an extended period, disconnect it from both the AC mains and the external battery. Store the unit in a cool, dry place, away from direct sunlight and extreme temperatures. It is recommended to fully charge the external battery every 3-6 months during storage to maintain its lifespan.
