The Extralink PIORUN UPS offers superior performance and versatility compared to standard offline UPS units, particularly for critical applications requiring longer backup times and pure sine wave output.
4. Setup
Follow these steps to set up your Extralink PIORUN UPS Inverter:
- Unpacking: Carefully remove the unit from its packaging and inspect for any damage.
- Placement: Place the UPS on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat sources, and moisture. Ensure adequate space around the unit for airflow.
- Battery Connection: Connect your external 24V battery (AGM, Gel, or LiFePO4) to the DC input terminals on the UPS. Ensure correct polarity: red cable to positive (+), black cable to negative (-). Warning: Incorrect polarity can damage the unit and battery.
- AC Input Connection: Plug the UPS's AC input cable into a grounded 230V AC wall outlet.
- Device Connection: Connect your devices (e.g., heating system, server, medical equipment) to the AC output socket(s) on the UPS.

5. Operating Instructions
Turning On/Off:
- To Turn On: Press and hold the 'ON/OFF' button for a few seconds until the LCD screen illuminates and the unit powers on.
- To Turn Off: Press and hold the 'ON/OFF' button for a few seconds until the LCD screen turns off and the unit powers down.
Understanding the LCD Display:
The LCD provides real-time status information. Use the 'FUNCTION' button to cycle through different display modes if available.

Figure 4: The LCD display showing real-time input voltage (INPUT AC), output voltage (OUTPUT AC), battery charge level, and connected load percentage.
- Input Voltage: Displays the incoming AC voltage from the grid.
- Output Voltage: Displays the outgoing AC voltage supplied to your devices.
- Battery Level: Indicates the current charge level of the connected 24V battery.
- Load Indicator: Shows the percentage of the UPS's capacity currently being used by connected devices.
Automatic Voltage Regulation (AVR):
The AVR function automatically stabilizes the output voltage to your connected devices, protecting them from fluctuations in the main power supply. This operates continuously when the unit is connected to AC power.
Battery Charging:
When the UPS is connected to AC power and an external battery, it will automatically charge the battery. The LCD will indicate the charging status. Ensure the battery is compatible and correctly connected for optimal charging.
6. Maintenance
Regular maintenance ensures the longevity and optimal performance of your UPS Inverter.
- Cleaning: Keep the unit clean and free from dust. Use a dry, soft cloth to wipe the exterior. Do not use liquid cleaners or solvents.
- Ventilation: Periodically check that the ventilation openings are not obstructed.
- Battery Care: If using lead-acid batteries, ensure they are kept charged. For LiFePO4 batteries, follow manufacturer guidelines for optimal lifespan. Avoid deep discharges where possible.
- Storage: If storing the unit for an extended period, ensure the battery is fully charged and disconnect it from the UPS. Store in a cool, dry place.
7. Troubleshooting
If you encounter issues with your UPS Inverter, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| UPS does not turn on | No AC input power; Battery not connected or discharged; Unit fault. | Check AC power source; Ensure battery is connected and charged; Contact support if problem persists. |
