4. Impostazione
This section guides you through the initial setup of your OONO PWRshield F-1009 module.
4.1. Installazione fisica
The module features mounting tabs for secure installation. Ensure it is placed in a location with adequate ventilation and away from direct heat or moisture.

Figure 1: Dimensions of the OONO PWRshield F-1009 module (all measurements in millimeters).
4.2. Collegamenti elettrici
Connect your power source and load using the provided 30 Amps Power Pole connectors. Pay close attention to polarity: Red is positive (+) E Black is negative (-).
- Connessione di ingresso: Connect your DC power source (e.g., battery, power supply) to the INGRESSO terminali.
- Connessione di uscita: Connect your load (e.g., radio, electronic device) to the PRODUZIONE terminali.

4.3. Initial Dip Switch Configuration
Before applying power, configure the LVD (Low Voltage Disconnect) and HVD (High Voltage Disconnect) trigger voltages using the dip switches located on the side of the module. Refer to the table in the Operating Instructions section for specific voltage impostazioni.

5. Istruzioni per l'uso
The PWRshield F-1009 offers flexible operation modes and voltage impostazioni di protezione.
5.1. Setting LVD and HVD Trigger Voltages
Use the four dip switches (SW1-SW4) to set the desired Low Voltage Disconnect (LVD) and High Voltage Disconnect (HVD) trigger voltages. Switches 1 and 2 control LVD, while switches 3 and 4 control HVD. Refer to the table below for specific configurations.

Figure 5: Dip switch configuration table for LVD and HVD trigger voltages.
5.2. Rocker Switch Modes (ON/AUTO/OFF)
The rocker switch on the front panel controls the output behavior:
- Modalità automatica: (Middle position) In this mode, the module operates according to the LVD and HVD settings configured via the dip switches. The output will automatically disconnect if the input voltage falls below the LVD trigger or rises above the HVD trigger. It will reconnect when the voltage returns to the safe operating range (LVD Restore/HVD Restore).
- Modalità ON: (Up position) Forces the output to remain ON, regardless of the input voltage. This bypasses the LVD/HVD protection. Use with caution, as it can lead to over-discharge or over-voltage damage to your connected devices.
- Modalità SPENTO: (Down position) Forces the output to remain OFF, regardless of the input voltage. This completely disconnects the load.
5.3. Indicatori LED
The module features three LED indicators for real-time status feedback:
- OVER (Yellow): Illuminates when the input voltage exceeds the High Voltage Disconnect (HVD) threshold.
- NORMAL (Green): Illuminates when the input voltage is within the safe operating range (above LVD and below HVD).
- UNDER (Red): Illuminates when the input voltage falls below the Low Voltage Soglia di disconnessione (LVD).

6. Manutenzione
The OONO PWRshield F-1009 module is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:
- Mantenere pulito: Periodically wipe the module with a dry, soft cloth to remove dust and debris. Avoid using harsh chemicals or abrasive materials.
- Controllare le connessioni: Regularly inspect all Power Pole connections to ensure they are secure and free from corrosion. Loose connections can lead to voltage gocce o funzionamento intermittente.
- Condizioni ambientali: Ensure the module is operated within its specified temperature and humidity ranges. Avoid exposing it to extreme conditions.
7. Risoluzione Dei Problemi
If you encounter issues with your OONO PWRshield F-1009 module, refer to the following troubleshooting tips:
- Nessuna potenza di uscita:
- Check if the rocker switch is in the 'OFF' position. Switch it to 'AUTO' or 'ON' as required.
- Verificare il volume immessotage is within the normal operating range (not triggering LVD or HVD). The 'OVER', 'NORMAL', or 'UNDER' LEDs will indicate the current voltage stato.
- Ensure all Power Pole connections are secure and correctly polarized (Red to positive, Black to negative).
- Volume erratotage Cutoff/Reconnect:
- Double-check the dip switch settings against the provided table (Figure 5) to ensure they match your desired LVD and HVD trigger voltages.
- Confirm that the rocker switch is in 'AUTO' mode for the programmable protection to be active.
- Continuous Beeping/Alarm:
- A continuous or intermittent beep indicates a voltage condition (OVER or UNDER) that has triggered the protection. Refer to the LED indicators to identify the specific issue.
- The module has a built-in delay for disconnect/reconnect (e.g., ~5 seconds for low voltage disconnect/reconnect). This is normal behavior to prevent nuisance tripping from momentary voltage fluttuazioni.
- Switch Behavior Appears Reversed (ON/OFF):
- The rocker switch has three positions: 'ON' (up), 'AUTO' (middle), and 'OFF' (down). Ensure you are selecting the intended mode. 'ON' forces output, 'OFF' forces no output, and 'AUTO' enables voltage protezione.
