4. Setup Instructions

1. Unpacking: Carefully remove the protector from its packaging. Inspect the device for any visible damage. Do not use if damaged.
2. Power Connection: Insert the EU plug of the TOSVA-16 protector directly into a standard AC 110V or 220V EU wall socket. Ensure the connection is firm.
3. Appliance Connection: Plug the appliance you wish to protect into the EU socket provided on the front of the TOSVA-16 protector.
4. Initial Power On: Once connected, the device will power on automatically or require a press of the power button (if present, refer to Figure 3.1). The digital display will illuminate, showing current voltage and current readings.

5. Operating Instructions

The TOSVA-16 allows for adjustment of voltage and current protection thresholds. Refer to the control buttons on the front panel (Figure 3.1).

1. Display Readings: The digital display shows real-time voltage (V) and current (A) values. Indicators such as '>V', '<V', '>A' will light up to indicate over-voltage, under-voltage, or over-current conditions, respectively.
2. Setting Thresholds:
   • Press the SET button to enter setting mode. The display will flash, indicating the parameter that can be adjusted.
   • Use the UP (▲) and DOWN (▼) buttons to adjust the desired voltage or current threshold.
   • Press SET again to cycle through different parameters (e.g., over-voltage limit, under-voltage limit, over-current limit, recovery delay time).
   • After setting all desired parameters, wait a few seconds without pressing any buttons. The device will automatically save the settings and exit the setting mode.
3. Power Button: The power button (often marked with a circle and vertical line symbol) can be used to manually turn the output power on or off.
4. Protection Activation: If the voltage or current exceeds the set thresholds, the protector will automatically cut off power to the connected appliance to prevent damage. Once conditions return to normal and after a set delay time, power will be restored automatically.

6. Maintenance

• Cleaning: Disconnect the device from the power outlet before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Inspection: Periodically inspect the device and its connections for any signs of wear, damage, or loose connections.
• Storage: Store the device in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Do Not Disassemble: Do not attempt to open or repair the device yourself. This may void the warranty and pose safety risks.
