Red and black battery clamps are connected to the front. Safety icons are visible on the top right of the front panel.

3. Setup

1. Unpacking: Carefully remove the charger from its packaging. Inspect for any signs of damage.
2. Placement: Place the charger on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat sources, and flammable materials.
3. Battery Preparation: Ensure the battery terminals are clean and free of corrosion. If necessary, clean them with a wire brush.
4. Connecting to Battery:
   • Connect the red (+) clamp to the positive (+) terminal of the battery.
   • Connect the black (-) clamp to the negative (-) terminal of the battery.
   • Ensure connections are secure.
5. Power Connection: Only after connecting the clamps to the battery, plug the charger's power cord into a suitable 230V AC outlet.

4. Operating Instructions

4.1. Charging a Battery

1. Select Voltage: Use the voltage selector switch (red rotary knob) on the front panel to choose between 12V or 24V, matching your battery's voltage.
2. Select Amperage: Use the amperage selector switches (orange buttons) to choose between 10A or 20A, depending on the battery's capacity and desired charging speed. For larger batteries or faster charging, select 20A.
3. Monitor Display: The digital display will show the current voltage and amperage during charging.
4. Charging Process: The charger will automatically begin charging. Monitor the display for progress. Charging is complete when the amperage draw significantly decreases or the voltage stabilizes.
5. Disconnecting: Once charging is complete, first unplug the charger from the AC outlet, then disconnect the black (-) clamp, followed by the red (+) clamp from the battery.

4.2. Test Function

The FERVE F918 includes a test function to check the battery's voltage. To use this function, ensure the charger is connected to the battery but not necessarily to the main power supply. Select the "TEST" position on the red rotary knob. The digital display will show the current battery voltage.

5. Maintenance

• Cleaning: Disconnect the charger from all power sources and batteries before cleaning. Wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Storage: Store the charger in a cool, dry place when not in use. Keep the cables neatly coiled.
• Cable Inspection: Regularly inspect the power cord and battery cables for any signs of damage, fraying, or exposed wires. Do not use the charger if cables are damaged.
• Fuse Replacement: The charger features an "AUTO-FUSE" system. If the charger stops working, check the fuse. Refer to the diagram on the unit for fuse location and replacement instructions if applicable (though "AUTO-FUSE" implies self-resetting or internal, non-user-serviceable).
