The product image below shows the main unit and its components.

Image: The FERVE F918 battery charger, a red and white unit with a digital display showing "12.5". It has control buttons for voltage (V) og amperage (A), and switches for 10A/20A and 12V/24V. Red and black battery clamps are connected to the front. Safety icons are visible on the top right of the front panel.
3. Opsætning
- Udpakning: Tag forsigtigt opladeren ud af emballagen. Undersøg den for tegn på skader.
- Placering: Place the charger on a stable, flat surface in a well-ventilated area, away from direct sunlight, heat sources, and flammable materials.
- Batteriforberedelse: Sørg for, at batteripolerne er rene og fri for korrosion. Rengør dem om nødvendigt med en stålbørste.
- Tilslutning til batteri:
- Tilslut rød (+) clamp til den positive (+) pol på batteriet.
- Tilslut sort (-) clamp til den negative (-) pol på batteriet.
- Sørg for, at forbindelserne er sikre.
- Strømtilslutning: Only after connecting the clamps to the battery, plug the charger's power cord into a suitable 230V AC outlet.
4. Betjeningsvejledning
4.1. Opladning af et batteri
- Vælg Voltage: Brug voltage selector switch (red rotary knob) on the front panel to choose between 12V or 24V, matching your battery's voltage.
- Vælge Ampalder: Brug 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.
- Skærm skærm: Det digitale display viser den aktuelle lydstyrketage og amperage during charging.
- Opladningsproces: The charger will automatically begin charging. Monitor the display for progress. Charging is complete when the amperage draw significantly decreases or the voltage stabiliserer sig.
- Afbryder forbindelsen: Once charging is complete, first unplug the charger from the AC outlet, then disconnect the black (-) clamp, efterfulgt af den røde (+) kl.amp fra batteriet.
4.2. Testfunktion
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. Vedligeholdelse
- Rensning: 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.
- Opbevaring: Store the charger in a cool, dry place when not in use. Keep the cables neatly coiled.
- Kabelinspektion: 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.
- Udskiftning af sikring: 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).
6. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Opladeren tænder ikke. | No power from outlet; loose power cord; internal fuse tripped. | Check outlet with another device; ensure power cord is securely plugged in; if "AUTO-FUSE" is indicated, allow time for reset or consult service if persistent. |
| Batteriet oplades ikke. | Forkert voltage/amperage selection; poor battery clamp connection; battery is severely discharged or faulty. | Verify 12V/24V and 10A/20A settings; ensure clamps are clean and securely attached; test battery condition separately. |
| Digitalt display virker ikke. | Strømproblem; intern fejl. | Kontroller strømforbindelsen; hvis problemet fortsætter, kontakt kundesupport. |
