5. Настройка і ўстаноўка
The WF-9875-AD-CB is a deck mount converter/charger. Follow these general guidelines for installation. Always refer to your RV's specific wiring diagrams and safety standards.
- Выберыце месца ўстаноўкі: Choose a dry, well-ventilated area for mounting the converter/charger. Ensure there is sufficient space for air circulation and access to connections. The unit should be mounted securely to a stable surface.
- Адключыць харчаванне: Before making any connections, ensure all AC power to the RV is disconnected at the shore power pedestal and the RV's main breaker. Disconnect the RV's battery terminals.
- Уваходнае злучэнне пераменнага току: Connect the AC input wiring from your RV's AC distribution panel to the converter/charger. Ensure proper wire gauge and secure connections according to electrical codes.
- DC Output Connections: Connect the positive (+) DC output terminal (red) to the RV's 12V DC distribution panel or battery positive terminal. Connect the negative (-) DC output terminal (black) to the RV's 12V DC ground bus or battery negative terminal. Ensure these connections are tight and use appropriate wire gauges for 75 Amp выхад.
- Зазямленне: Connect the chassis ground lug of the converter/charger to the RV's chassis ground.
- Fuse Installation/Check: The unit typically comes with pre-installed fuses. Verify that the correct 35 Amp ATO/ATC fuses are securely in place in the designated fuse holders.
- Аднавіць сілу: Once all connections are secure and verified, restore battery connections, then restore AC power to the RV.
Заўвага: If you are not experienced with electrical installations, it is highly recommended to seek assistance from a certified RV technician.

6. Інструкцыя па эксплуатацыі
The WF-9875-AD-CB converter/charger operates automatically once properly installed and connected to AC power and batteries.
- Automatic Battery Detection: Upon connection to a battery and AC power, the unit's patented Auto-Detect technology will identify whether a Lead-Acid or Lithium-Ion battery is connected. It will then automatically select the appropriate multi-stage charging profile. No user intervention is required for battery type selection.
- Мульты-Stagэлектронная зарадка: The converter/charger will provide optimal charging based on the detected battery type. This process ensures the battery is charged efficiently and safely, preventing over or under-charging, which can extend battery lifespan.
- Крыніца харчавання пастаяннага току: The unit continuously provides stable 12V DC power to your RV's electrical system, even when the battery is fully charged or not present.
- Праца вентылятара: The internal cooling fan is load-based, meaning it will only activate when the unit generates sufficient heat due to current draw. This ensures quiet operation during periods of low demand.
