4. Installazione
The WF-8935-AD is designed as a compatible replacement for various WFCO and other power centers. Follow these general guidelines for installation.
4.1 Controlli pre-installazione
- Verify that the new unit's dimensions are suitable for the intended mounting location.
- Ensure all power sources (shore power, generator, battery) are disconnected.
- Inspect existing wiring for damage or corrosion.

4.2 Montaggio
Mount the power center in a dry, protected location. The zero-clearance design allows for installation without requiring extra space for side or rear ventilation. Ensure the front panel is accessible for wiring and fuse replacement.
4.3 Collegamenti di cablaggio
Carefully connect all AC and DC wiring according to your RV's electrical diagram and local electrical codes. Labeling wires before disconnection from an old unit is highly recommended.
- Cablaggio CA: Connect the main AC input, and then individual branch circuits to the appropriate breakers. The unit supports 1 main and 9 branch AC circuits.
- Cablaggio CC: Connect the battery leads (positive and negative) and then individual DC load circuits. The unit provides 9 x 20 Amp and 2 x 30 Amp DC circuits.
- Messa a terra: Ensure proper grounding of the unit to the RV chassis.

5. Funzionamento
Once installed and wired correctly, the WF-8935-AD Power Center operates automatically.
5.1 Accensione iniziale
After all connections are secure, restore battery power, then shore power. The unit will power on, and the converter/charger will begin its operation.
5.2 Auto-Detect™ Technology
The patented Auto-Detect™ Technology automatically senses whether a lead-acid or lithium-ion battery is connected. It then adjusts the charging voltage e attuale profile to match the battery type, ensuring efficient and safe charging without any manual intervention.
5.3 Funzionamento del ventilatore
The internal cooling fan is load-based, meaning it will only activate when necessary to maintain optimal operating temperatures. This design minimizes noise and extends the fan's lifespan.
6. Manutenzione
Regular maintenance helps ensure the longevity and reliable operation of your power center.
- Controllo dei fusibili: Periodically inspect DC fuses for continuity. Replace blown fuses with the correct ampvalutazione di età.
- Pulizia: Keep the power center's ventilation openings clear of dust and debris. Use a soft, dry cloth for cleaning the exterior. Do not use liquid cleaners.
- Ispezione della connessione: Annually, with power disconnected, check all electrical connections for tightness and signs of corrosion.
