3. Installation and Setup

Proper installation is crucial for the safe and efficient operation of your WFCO Power Center. It is recommended that installation be performed by a qualified technician.

Safety Precautions:

• Always disconnect shore power and battery power before beginning installation.
• Ensure proper grounding for both AC and DC systems.
• Verify all wiring connections are secure and correct according to the provided diagrams and local electrical codes.
• Refer to your RV's electrical diagrams for specific wiring requirements and component locations.

Installation Steps:

1. Preparation: Before removing the old unit, take clear photographs of all existing wiring connections. Label each wire carefully (e.g., using small pieces of masking tape) to ensure correct re-connection to the new unit.
2. Mounting: Securely mount the WFCO Power Center in the designated location within your RV. Ensure adequate ventilation around the unit to prevent overheating.
3. AC Wiring: Connect the incoming AC shore power wires (hot, neutral, ground) to the appropriate terminals within the power center's AC distribution panel. Ensure all connections are tight and properly insulated.
4. DC Wiring: Connect the DC output wires to your RV's 12V distribution panel. Connect the battery positive and negative wires to the designated terminals on the power center. Pay close attention to polarity (red for positive, white for negative).
5. Circuit Breakers and Fuses: Install appropriate AC circuit breakers and DC fuses as per the unit's specifications and your RV's requirements. Ensure correct amperage ratings are used for all circuits.
6. Final Checks: Double-check all wiring connections for correctness and security. Once verified, carefully restore battery power, then shore power. Verify proper operation of all connected appliances and the battery charging functions.

4. Operating Instructions

The WFCO WF-8735-AD Power Center features an advanced Auto-Detect technology that automatically identifies the connected battery chemistry (Lithium-Ion or Lead-Acid) and adjusts its charging profile accordingly. This eliminates the need for manual switches or settings.

Automatic Battery Detection:

• Upon initial connection of a battery or after a significant discharge cycle, the power center will analyze the battery type.
• For Lithium-Ion batteries, the unit will engage a multi-stage charging process optimized for LiFePO4 chemistry, typically charging at 14.6V in bulk mode.
• For Lead-Acid batteries, it will follow a standard three-stage charging profile (Bulk, Absorption, Float) to maximize battery life.
• The unit's internal indicator light (visible through a small opening on the unit, if applicable) may change color (e.g., green for Lead-Acid, blue for Lithium) to indicate the detected battery type.

Power Distribution:

The power center efficiently distributes 120 VAC to your RV's AC appliances via integrated circuit breakers. Simultaneously, it converts 120 VAC to 12 VDC to power your RV's 12VDC appliances and maintain the charge of the house battery.

5. Maintenance

Regular maintenance ensures the longevity and safe operation of your WFCO Power Center.

• Ventilation: Periodically inspect and ensure that the ventilation openings on the unit are clear and unobstructed. Do not block airflow, as this can lead to overheating and reduced performance.
• Connections: Annually or as needed, check all electrical connections (both AC and DC) for tightness and signs of corrosion. Loose connections can cause resistance, leading to heat buildup and potential failure.
• Fuses and Breakers: Inspect fuses and circuit breakers for any signs of damage or tripping. Replace blown fuses only with ones of the correct amperage rating as specified on the unit or in your RV's manual.
• Cleaning: Keep the exterior of the unit clean and free of dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners, solvents, or abrasive materials, as these can damage the unit.
