Safety Information
WARNING: This equipment employs components that tend to produce arcs or sparks. To prevent fire or explosion, do not install in compartments containing batteries or flammable materials.
CAUTION: To prevent fire, do not mount in zero clearance compartments. Do not cover or obstruct ventilating openings. Overheating may result.
Always ensure proper ventilation around the converter. Installation should be performed by a qualified individual in accordance with all applicable electrical codes and manufacturer instructions.
Setup and Installation
The WF-8725 is designed for straightforward installation. Ensure all power sources are disconnected before beginning installation.

AC Wiring
- Panel Input: Connect to a 105-130VAC, 60Hz, 5.5A, 670W source.
- Main AC Breaker: The unit accommodates a 30 Amp main AC breaker.
- Branch AC Circuits: Up to three 20 Amp branch AC circuits can be installed.
- Acceptable Filter Plates:
- Cutler Hammer Bryant: type FP-1B
- ITE/Siemens: type QF3
- Thomas & Betts: type FPTB
- Square D: type QO30
- Tightening Torque: Tighten AC Neutral and Ground connections to a maximum of 35 in-lbs. Refer to circuit breaker markings for AC Hot connections.
- Short Circuit Current Rating: The panelboard has a 10,000 RMS Symmetrical Amperes / 120 Vac rating. Replacement circuit breakers must match the original type and interrupting ratings.
DC Wiring

Image Description: This image shows the rear of the WFCO WF-8725 Power Center Converter, focusing on the DC output wiring connections and important safety warnings. The wiring diagram specifies the color codes for positive (blue, yellow, green, red) and negative (white) DC appliance connections. Prominent warnings advise against installation in compartments with batteries or flammable materials, and emphasize the need for unobstructed ventilation to prevent overheating.
The unit provides four DC circuits. The wires are labeled for easy identification:
| Wire Color | Function | Circuit |
|---|---|---|
| BLUE WIRE | Positive for DC Appliances | #1 |
| YELLOW WIRE | Positive for DC Appliances | #2 |
| GREEN WIRE | Positive for DC Appliances | #3 |
| RED WIRE | Positive for DC Appliances | #4 |
| WHITE WIRE | Negative |
DC Output Fuses: Use automotive type fuses. The internal label specifies fuse ratings (e.g., 15A, 20A, 15A, 15A for DC circuits and a 30A reverse polarity fuse). Always replace fuses with the same type and rating.
Tightening Torque: All connections should be tightened to 10 in-lbs.
Operation
Power On/Off
Once properly installed and wired, the converter will automatically provide 13.6 VDC output when connected to an AC power source. The cooling fan will activate only when needed to maintain optimal operating temperature.
Battery Charging
The WF-8725 features an automatic three-stage battery charging system:
- Bulk Mode (14.4 VDC range): Rapidly recharges deeply discharged batteries.
- Absorption Mode (13.6 VDC range): Safely charges the battery to nearly full capacity.
- Float Mode (13.2 VDC range): Maintains the battery at a fully charged state, preventing overcharging and extending battery life.
DC Circuit Indicators
The four DC circuits include LED lights that illuminate to indicate an open circuit, simplifying troubleshooting.
Maintenance
- Ventilation: Regularly inspect the converter's surroundings to ensure ventilation openings are not obstructed. Clear any dust or debris that may accumulate.
- Fuses: Periodically check the DC output fuses and the reverse polarity fuse. If a fuse is blown, replace it with an automotive type fuse of the exact same amperage rating.
- Connections: Ensure all AC and DC wiring connections remain tight. Re-tighten if necessary, adhering to specified torque values.
Troubleshooting
- No DC Output:
- Check the main AC power supply to the converter.
- Verify that the AC main breaker is not tripped. To reset a tripped AC breaker, switch it to the OFF position, then back to ON.
- Inspect DC output fuses for any blown fuses. Replace as needed.
- Check the reverse polarity fuse. If blown, it indicates incorrect battery connection. Correct the polarity and replace the fuse.
- Battery Not Charging:
- Ensure the converter is receiving AC power.
- Check all DC connections to the battery for tightness and corrosion.
- Verify the battery itself is in good condition.
- Overheating:
- Ensure the converter's ventilation openings are clear and not obstructed.
- Confirm the unit is not installed in a zero-clearance compartment.
- Interference with other electronics: The WF-8725 is designed to comply with FCC Class B standards. If interference occurs, ensure proper grounding and check for loose connections.
