Page 3: Safety Information
All wiring must conform to local, national and regional codes and regulations. Use copper conductors ONLY for all wire connections. Do not exceed the electrical ratings for the WF-9800-AD Series Power center or the equipment connected to it. Failure to follow these precautions may cause permanent failure and/or electrical shock which could result in severe personal injury or death. -
Page 4: Automatic Cooling Fan
AUTOMATIC COOLING FAN The cooling fan in the WF-9800 Series Converter-Chargers is controlled by the current (Amperage) load attached to the converter, NOT by temperature. The on-board microprocessor increases fan speed as the total load increases and decreases fan speed as the load decreases. Unlike traditional temperature-controlled fans, the load-controlled fan provides better component cooling by avoiding temperature spikes which can lead to premature component failure. -
Page 5: Circuit Protection
CIRCUIT PROTECTION WF-9800-AD Series Converter Charger Fuses DC FUSES (12 VOLTS) The DC fuse receptacle on the rear panel of the WF-9800 Series Converter-Charger has space for 1 (one) or 2 (two) Reverse Battery Protection fuses. These fuses should be replaced with ATC or ATO auto- motive type fuses, such as Littelfuse type 257 or Bussmann type ATC. -
Page 6: Operational Features
LED INDICATORS WFCO converters have integrated LEDs which inform the user on which mode it is in. As it pertains to charging profiles, green is intended for the lead-acid charge profile while blue is intended for the lithium charge profile. The most important light of them all for charging is red, which signals bulk charge mode. -
Page 7: Storage Mode
STORAGE MODE The third mode of charging is what is called the “float” charge. This mode is designed to provide a “trickle charge” to the battery after the system observes no significant variations in current draw over a long period of time. When in Storage Mode, the voltage will reduce from 13.6V to 13.2V and supply the “trickle charge”... - Page 8 - Converter size – A 55-amp converter can charge a battery faster than a 35-amp converter. The charging profile is not set in stone. WFCO Auto-Detect converters monitor the current over time at the end of every charge cycle. So, in the event of a misdetection due to external factors, once the factors are addressed or no longer present, the converter can still properly detect the battery type during the next charge cycle.

TROUBLE SHOOTING INSTRUCTIONS Troubleshooting the WF-9800-AD Series Converter-Charger Converter Output Voltage Before checking the WF-9800 Series Converter-Charger output voltage, disconnect the battery cables at the battery. Make sure the converter is plugged into a live AC source (105-130 Volts). Check the con- verter output voltage at the battery with a voltmeter. -

GENERAL COMPLIANCE INFORMATION Agency Listings The WF-9800 Series Converter-Chargers are UL-Listed, and cUL-Listed (Canadian). FCC Compliance Class B NOTE: This equipment has been tested and found to comply with the limits for a Class B digital de- vice, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protec- tion against harmful interference when the equipment is operated in a commercial environment. -
Page 11: Installation Instructions
Installing the WF-9800-AD Series Converter-Charger Mounting the Enclosure The WF-9800-AD Series Converter-Charger enclosure should be mounted in an accessible area such as a wall or in the side of a cabinet. Select a mounting location near the shore power and battery (bat- teries), in an area where the owner is unlikely to store items as this could reduce clearance require- ments, obstruct ventilation openings and affect the performance of the converter. - Page 12 DC Connections Connect a Red 8 AWG wire to the POS+ lug on the distribution center’s fuse board. Make sure this lug is torqued properly. In a similar fashion, connect a Black 8 AWG wire to the NEG- lug on the distribution center’s fuse board.

Questions and answers
I have a WFCO 65 AMP Power converter . WF-9865 .Always ran at 13.6 volts . Now it goes up to 14.7 volts and will not shut off . Do I need to rest something or replace the converter . Thank you Russ Rhodes
A WFCO 65 AMP Power Converter WF-9865 may increase voltage to 14.7 volts due to entering Charge Mode when the output current reaches its maximum, typically caused by a heavily discharged battery. In this mode, the converter targets 14.4 VDC, but due to the voltage-current relationship, the actual voltage may increase as the load decreases. If the voltage reaches 14.7 volts and does not return to normal, it could indicate a malfunction in the converter’s regulation circuitry or a faulty battery not reducing load as expected.
