GENERAL INFORMATION WF-9800 Series Converter-Charger Safety Features Reverse Battery Protection The WF-9800 Series Converter-Chargers will charge the 12-volt house battery if installed. A battery does not have to be installed for WF-9800 Series Converter-Chargers operation. When a battery is installed, two reverse polarity fuses are installed to protect the converter circuitry. The fuses are located on the rear panel of the enclosure near the AC power cord (refer to Figure 1 below).
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.
CIRCUIT PROTECTION WF-9800 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 (see Figure 1 above). These fuses should be replaced with ATC or ATO automotive type fuses, such as Littelfuse type 257 or Bussmann type ATC.
Figure 2 Note: The converter, while in Float Mode, will continue to supply a trickle charge to the battery. If the RV is in storage for any length of time, we recommend the battery and its fluid levels be checked every 3 weeks. Note: For a detailed explanation of the charging modes, please refer to our publication “Theory of Operation”, document #AD-TD-0001-0.
Figure 3 If the converter output voltage at the battery reads 0.0 VDC, or if the battery is not charging, check for an open inline fuse in the battery wire circuit. One may have been installed by the RV manufacturer. Also check for loose wiring connections. Reverse Polarity Fuses If there is no DC output coming from the WF-9800 Series Converter-Charger output lugs, first check the reverse polarity fuses on the rear panel. Then, visually inspect the fuses for any breaks in the fuse element.
Figure 4 GENERAL COMPLIANCE INFORMATION Agency Listings UL 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 device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
INSTALLATION INSTRUCTIONS Installing the WF-9800 Series Converter-Charger Mounting the Enclosure The WF-9800 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 (batteries), in an area where the owner is unlikely to store items as this could reduce clearance requirements, obstruct ventilation openings and affect the performance of the converter (Figure 5).
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. A battery IS NOT required for converter operation. The battery works in conjunction with the converter to supply DC power to the RV. A battery is typically only necessary if you do a lot of dry camping or have slide-outs and/or a leveling system.
