Page 3: General Information
The WF-9800LiS Series Converter-Chargers will charge the 12-volt house battery if installed. A battery does not have to be installed for WF-9800LiS Series Converter-Chargers operation. When a battery is installed, two reverse polarity fuses are installed to protect the converter circuitry. -

If this occurs, the unit will recover once loads are reduced. Short-Circuit Protection Should a short circuit occur in the RV, the WF-9800LiS Series Converter-Charger will drop the voltage output to zero volts. If the short-circuit condition is removed and no other fault conditions are detected, the converter will resume normal operation. -
Page 5: Circuit Protection
WF-9800LiS Series Converter-Charger Fuses DC Fuses (12 Volts) The DC fuse receptacle on the rear panel of the WF-9800LiS 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 OPERATIONAL FEATURES Lithuium Converter Modes Two-Stage Smart Charging The two-stage “smart” charger continuously measures the battery voltage output and regulates the amount of charge using two modes of operation: Bulk and Absorption mode. Converter Modes of Operation Understanding output voltages of a two-stage converter. Figure 3... -
Page 7: Bulk Mode
Bulk Mode: This mode is designed with 2 purposes in mind. First, to quickly restore the energy back into the battery. Second, to ensure the lithium cells inside the battery remain balanced. This is accomplished by boosting the output voltage to 14.6 VDC and allowing the maximum current to flow as required by the loads. -
Page 8: Troubleshooting Instructions
Troubleshooting the WF-9800LiS Series Converter-Charger Converter Output Voltage Before checking the WF-9800LiS 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 converter output voltage at the battery with a voltmeter. Place the meter probes on the disconnected battery cables;... -
Page 9: Reverse Polarity Fuses
Reverse Polarity Fuses If there is no DC output coming from the WF-9800LiS 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. If no breaks are found, use a continuity tester to check for continuity. -
Page 10: Installation Instructions
The front of the enclosure should not be obstructed to allow free air flow for the cooling fan (Figure 6). An 8AWG copper conductor shall be used to bond the WF-9800LiS Series Converter-Charger to the vehicle frame. -
