The WF-8950L2-REP Converter Replacement Kit allows easy upgrade of existing power centers. Technicians can easily remove the lower section of certain power center brands and slide in the WF-8950L2-REP unit. This exchange upgrades the old single stage charger to a high performance three-stage charging powerhouse.
Reverse Polarity Fuses located on the fuse board to disconnect the converter section from the rest of the RV’s DC power. In order to install the WF-8950L2-REP Kit, you must first remove the existing converter section in your power center. This kit can be used on several different products.
11. Remove the (4) screws holding the converter (MBA) frame to the housing. 12. Slide the converter MBA and frame out of the housing. Note: The new WF-8950L2-REP comes with a new fuse board and hardware package. Installation of the WF-8950L2-REP is divided into 3 segments: •...
15. Replace the door assembly using the screws provided 16. Turn all breaker on and apply 110volt power to the RV. Test for operation. TROUBLESHOOTING INSTRUCTIONS Troubleshooting the WF-8950L2-REP Series Refer to the WF-9850L2 Troubleshooting Guide for the WF-9850L2 Deck Mount found on page 11 of this manual.
Automatic Cooling Fan The cooling fan in the WF-9850L2 Converter-Charger is incremental and is controlled by the current drawn out of the converter to the applied load. The on-board microprocessor increases fan speed as the total load increases and decreases fan speed as the load decreases. Figure 2 Unlike traditional temperature-controlled fans, the load-controlled fan provides better component cooling by avoiding temperature spikes which can lead to premature...
OPERATIONAL FEATURES Converter Operation 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 modes. Converter Modes of Operation Understanding output voltages of a two-stage converter. Figure 3...
Absorption Mode This mode is designed with 1 purpose in mind. This purpose is to provide a safe operating voltage for all loads in the RV. This is accomplished by reducing (from bulk mode) the output voltage to 13.6VDC and remaining at this voltage until the power is cycled to the converter.
Converter Output Voltage Before checking the WF-9850L2 Converter-Charger output voltage, disconnect the battery cables at the battery. Make sure the converter is plugged into an 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;...
If the above checks have been made but the converter output still reads 0.0 VDC, the converter is not functioning properly.
