GENERAL INFORMATION
WF-68100-AD Series Converter-Charger Safety Features
REVERSE BATTERY PROTECTION
The WF-68100-AD Series Converter-Chargers will charge the 12-volt house battery if installed. A
battery does not have to be installed for WF-68100-AD Series Converter-Charger’s operation. When
a battery is installed, three 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
on the following page). This feature prevents permanent damage to the converter from a battery
connected into the circuit backwards. In addition to protecting the converter-charger, the reverse
polarity fuses are the main connection between the converter-charger and the DC fuse board of a
distribution center.
