AUTO-DETECT: WF-9500-AD SeriesThe WF-9500-AD Series Power Centers will charge the 12-volt House battery if installed. A battery does not have to be installed for WF-9500-AD Series Power Center converter operation. When a
battery is installed, two reverse polarity fuses are installed to protect the converter circuitry. The fuses are located along the bottom edge of the DC fuse board near the VCC+ lug (refer to figure 1 on page 4). This feature prevents permanent damage to the converter from a battery connected into the
circuit backwards. Blown polarity fuses are indicated by an illuminated Red LED near the lugs. In addition to protecting the converter section, the reverse polarity fuses are the main connection between the converter and the DC fuse board.
