1.3.2 Front Panel Indicators
Circuit boards for the optional Smart AlphaGuard (SAG), Alpha APPS card and the two-output AlphaDOC are
located behind the removable front panel.
Smart AlphaGuard (SAG): Enables the XM3 to gather battery voltage data for up four battery strings (A through D).
Its Charge Management Technology applies excess charge current to batteries as needed to maintain balanced
voltages throughout the string. See
Section 1.3.4, Smart AlphaGuard
for connection information and LED
functionality.
Alpha APPS Card
Output 1 (White = Neutral, Black = Line): The AC output connector is clearly marked and color-coded for easy
identification. The Service Power Inserter (SPI) connects directly into the Output 1 connector.
Output 2 (White = Neutral, Black = Line): When no AlphaDOC is installed, this output is wired in parallel to Output 1
and is often used for auxiliary loads. If the AlphaDOC is installed, Output 2 can be isolated from Output 1.
