AC Draw Totals =______ =______ or =______ =______
The highest total of column A
and column B must be <
the
maximum AC current draw
allowed of 4.68A.
The highest total of column C
and column D must be <
the
maximum AC current draw
allowed of 2.68A.
* A DAA2-7525 used as a backup will draw the same power as a primary when it is active.
** When the amplifier is active, the column A charger entry must be 0.79 or the column C entry must be 0.58, no matter what size the charger is.
