NOTE:
In ACC On mode, the Power 1 connector must connect to the ACC on
signal to be able to control system power.
The ACC On mode is designed for vehicle applications. When the TANK-700 is in ACC
On mode, the main power input is the Power 1 connector and the backup power is from
the Power 2 connector.
