The Freedom X 1200 automatically detects when shore power is
present and when it becomes unavailable or drops to less than
106 volts AC.
The transfer time can be set to two settings. For details see
Adjusting Feature Settings in Configuration Mode on page 1.

Operating During Transition Between Grid Mode and Battery Mode

Transitioning from Grid Mode to
Battery Mode
When the unit is operating in grid mode and shore power is lost,
the Freedom X 1200 has less than 20 milliseconds (default) to
switch to operating in battery mode (if the Power button is pressed
in the On position) and starts drawing power from the battery.
The operating mode indicator will change to Battery Mode and the
green Status LED for Battery Mode will light up.
However, if the Power button is in Standby, this transition does
not happen and the display panel turns off.
Transitioning from Battery Mode to
Grid Mode
When the unit is operating in Battery Mode and shore power
becomes available, the Freedom X 1200 begins a 20-second
countdown to verify the stability of the shore power. If shore
power remains stable for a 20-second countdown, at the end of
the countdown, the Freedom X 1200 will switch to shore power
mode within 20 milliseconds and start drawing power from the AC
source.
The operating mode indicator will change to grid mode and the
green Status LED for grid mode will light up.
