Transitioning From Battery Mode To Shore Mode - Xantrex Freedom EX 4000 Owner's Manual

Operating During Transition Between Shore Mode and Battery Mode
Transitioning from Battery Mode to
Shore Mode
When the unit is operating in Battery Mode and shore power
becomes available, the Freedom EX 4000 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 EX 4000 will switch to shore power
mode within 20 milliseconds and start drawing power from the AC
source.
The AC source LED lights up and the Inverter LED turns off.
