ELAC 2 is powered by battery 2 if normal power fails, but only for 30 seconds after which it is de-energized. This is presumably to cover a temporary loss of normal electrical power and to save batt 2 in case the loss is not temporary.
ELAC 2 is connected again to batt 2 when the nose gear is extended.
