(Volt-free changeover contact) indicating that the inverter is supplied by the battery in the following cases:

-normal AC source outage or voltage drop.

-rectifier/charger shutdown.

-rectifier/charger current limiting.

This signal, which may be used to initiate process saving and shutdown procedures, is time-delayed 30 seconds to avoid unnecessary operations following micro-breaks.
