Shutdown
It is worth reminding that “auto-restart” means that the device will work intermittently as long
as the condition that is activating the function is not removed; “latched” means that the
device is stopped as long as the unit is connected to the input power source and the unit
must be disconnected for some time from the source in order for the device (and the unit) to
restart. Optionally, a restart can be forced by pulling the voltage of pin 16 (AC_OK) below
0.45 V.
