Once the frequency of the phase AN or AB voltage (depending on wye or delta connection) is out of range of
the overfrequency and underfrequency setpoints, a trip or alarm will occur.
This feature may be useful for load shedding applications on large motors. It could also be used to load shed
an entire feeder if the trip was assigned to an upstream breaker.
