The U/V ACTIVE ONLY IF BUS ENERGIZED settings may be used to prevent nuisance alarms
or trips when the bus is not energized. If this settings is programmed to “Yes”, at least one
voltage must be greater than 20% of the nominal nameplate voltage rating for any alarm/
trip. If the load is high inertia, it may be desirable to trip the motor off-line or prevent it from
starting in the event of a total loss of line voltage. Programming “No” for this settings
ensures that the motor is tripped and may be restarted only after the bus is re-energized.
