I think the requirement is for "low voltage release", where the equipment must be manually reset and restarted after loss of power, sometimes this is called "prevent unmonitored equipment startup". Simply having a magnetic starter is not sufficient to provide this protection. A magnetic starter must be wired with 3-wire control (i.e. momentary pushbuttons). This protection can also come from: a manual starter which includes a low-voltage release solenoid, a cord end GFCI that trips when the neutral is opened (i.e. Model 2500L from TRC), or a dedicated low-voltage protection device (i.e. Saf-Start from JDS Products).
