- Note: Current, power, speed, sound level, and life expectancy ratings are at nominal voltage.
*Automatic shutdown at locked rotor condition: Restart at power OFF/ON.
†L10 bearing life expectancy, relative humidity 5% - 90%, non-condensing: The point in time at
which 90 percent of a sample lot can be expected to survive. Failure criteria for life testing that
establishes this figure include a 20% reduction in speed or a 20% increase in operating current.
5. Interface
