1.1
These requirements apply to drive machine controllers, logic controllers, and
operating devices accessory thereto, for starting, stopping, regulating,
controlling, or protecting electric motors, generators, or other equipment, for
elevators, escalators, moving walks, dumbwaiters, and elevating devices for the
handicapped (wheelchair and stairway lifts).
