What are the typical start-up and shut-down wind speeds for a turbine?

Some turbines release their brakes at wind speeds of 4-5 m/sec. The FutureWind range start operation at 2 m/s, thereby catching more energy in low-grade sites.Most turbines shut down for safety reasons when the wind speed exceeds 25 m/s. The FutureWind range shut down at 30 m/s, again to capture more wind.
