9 3 Validity The power curves apply under the following conditions: Turbulence of approx. 10 % to 15 % Standard atmosphere according to DIN ISO 2533, at mean sea level (Air density kg/m 3 ) The nominal power refers to the low-voltage side of the transformer. Information on the influences of the cold weather adaptations on the power curves can be found in the supplement to the technical description and specification "Cold Weather Adaptations". 4 Cut-Out and Re-Cut-In Wind Speeds 4.1 GE 1.5s with WZ II Tower If the average wind speed exceeds 22 m/s in a 600 s time interval 25 m/s in a 30 s time interval or 27 m/s in a 3 s time interval the wind turbine generator system will shut down. If the average wind speed remains below 19 m/s in a 300 s time interval the wind turbine generator system will cut in again. 4.2 GE 1.5s and 1.5se (with IEC TC II / WZ III tower for 1.5s and with IEC I tower for 1.5se) with Bachmann Controller If the average wind speed exceeds 25 m/s in a 600 s time interval 28 m/s in a 30 s time interval or 30 m/s in a 3 s time interval the wind turbine generator system will shut down. If the average wind speed remains below 22 m/s in a 300 s time interval the wind turbine generator system will cut in again. 1.5s_PCD_allComp_xxxxxxxx.ENxx.10a.doc 9/9
