Altitude derating
At altitudes from 1000 to 4000 m (3300 to 13123 ft) above sea level, the derating is 1% for
every 100 m (328 ft). If ambient temperature is below +40 °C (+104 °F), the derating can
be reduced by 1.5% for every 1 °C reduction in temperature. For a more accurate derating,
use the DriveSize PC tool. A few altitude derating curves are shown below.
