    1.8.2 Derating for Low Air Pressure The cooling capability of air is decreased at low air pressure. For altitudes above 2000 m, contact Danfoss regarding PELV. Below 1000 m altitude no derating is necessary, but above 1000 m the ambient temperature or the maximum output current should be decreased.
