1.8 Special Conditions

1.8.1 Derating for Ambient Temperature and Switching Frequency

The ambient temperature measured over 24 hours should be at least 9 °F [5 °C] lower than the max. ambient temperature.
If the adjustable frequency drive is operated at a high ambient temperature, the continuous output current should be
decreased. For derating curve, see VLT

1.8.2 Derating for Low Air Pressure

The cooling capability of air is decreased at low air pressure. For altitudes above 6,600 feet [2 km], contact Danfoss
regarding PELV. Below 3,300 ft [1,000 m] altitude, no de-rating is necessary, but above 3,281 ft [1,000 m], the ambient
temperature or the maximum output current should be decreased. Decrease the output by 1% per 330 ft [100 m] altitude
above 3,300 ft [1,000 m] or reduce the max. ambient temperature by 1° per 660 ft [200 m].
