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

HVAC Basic Design Guide
.
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].
