1.8 Special Conditions
1.8.1 Derating for Ambient Temperature
The ambient temperature measured over 24 hours should be
at least 5
°
C lower than the max. ambient temperature. If the
frequency converter is operated at high ambient
temperature, the continuous output current should be
decreased.
1.8.2 Derating for Low Air Pressure
The cooling capability of air is decreased at low air pressure.
For altitudes above 2000m, please contact Danfoss regarding
PELV. Below 1000m altitude no de-rating is necessary, but
above 1000m the ambient temperature or the maximum
output current should be decreased. Decrease the output by
1% per 100m altitude above 1000m or reduce the max.
ambient temperature by 1 degree per 200m.
