All inputs, outputs, circuits, DC supplies and relay contacts are galvanically isolated from the supply voltage (PELV) and
other high-voltage terminals.

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.
