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 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. For derating curve, please see Design Guide

MG18C3YY.

1.8.2

Derating for Low Air Pressure

The cooling capability of air is decreased at low air

pressure. For altitudes above 2000 m, please contact

Danfoss regarding PELV. Below 1000 m altitude no de-

rating is necessary, but above 1000 m the ambient

temperature or the maximum output current should be

decreased. Decrease the output by 1% per 100 m altitude

above 1000 m or reduce the max. ambient temperature by

1° per 200 m.
