The frequency converter is cooled by means of air circulation.
To protect the unit from overheating, it must be ensured that the ambient temperature does not exceed
the maximum temperature stated for the frequency converter and that the 24-hour average temperature
is not exceeded. Locate the maximum temperature and 24-hour average in the paragraph Derating for
Ambient Temperature.
If the ambient temperature is in the range of 45 °C - 55 ° C, derating of the frequency converter will
become relevant, see Derating for Ambient Temperature.
The service life of the frequency converter is reduced if derating for ambient temperature is not taken
into account.
Field Mounting
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.
