5.1.1 Safety Requirements of Mechanical Installation
Pay attention to the requirements that apply to integration and field mounting kit. Observe the information in the list to avoid serious injury or
equipment damage, especially when installing large units.
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.
