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 damage or injury, 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.

Field Mounting

"
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units (planned) are recommended.
