5.1.4 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
frequency converter is not exceeded
and that the 24-hour average temperature
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
Temperature
.
The service life of the frequency converter is reduced if derating for ambient temperature is not taken into account.
5.1.5 Field Mounting
For field mounting the IP 21/IP 4X top/TYPE 1 kits or IP 54/55 units are recommended.
