" Safety Requirements of Mechanical Installation
Pay attention to the requirements that apply to inte gration and the field mounting kit. Follow the
information in the list to avoid serious damage or injur y, e spe cially wh en installing large units.
The adjustable frequency drive is cooled by air circulation.
To protect the unit from overheating, it must be ensured that the ambient temperature does
not e xceed the maximum temperature stated for the adjustable frequency drive and that the
24-hour average temperature is not e xceeded. Locate the maximum temperature and 24-hour
average in the paragraph Derating for Ambient Temperature.
If the ambient temperature is in the range of 113° - 131°F [45°C - 55°C], derating of the adjustable
frequency drive will become relevant, see Derating for Ambient Temperature.
The service life of the adjustable frequency drive is reduced if derating for ambient
temperature is not taken into account.
" Field Mounting
