■ Mechanical installation
Please pay attention to the requirements
that apply to integration and field mounting
kit, see the below list. The information given
in the list must be observed to avoid serious damage
or injury, especially when installing large units.
The VLT AFD must be installed vertically.
The VLT AFD is cooled by means of air circulation.
For the unit to be able to release its cooling air, the
minimum distance over and below the unit must
be as shown in the illustration below.
To protect the unit from overheating, it must be ensured
that the ambient temperature does not rise above the
max. temperature stated for the VLT AFD and that
the 24-hour average temperature is not exceeded.
The max. temperature and 24-hour average can be
seen from the General Technical Data.
If the ambient temperature is in the range of 45°C
-55° C, derating of the VLT AFD will become relevant,
see Derating for ambient temperature.
The service life of the VLT AFD will be reduced if derating
for ambient temperature is not taken into account.
