4.6.3 Derating the ambient temperature
If the device is installed outside the corresponding specifications, derating the maximum permissible ambient tem-
perature must be taken into account (see
"Ambient conditions" on page 14
). Depending on the display size, der-
ating must be taken into account under the following conditions:
•
Spacing for air circulation is not observed (see
).
•
Permissible mounting orientations are not observed (see
"Mounting orientations" on page 41
The following derating must be taken into account during commissioning:

If one or more of the above conditions apply, the device is permitted to be derated up to the maximum operating
temperature (see ambient conditions in the technical data) minus the specified derating temperatures.
If several conditions apply, the individual derating values must be added together.
