4.4.4 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. Depending on the display size, derating must be taken into account under
the following conditions:
•
Spacing for air circulation is not observed (see
"Spacing for air circulation" on page 28
).
•
Specified mounting orientation with limitation (see
"Mounting orientations" on page 29
•
Wall thickness of the installation cutout > 4 mm (see
"Installation cutout" on page 47
If one or more of the above conditions apply, the device is permitted to be derated up to the maximum operating
temperature
3)
minus the total derating.
If more than one applicable derating condition exists, the total derating must be calculated as follows:
1) For combined mounting orientations (horizontal and vertical inclination), use the higher derating; see cal-
culation example A.
2) For a mounting orientation with limitation, 100% display brightness (15.6" variant only) and wall thickness
>4 mm, the derating values must be added; for combined mounting orientations (horizontal and vertical
inclination), proceed as described above in point 1); see calculation example B or C.
3) In the event of a mounting orientation with limitation, wall thickness >4 mm and undershooting of the spacing
for air circulation, the temperatures during operation must be monitored continuously in addition to the
derating values from item 1) or 2).
Caution!
The specified spacing for air circulation applies at the maximum specified ambient temperature. The
maximum specified ambient temperature is not permitted to be exceeded!
If the specified spacing for air circulation cannot be maintained, the maximum specified temperatures
of the temperature sensors (see
"Temperature sensor positions" on page 32
) must be monitored in the
application and appropriate measures taken if these values are exceeded.
