Climatic ambient conditions
The following table shows the permissible climatic ambient conditions for the ET 200SP HA
distributed I/O system.
Table 9-12 Climatic ambient conditions
Ambient conditions Permissible range Comments
Temperature
● Horizontal installation: from
-40°C to 70°C
● Vertical installation: from -40°C
to 60°C
Note: No icing
Observe any load-dependent limitations.
Refer to the documentation of the employed component.
Tested according to IEC 60068-2-2 (Dry heat)
Air pressure
● From 1 080 hPa
(corresponds to a depth of
approximately -1 000 m)
● Up to 606 hPa
(corresponds to an elevation of
approximately 4 000 m)
The density of the air decreases with increasing altitude. The
cooling effect of air in accordance with the elevation is shown in
the following table on derating.
Relative humidity From 10 to 95%
Max. 95% at +25 °C
Without condensation, corresponds to relative humidity (RH)
stress grade 2 in accordance with IEC 61131 part 2
Tested according to IEC 60068-2-78 (Damp heat)

Derating
The cooling effect of air decreases at higher altitudes as a result of its lower density.
The table shows the derating factor for the maximum permissible ambient temperature
depending on the use of the devices at an elevation above sea level.
Table 9-13 Derating when devices are used at an elevation above sea level
