Restrictions on the maximum specified ambient air temperature with reference to the installation altitude
Installation altitude
-1 000 to 2 000 m
2 000 to 3 000 m
3 000 to 4 000 m
4 000 to 5 000 m
The basic value for the application of the derating factor is the maximum permissible ambient temperature in °C for
1)
2 000 m
Note
• Linear interpolation between altitudes is permissible.
• The derating factors compensate for the decreasing cooling effect of air at higher altitudes due to lower density.
• Pay attention to the mounting position of the respective module in the technical data. Based on the IEC 61131-2:2017
standard.
• Ensure that the power supply units used are also adequate for altitudes > 2 000 m.
• The displays of the S7-1500 CPUs are designed for an altitude of ≤ 3 000 m. If used at > 3 000 m, in rare cases, there can
be problems in the representation of the CPU display; however, these do not have an effect on the functional safety of the
F-CPU.
• The "Safety-oriented tripping of standard modules" function, as described on the SIEMENS Industry Online Support
(https://support.industry.siemens.com/cs/ww/en/view/39198632) pages, is only approved up to max. 2 000 m.
Effects on the availability
The higher cosmic radiation present during operation at altitudes above 2 000 m will also start to have an effect on the
failure rate of electronic components (the so-called soft error rate). In rare cases, this can result in a transition of the F-CPU
into the safe state. However, the functional safety of the F-CPU is fully retained.
