Using the ET 200SP distributed I/O system over 2000 m above sea level
The maximum "operating height above sea level" depends on the module and is described in
the technical specifications of the respective module. The product data sheets with daily
updated technical specifications can be found on the Internet
(https://support.industry.siemens.com/cs/ww/en/ps/td) at Industry Online Support. Enter the
article number or the short description of the desired module on the website.
For altitudes > 2000 m, the following constraints apply to the maximum specified ambient
temperature:
Restrictions of the specified maximum ambient temperature in reference to the
installation altitude
Installation altitude
-1000 m to 2000 m
2000 m to 3000 m
3000 m to 4000 m
4000 m to 5000 m
Base value for application of the derating factor is the maximum permissible ambient temperature in °C for 2000 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.
• Note the mounting position of the respective module in the technical specifications. The
basis is the standard IEC 61131-2:2017.
• Make sure that the power supplies you use are rated for altitudes > 2000 m.
