Base value for the application of the derating factor is the maximum permissible ambient tempera-
ture in °C for 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.
•
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 also rated for altitudes > 2 000 m.
•
The "Safety-related shutdown of standard modules" function, as described in the Internet
(
https://support.industry.siemens.com/cs/ww/en/view/39198632), is only approved up to
a maximum of 2 000 m.
