A 3 Use of MSI 100/200 modules at altitudes above
2000 m above sea level
The following chapter describes the conditions for using modules of the MSI 100/200 system
at altitudes above 2000 m above sea level.
Observe the respective, specific data (technical data, derating, etc.) of the used module. 
See "Technical data and ordering data" on page 101.
Use of the module at altitudes above 2000 m above sea level to max. 4500 m above sea
level is possible under the following conditions:
1. Determine the maximum ambient temperature for operation with the corresponding factor
acc. to the following table.
2. If a derating is specified, shift all points of the derating curve by the corresponding factor
according to the following table.
Operation altitude above sea level
2000 m
2500 m
3000 m
3500 m
4000 m
4500 m
3. Limit the maximum switching voltage for relay outputs acc. to the following table. Note the
technical data of the device here.
