Conditions for Use at Altitudes greater than
2000 m above Sea Level
This section describes the conditions for using safe Inline I/O modules at altitudes greater
than 2000 m above sea level to a maximum of 4500 m above sea level.
15.1
Conditions
Use of the module at altitudes
greater 2000 m above sea level to a maximum of
4,500 m above sea level
is possible under the following conditions:
1.
Determine the maximum ambient temperature for operation with the corresponding fac-
tor in accordance with the table below.
2.
If derating is specified, offset all the derating points by the corresponding factor in accor-
dance with the table below.
For relay outputs:
3.
Limit the maximum switching voltage for relay outputs in accordance with the table
below. Observe the technical data for the module.
Observe the relevant data (technical data, derating, etc.) that is specific to the module
being used.
