Degree of contamination
The Safety-Integrated safety function:
The components must be protected against conducted contamination (e.g. by installing them in a cabinet with degree of
protection IP54B to EN 60529).
Provided that conducted interference can be prevented at the installation site, the degree of protection for the cabinet can
be decreased accordingly.

The devices may be operated only in environments with degree of
pollution 2 and without condensation. On control cabinets with forced air
cooling, foreign particles must be filtered out of the inflow air through filter
mats.
To prevent condensation, the devices can be warmed constantly by
heaters.
