6.4 Shipping and Storage Conditions
Requirements for Fail-Safe Modules
Fail-safe modules surpass the requirements for transport and storage conditions defined in
IEC 61131, Part 2. The following specifications apply for fail-safe modules that are
transported and stored in the original packaging.
Type of Condition Permissible Range
Free fall ≤ 1 m
Temperature From –40 °C to +70 °C
Temperature variation 20 K/h
Air pressure 1080 hPa to 660 hPa
(corresponds to an altitude of -1000 m to 3500 m)
Relative humidity 5% to 95%, no condensation
6.5 Mechanical and Climatic Environmental Conditions
Conditions of Use
The F-modules are intended for use as stationary installations in sheltered locations. The
conditions of use surpass the requirements in accordance with IEC 61131-2.
Fail-safe modules comply with conditions of use Class 3C3 in accordance with DIN EN
60721 3-3 (use in locations with heavy traffic and in the immediate vicinity of industrial
systems with chemical emissions).
Restrictions
F-modules cannot be implemented without additional measures being taken:
● In locations with a high level of ionizing radiation
● In locations with severe operating conditions, due for example to:
– Dust
– Corrosive vapors or gases
● In systems which require special monitoring, such as:
– Electrical systems in particularly hazardous areas
An additional measure for the implementation of fail-safe modules can be installing the
ET 200S in cabinets, for example.
