Conditions of use
Fail-safe modules are intended for use as permanently installed modules protected from the
elements. The conditions of use exceed the requirements of IEC 61131-2.
Fail-safe modules comply with the conditions of use of 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
Fail-safe modules cannot be implemented in the following locations without additional
measures being taken:
• Locations with a high level of ionizing radiation
• Locations with severe operating conditions; for example, due to
• Systems that require special monitoring, such as:
An additional measure for implementing fail-safe modules can be, for example, installing the
ET 200S in cabinets.
Mechanical Environmental Conditions
The mechanical environmental conditions for fail-safe modules are presented in the following
table as sinusoidal oscillations.
Frequency Range (Hz)
10 ≤ f ≤ 58
58 ≤ f ≤ 150
Reduction of Vibration
If fail-safe modules are subjected to sizable shock pulses or oscillation, you must take
appropriate measures to reduce acceleration and amplitude.
We recommend that you mount the ET 200S on cushioning material (for example, on a
rubber-metal vibration damper).
