1.4 Mechanical and ambient conditions for S7-400 operation
Operating conditions
S7-400 systems are designed for stationary use in weather-proof locations. The S7-400 fulfills
the requirements for use in accordance with IEC 60721-3-3:
● Class 3M3 (mechanical requirements)
● Class 3K3 (climatic ambient conditions)
Use with additional measures
The S7-400 may not be used under the conditions outlined below without taking additional
measures:
● at locations with a high degree of ionizing radiation
● in aggressive environments caused, for example, by
– the development of dust
– corrosive vapors or gases
– strong electric or magnetic fields
● in installations requiring special monitoring, for example
– elevators
– electrical plants in potentially hazardous areas
An additional measure would be to install the S7-400 in a cabinet or housing.
Mechanical ambient conditions
The mechanical ambient conditions for S7-400 modules are listed in the following table in the
form of sinusoidal vibrations.
Table 1-6 Mechanical ambient conditions
Frequency range in Hz Test values
10 ≤ f < 58 0.075 mm amplitude
58 ≤ f < 500 1 g constant acceleration
Reducing vibrations
If your S7-400 modules are exposed to severe shock or vibration, take appropriate measures
to reduce acceleration or the amplitude.
We recommend the installation of the S7-400 on damping materials (for example, rubber-metal
vibration dampers.)
