1.4 Mechanical And Climatic Environmental Conditions For S7-300 Operation - Siemens SIMATIC Manual

1.4 Mechanical and climatic environmental conditions for S7-300
operation
Operating conditions
S7-300 systems are designed for stationary use in weather-proof locations. The operating
conditions are based on the requirements of DIN IEC 60721-3-3:
● Class 3M3 (mechanical requirements)
● Class 3K3 (climatic requirements)
Use with additional measures
The S7-300 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
Mechanical environmental conditions
The table below shows the mechanical environmental conditions in the form of sinusoidal
oscillations.
Frequency band
10 Hz ≤ f ≤ 58 Hz
58 Hz ≤ f ≤ 150 Hz
Reducing vibrations
If your S7-300 modules are exposed to severe shock or vibration, take appropriate measures
to reduce acceleration or the amplitude.
We recommend the installation of the S7-300 on damping materials (for example, rubber-
bonded-to-metal mounting.)
