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 surpass requirements to 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
An additional measure could be an installation of the S7-300 in a cabinet or housing.
Mechanical environmental conditions
The table below shows the mechanical environmental conditions in the form of sinusoidal
oscillations.
Frequency band Continuous Infrequently
10 Hz ≤ f ≤ 58 Hz 0.0375 mm amplitude 0.75 mm amplitude
58 Hz ≤ f ≤ 150 Hz 0.5 g constant acceleration 1 g constant acceleration
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.)
