16.4 Mechanical and climatic ambient conditions
Operating conditions
The S7-1500 automation system is suitable for use in weather-proof, fixed locations. The
operating conditions exceed requirements according to DIN IEC 60721-3-3:
● Class 3M3 (mechanical requirements)
● Class 3K3 (climatic requirements)
Test of mechanical ambient conditions
The table below provides important information with respect to the type and scope of the test
of ambient mechanical conditions.

Shock
Continuous shock
Reduction of vibrations
If your S7-1500 automation system is exposed to severe shock or vibration, take appropriate
measures to reduce the acceleration or the amplitude.
We recommend the installation of the S7-1500 automation system on damping materials (for
example, rubber-bonded-to-metal mounting).
