Mechanical and climatic ambient conditions
Operating conditions
The S7-1500R/H redundant system is 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)
Test of mechanical ambient conditions

Reduction of vibrations
If the S7-1500R/H redundant system is exposed to severe shock or vibration, take
appropriate measures to reduce the acceleration or the amplitude.
We recommend installing the S7-1500R/H redundant system on damping materials (for
example, rubber-bonded metal mounting).
