Siemens Simatic S7-1500H - Mechanical and Climatic Ambient Conditions

15.4 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 IEC61131-2:2017:
•
OTH4
•
STH4 (R/H CPUs: Minimum ambient temperature -40°C, minimum relative humidity 5%)
•
TTH4 (R/H CPUs: minimum relative humidity 5%)

Direction of shock: 1000 shocks each in (+/-) direction, along each of the 3
mutually perpendicular axes
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).
