Installation and Operating Manual, 08/2008, A5E00103686-07
Mechanical Environmental Conditions
The table below shows the mechanical environmental conditions for F-modules in the form of
sinusoidal oscillations.
Frequency Range (Hz)
Continuous
Intermittent
10 ≤ f ≤ 58
Amplitude = 0.15 mm
Amplitude = 0.35 mm
58 ≤ f ≤ 150
Constant acceleration = 2 g
Constant acceleration = 5 g
Reduction of Vibration
If the F-modules are exposed to substantial shock or vibration, you must take appropriate
measures to reduce the acceleration and amplitude.
We recommend that you mount the ET 200S on damping material (for example, on a rubber-
metal vibration damper).
Testing of Mechanical Environmental Conditions
