Testing for Mechanical Environmental Conditions
The following table provides information on the type and scope of tests for mechanical
environmental conditions.
Condition Test Standard Terminal and Electronic Modules
Vibrations Vibration test in
accordance with
IEC 60068-2-6
Type of vibration: Frequency sweeps with a sweep rate of 1
octave/minute.
5 Hz ≤ f ≤ 8 Hz, constant amplitude of 0.75 mm
8 Hz ≤ f ≤ 150 Hz, constant acceleration of 10 g
Duration of vibration: 10 frequency sweeps per axis in each of the
3 perpendicular axes
Shock Shock, tested in
accordance with
IEC 60068-2-27
Type of shock: half sine
Force of shock: 30 g peak value, 18 ms duration
Direction of shock: 3 shocks each in +/- direction in each of the
3 perpendicular axes
Repetitive shock Shock, tested in
accordance with
IEC 60068-29
Type of shock: half sine
Force of shock: 25 g peak value, 6 ms duration
Direction of shock: 1000 shocks each in +/- direction in each of the three
perpendicular axes
Reduction of Vibrations
If fail-safe modules are subjected to greater shocks or vibrations, you must take appropriate
measures to reduce acceleration and amplitude.
We recommend that you mount the ET 200pro on damping material (e.g., on a rubber-metal
vibration damper).
