Ambient mechanical conditions
The ambient mechanical conditions for S7-300 modules are listed in the following
table in the form of sinusoidal oscillations.
Table 1-5 Mechanical Conditions
Frequency Range

Continuous Occasional
10 v f v 58 0.0375 mm amplitude 0.075 mm amplitude
58 v f v 150 0.5 g constant acceleration 1 g constant acceleration
Reducing vibrations
If your S7-300 modules are exposed to severe shock and/or vibrations, you must
take the appropriate measures to reduce the acceleration and/or amplitude,
respectively.
We recommend that you install the S7-300 on vibration-damping materials
(for example, rubber-metal antivibration mountings).
