Applies to the HMI device with and without
battery:
Reducing vibrations
If the HMI device is subjected to greater shocks or vibrations, you must take appropriate
measures to reduce acceleration or amplitudes.
We recommend fitting the charging station of the HMI device to vibration-absorbent material
(on metal shock absorbers, for example).
