Planning application
3.1 Application and ambient conditions
● In systems that require special monitoring, for example:
Testing for mechanical environmental conditions in accordance with GS-ET-22
The following table provides information on the type and scope of tests for mechanical
ambient conditions.
The table applies to the HMI device, charging station and transponder.
Tested for
Vibrations
Shock
Continuous shocks IEC 60068, Part 2–29
Impact
The table only applies to the HMI device, with and without battery.
Tested for
Falling
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).
