Use with additional protective measures
You may only use the HMI device at the following locations with additional protective
measures:
● In locations with a high degree of ionizing radiation
● In locations with difficult operating conditions, for example due to:
● In systems that require special monitoring, for example:
Damping shock and vibration
If the HMI device is subjected to strong shocks or vibrations - as specified in the following
table - you must take appropriate measures to reduce amplitudes or acceleration. In such
situations, use vibration damping or vibration absorber systems for the HMI device and
accessories.
Testing mechanical ambient conditions
In the following table contains tests that were checked on the HMI device in regards to the
ambient conditions for operation.
