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:
– Corrosive vapors, gases, oils or chemicals
– Electrical or magnetic fields of high intensity
● In systems that require special monitoring, for example:
– Elevators
– Systems in especially hazardous rooms
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.
