Operation with additional protective measures
You must take additional measures to operate the HMI device at the following locations:
● At locations with a high degree of ionizing radiation
● At locations with harsher 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
Attenuating shock and vibration
If the device is subject to severe shock or vibration, you must take appropriate measures to
reduce the amplitude and/or acceleration. In such situations, use vibration damping or
vibration absorber systems.
