8.4.5.2 Conditions of use
Mechanical and climatic conditions of use
The HMI device is designed for use in a location protected from the effects of the weather.
The conditions of use are compliant with requirements to DIN IEC 60721-3-3:
●
Class 3M3 (mechanical requirements)
● Class 3K3 (climatic requirements)
Use with additional measures
The HMI device should not be used at the following locations unless additional measures are
taken:
●
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 plants that require special monitoring - for example:
–
Elevators
– Systems in especially hazardous rooms
Mechanical ambient conditions
The mechanical ambient conditions for the HMI device are specified in the following table in
terms of sinusoidal vibration.
Frequency range in Hz Constant Occasional
10 ≤ f ≤ 58 Amplitude 0.0375 mm Amplitude 0.075 mm
58 ≤ f ≤ 150 Constant acceleration 0.5 g Constant acceleration 1 g
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 HMI device to vibration-absorbent material (on metal shock
absorbers, for example).
