3.1 Mounting information
Mechanical and climatic conditions of use
The HMI device is intended for installation in weatherproof permanent locations. 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
Examples of applications where the use of the HMI device requires additional measures:
● In locations with a high degree of ionizing radiation
● In locations with extreme operating conditions resulting from situations as follows:
– Corrosive vapors, gases, oils or chemicals
– Electrical or magnetic fields of high intensity
● In plants requiring special monitoring features, for example:
– Elevator systems
– Systems in especially hazardous rooms
