Ambient and Environmental Conditions 

 

 

CAUTION: Damage 

 Do not operate the product beyond the specified ambient conditions 

 

 

DANGER: Explosive Risk 

 Do not operate the product in potentially explosive atmosphere. 

 

 

NOTICE: EMI 

 This product is a class A device. This product may cause radio interference. In this case 
the user must take adequate measures. 

 

 

NOTICE: System overheating 

 The cooling concept of the  emVIEW-7/RPI3  is not sufficient to  allow full loading of the 
Raspberry  PI  3  Module  processor  without  system  overheating  which  leads  to  clock 
reduction. Refer to the technical data for details.
