Basic safety information 

 

 

Note 
Material compatibility 
Siemens can provide you with support concerning selection of sensor components wetted by 

process media. However, you are responsible for the selection of components. Siemens 

accepts no liability for faults or failures resulting from incompatible materials. 

 

 

 

WARNING 

Unsuitable connecting parts 
Danger of injury or poisoning.  
In case of improper mounting hot, toxic and corrosive process media could be released at 

the connections. 

•

 

Ensure that connecting parts (such as flange gaskets and bolts) are suitable for 

connection and process media. 

 
 

 

WARNING 

Exceeded maximum ambient or process media temperature 
Danger of explosion in hazardous areas. 
Device damage. 

•

 

Make sure that the maximum permissible ambient and process media temperatures of 

the device are not exceeded. 

 
 

 

WARNING 

Open cable inlet or incorrect cable gland 
Danger of explosion in hazardous areas. 

•

 

Close the cable inlets for the electrical connections. Only use cable glands or plugs 

which are approved for the relevant type of protection.
