DANGER

 

Loss of explosion protection! 

Danger of explosion in hazardous areas by open or not properly closed device!

 

 

 
Before  closing  the  door  of  the  EX-d  box,  the  intactness  and  cleanness  of  the 
machined flange surfaces and the gasket is to check in any case.

Before closing the lid of the PLC- box (EX-p box) the intactness and cleanness of 
the gasket is to check in any case. 

6.3.8  Electrical connection  

 

 

 

DANGER

 

Danger from electrical shock! 

Only a trained electrician may modify the electrical equipment of the combustion 
calorimeter in accordance with the relevant guidelines! 

When the combustion calorimeter has been opened, the parts identified by the 
adjacent symbol may still be live even when the master switch has been turned 
off. If necessary, disconnect combustion calorimeter from the voltage mains! 

 
Further information: 

 enclosed documentation! 

– Wiring diagram - 

 
The  connections for the power  supply  are  located  at the  inside  of the  PLC  -box 
(EX-P box).
