  Insert end of cable into stripping tool 

and fix it tightly until stopped 

 

 
 
 
 

 

 

 
 

The switchable terminating resistors are 
activated by a slide switch accessible from 
both the side and rear.  With this switch, 
the OUT Bus can be shut off. For testing 
purposes the PROFIBUS components 
following the connector can be switched off 
without removing the plug.
