Cabling when using cable joint 

 

 

 
Figure 5. Cable joint 

 

Connections of the sensor cable inside the cable joint are explained in 
figure 8. Cable shields and possible excess wires need to be connected 
to the same point in galvanic contact. 

Please  make  sure,  that  the  sensor  and  cable  between  SET-1000 
control  unit  and  the  sensor  do  not  exceed  the  maximum  allowed 
electrical parameters 

– see appendix 1 Technical data. 

IP  rating  of  the  cable  joint  is  IP68.  Make  sure,  that  the  cable  joint  is 
closed properly. 

If  the  sensor  cable  must  be  extended  and  there  is  a  need  for 
equipotential grounding, it should be done with the junction box LJB2. 
The  cabling  between  the  SET-1000  control  unit  and  the  junction  box 
should be done with a shielded twisted pair instrument cable.
