Operating Manual

4. Loosen the screws of the two-part cable 

feed-through.

5. Remove the half without the T-shaped fastening 

pieces.

6. Lay the data cable for communication and the data 

cable for control and measuring signals of sufficient 
length from the cable feed-through with the 
T-shaped mounting tab to the desired connection 
point and secure it with cable ties.

7. Bolt the halves back together. Fasten the screws 

hand-tight.
The data cables and placeholders (plastic stick) 
must be firmly pressed between both sides of the 
two-part cable feed-through. This ensures tightness 
of the enclosure.

8. Position the cable feed-through including the cable 

from the outside in the enclosure.

9. Position the mounting plate of the two-part cable 

feed-through and fasten it hand-tight.

10. Repeat steps 1 to 9 for the remaining data cables. 

Use the second two-part cable feed-through.
