Combined Assembly - Single and Triple Modules 

A combined wall assembly of single and triple modules allows you to create 
units consisting of 2, 4 and 5 units. This procedure consists of the following 
steps: 

1.  Drill the necessary holes in the wall (2 plastic dowels for each module), so 

that the lower plate will cover the hole through which the cables pass. 

2.  Insert the cables in the cable clamp without pulling out the screws. 
3.  Link the frames together by inserting the two enclosed attachment clips at 

the rear of the frames (see Figure 6 and Figure 7). 

4.  Use the dowels to fasten the frame to the wall. Make sure that the lamellar 

connector is in the UP position. 

5. Adjust the length of the cables so that they protrude by ~10cm from the 

wall, and fasten them to the cable crimp. 

6. Intertwine the terminators of the cables from the wall and the extension 

cable terminators, and fasten them to the cable crimps. 

7. Fasten the cable crimp to the contacts in the direction shown in Figure 6 

and Figure 7. 

8. Place the remainder of the cable inside the frame and lock the cable 

clamp.
