5. Screw the the cable glands (Fig. 20, item 6) with the counternut cable glands
(Fig. 20, item 7).
Apply the voltage of the specified and marked (Fig. 20, item 3) range only!
Note the specification relating to Cables, Protective earth, equipotential bond-
ing and EIA-485 (RS-485) in chapter 5.1.
6. Connect the lines according to assignment (chap.5.4 or chap.5.5) to the ter-
minal board (Fig. 20, item 3).
7. Open the terminal connection (Fig. 20, item 4) with an operating tool (slot-
ted screwdriver) and insert the stripped wire (min. 8 mm) (Fig. 20,item 5). The
terminal connection closes by pulling out the operating tool.
The terminal connections are designed for wires (flexible) with a conductor
cross-section from 0.2 mm² to 2.5 mm² (with ferrule without plastic sleeve) or
0.2 mm² to 1.5 mm² (with ferrule with plastic sleeve). AWG = 24 – 12.
8. Plug the network plug into the RJ45 socket (Fig. 20, item 9) (optional).
9. Tighten all cable glands (Fig. 20, item 6) to ensure optimal sealing and ten-
sion relief until the gasket insert closes between screw down nut and cable.
10. Check tension relief of all cable glands by pulling the cables smoothly.
The cables must not move. If necessary tighten the cap nuts of the cable
glands.
11. Slide the subrack into the wall housing and lock it with the square wrench.
The wall enclosure is supplied with blanking elements in all cable glands. It
must be ensured that there are blanking elements in all unused cable glands.
Otherwise, the IP protection is not given.
Only use cable that is suitable for connection to the corresponding terminals
may be used. Detailed specifications can be found in the chapter 5.1.2 Cables
and Lines.
The master/slave connections of the installed devices are already manufac-
tured above the circuit board in the wall housing. If additional slave modules
(e.g. from other wall housings) are connected, the terminals appropriate for
use on the terminal board should be used.
