4.4 Connecting Cable 
The APM 3DLinkPro po er supply is connected  ith standard cable 
according to national installation standards. An outer cable 
diameter of 5…9 mm ensures the seal effect of the cable entry. If 
electromagnetic interference is expected,  e recommend the use of 
screened cable for the signal lines. 
 
Proceed as follo s to connect cable to the po er supply: 
1. Loosen the four scre s of the housing  ith a scre  driver 
2. Remove the housing cover 
3. Unscre  the po er supply lines from the left green connector 
of the 3DLevelScnner 
4. Remove the cable from the 3DLeveScanner through the gland 
5. Insert the cable through the left gland of the 3DLinkPro 
6. Open the terminals  ith a scre driver 
7. Connect the  ires to sockets "1" and "2" according to the 
diagram. Take note of the polarity. 
8. Close the terminals 
9. Tighten the compression nut of the cable entry. The seal ring 
must completely encircle the cable 
10. Scre  the housing cover back on 
11. If the cable is screened please follo  the procedure in the 
"cable screening and grounding" paragraph 
12. Tighten the compression nut of the cable entry. The seal ring 
must completely encircle the cable 
 
The electrical connection is finished. 
 
4.5 Connecting the Communication 
(4…20mA/HART) to the APM 3DLinkPro 
1. Unscre  the communication lines (2W of 4…20mA/HART) from 
the left green connector of the 3DLevelScnner. 
2. Remove the cable from the 3DLeveScanner through the gland 
3. Insert the cable through the left gland of the APM 3DLinkPro 
4. Connect the  ires to sockets "3" and "4" according to the 
 iring diagram, above. 
4.6 Connecting the RS-485 wires to the APM 
3DLinkPro 
Connect t o  ires to sockets "11" and "12" according to the 
diagram belo .
