NOTE
The end of the FTP service cable that is connected to IDU should be assembled with a shielded RJ-45 connector. The other end of the FTP service cable (connected to ODU) should be assembled with unshielded RJ-45 connector.
IDU is grounded via a three-conductor power cord and a grounded socket. The data & power wires pickups are terminated via IDU protection scheme (three-conductor power cord and a grounded socket).
NOTE
Antenna pole, tower, ODU and lightning arrestor should be connected to the common ground ring. Grounding cables should be no less than 10AWG thick and must use corrosion-resistant connectors. At the end of the FTP cable that connects to the IDU should be used an RJ-45 connector with grounding. At the other end of the cable (connected to the ODU) should be used an RJ-45 connector without grounding.
Special attention should be paid if the antenna used is not DC-shorted. In this case, an additional lightning arrestor should be used between the antenna and ODU.
Grounding diagram is shown in the picture below.
