4.5.3 Installing PGND Cable
1. Cut a proper length of cable to make a RRU PGND cable according to the actual routing path, and
install an OT terminal at each end of the cable.
The metal wire cannot be exposed when the PGND cable is prepared on the field, as shown below.
2. Connect the OT terminal of the RRU PGND cable to the grounding port at the RRU bottom, and the
OT terminal at the other end to the external grounding bar.
3. Stick a label to the installed cables.
