3.4.6 – Grounding of the outdoor equipment
Grounding of the outdoor equipment consists of:
– connecting the grounding of the RBS Unit with the pole–mounting grounding
– connecting the coupled RBS unit and pole–mounting grounding to the earthing system.
Considerations
– For grounding the RBS radio unit, a green/yellow cable with insulating sheath must be used. The
minimum cross–section of the conducting wire is 16 mm
2
.
– On the pole–mounting assembly, the ground terminal comprises two tapped holes et the rear of the
metal cast supporting the RBS radio (see Figure 19). According to the installation, choose the most
suitably positioned tapped hole. The grounding screw screws on in one of the two nuts inserted into
the metal cast supporting the RBS. When changing the grounding position block the nut to avoid
to lose it.
Storage
1. Crimp a terminal lug (ref. 16–6 CT) at each end of the cable linking the RBS unit and pole–mounting ground
connections.
