2.4 Grounding and Lightning Protection
You should protect the gNB, antenna, and GPS against lightning. Following are guidelines concerning
grounding.
•
The yellow-green ground wire must be at least
6 AWG (10 mm²) in
diameter.
•
Always place the grounding as near as possible to the equipment.
•
Connect to a reliable outdoor grounding point (earth) using one ground screw.
•
The connection between the grounding points and the grounding bar must be tight and reliable.
Rustproofing the terminals, e.g., with antioxidant coating or grease, is required.
