2.7 Grounding cable installation
Figure 9 Grounding wire installation
The gateway is considered a permanently connected device and requires a permanently connected
protective earth (PEG) conductor. The ground connection of the protective earth is through a grounding
hole of an M6 on the shell, as shown in the figure above.
The gateway grounding system should follow local and national electrical codes. The protective
earth conductor of the grounding hole is mandatory. It must be the first one to be connected at the time
of grounding. The proper wiring and connection of this cable is the key to strong lightning resistance.
Connection inductance and ground resistance should be minimized.
The grounding cable installation steps are as follows:
1. Gently grind the surface of the antenna feeder lightning arrester with a fine steel wire brush to
remove the oxide layer.
2. Use a clean cloth to remove debris from the surface.
