This section describes factors to be considered when planning the proposed link end sites, including grounding, lightning protection and equipment location for the wireless device, power supply and , AUX-ODU-LPU-L and AUX-ODU-LPU-G unit (if installed).

...

• The wireless device should be placed on the pole at a height that is at least 1 meter below the top of the pole. In this case, there is a significant probability that the lightning strikes the pole and not the wireless device. The pole should be properly grounded: connected to the building lightning protection circuit according to your local regulations.
•  All equipment must be connected at stabilized and surge protected power sources which must be properly grounded.
• The end of the FTP service cable that is connected to the power supply should be assembled with a shielded RJ-45 connector. The other end of the FTP service cable (connected to the wireless device) should be assembled with unshielded (standard) RJ-45 connector.
• The power supply is grounded via a three-conductor power cord and a grounded socket.
• AUX-ODU-LPU-L, AUX-ODU-LPU-G and wireless device grounding is performed using grounding bolt.
• Antenna pole and wireless device should be connected to the common ground ring. Grounding cables should be no less than 10AWG thick and must use corrosion-resistant connectors.
