6.4.1 Grounding and lightning protection
recommendations
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-G 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.
Special attention should be paid if the external antenna used is not DC-shorted. In this
case, an additional lightning arrestor should be used between the antenna and ODU.
6.4.2 Requirements to the lightning protection unit location
AUX-ODU-LPU-G is an optional accessory which may be used to serve as a line protection unit
for the ODU and for the indoor network equipment connected to the Ethernet port of the IDU.
AUX-ODU-LPU-G should be properly assembled, mounted and grounded.
General recommendations for installations of lightning protection units:
