Installation – 51
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.
6.4.2 Requirements to the lightning protection unitAUX-ODU-LPU-Llocation
AUX-ODU-LPU-L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-Lshould be properly
assembled, mounted and grounded.
General recommendations for installations of lightning protection units:
Install the lightning protection unit on both ends of the cable to protect both the outdoor and the indoor
unit.The purpose of theLPUat the top is to protect theODUfrom a surge of lightning strike which can hit
the long FTP cablerun along the height of the pole or on the roof of the building.The purpose of theLPUat
the bottom is to protect theIDUand customer equipment.
Use the lightning protection unit to protect all circuits for signal transmission and power supply (video,
audio, management signals, Ethernet, etc.)
Regularly (especially before the periods with high thunderstorm activity) check the integrity of lightning
protection units, grounding elements andbonding conductors.
The ports of the AUX-ODU-LPU-L device are symmetrical, i.e. the correspondence of ports position to the
external unit and the power supply does not matter.
Make sure to install the twoLPUdevices as shown in the scheme below.

CAUTION
Please note grounding cables should not be connected to the mast. All devices must use separate
grounding cable that should be connected to the grounding circuit. The best scenario is when grounding
cables are lined parallel to the Ethernet cable.
