- 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.
Make sure to install the two LPU devices in the correct polarity, two LPU devices as shown in the diagram:
- Top LPU with "ETH OUT" facing the ODU.
- Bottom LPU with "ETH OUT" facing the IDU.
- LPU units connected to each other via "ETH IN".
