6.4 Grounding and Lightning Protection
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,AUX-ODU-LPU-Land AUX-ODU-
LPU-G unit (if installed).
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.
CAUTION
Please note that the pressure equalization system in Infinet devices is performed via gas exchange through
a cable gland and Ethernet cable jacket with a dry room where the power supply is installed. In order to
avoid ODU failure due to moisture entering the device, for example, during the pressure drop during the
rain, the cable gland assembly requirements should be met and there are should be no cracks in the
Ethernet cable jacket.
In addition, you should avoid the Ethernet cable bending near the ODU and pinching with clamps, that can
bring to the pressure equalization system fault between the internal volume of the sealed ODU and the
external environment during a sudden air temperature change. This may lead to the leakage and device
failures.
CAUTION
Electro-magnetic discharge (lightning) damage is not covered under warranty. The recommendations in
this document, when followed correctly, give the user the best protection from the harmful effects of EMD.
However 100% protection is neither implied nor possible.
