2.2.11 Lightning Protector Installation

Overview

A lightning protector is a device to be installed on a trunk to prevent a dangerous surge from entering the building and damaging equipment.

A dangerous surge can occur if a telephone line comes in contact with a power line. Trouble due to lightning surges has been showing a steady increase with the development of electronic equipment.

In many countries/areas, there are regulations requiring the installation of lightning protection. A lightning strike to a telephone cable which is 10 m above ground can be as high as 200 000 V.

The Hybrid IP-PBX should be installed with lightning protectors. In addition, earthing (connection to earth) is very important for the protection of the Hybrid IP-PBX.

Be sure to comply with applicable local regulations (e.g., law, guidelines).
