2.2 Installation of the Hybrid IP-PBX

2.2.14 Surge Protector Installation

Overview

A massive electrical surge can be caused if lightning strikes a telephone cable 10 m above ground, or if a telephone line comes into contact with a power line. A surge protector is a device that is connected to a trunk to prevent potentially dangerous electrical surges from entering the building via the trunk and damaging the Hybrid IP-PBX and connected equipment.

To protect the system from electrical surges, we strongly recommend connecting the system to a surge protector that meets the following specifications:

–Surge arrestor type: 3-electrode arrestor

–DC spark-over voltage: 230 V

–Maximum peak current: at least 10 kA

Additionally, proper earthing is very important for the protection of the system (refer to "2.2.5 Frame Earth Connection").

Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable laws, regulations, and guidelines.
