3.2.14 Surge Protector Installation
CAUTION
Performing surge protection is essential. Make sure to follow the instructions in this section.
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
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 "3.2.5 Frame Earth
Connection").
Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable laws,
regulations, and guidelines.
