2.2.10 Surge Protector Installation
Overview
A massive electrical surge can be caused if lightning strikes a telephone cable 10 m (33 ft) 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 CO line to prevent potentially dangerous electrical surges from entering the building via the CO line 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 grounding is very impor tant for the protection of the system (refer to 2.2.5 Frame 
Ground Connection).
Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable 
laws, regulations, and guidelines.
