Surge Protector Installation - Panasonic KX-TDA600 - Hybrid IP PBX Control Unit Max. 1008 Ports Installation Manual

2.2.16 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 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 grounding is very important for the protection of the system (refer to "2.2.10 Frame
Ground Connection").
Many countries/areas have regulations requiring surge protection. Be sure to comply with all applicable
laws, regulations, and guidelines.
