2.2 Installation of the Hybrid IP-PBX 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.
