WARNING
• Proper connection to earth is very important to reduce the risk to the user of electrocution or to protect the PBX from the effects of
external noise or lightning strike.
• The earth wire of the AC cable has an effect against external noise and lightning strikes, but it may not be enough to protect the PBX
and to ensure electromagnetic compatibility. A permanent connection between earth and the earth terminal of the PBX must be
made.
• To protect the system from electrical surges, it is strongly recommend to connect 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
Many countries/areas have regulations requiring surge protection.
Be sure to comply with all applicable laws, regulations, and guidelines.
