Installation Manual 39
2.2.5 Frame Earth Connection
IMPORTANT
Connect the frame of the Hybrid IP-PBX to earth.
• Be sure to comply with applicable local regulations (e.g., law, guidelines).
• Proper earthing (connection to earth) is very important to protect the Hybrid IP-PBX from
the bad effects of external noise or to reduce the risk to the user of electrocution in the
case of lightning strike.
• The earthing wire of the AC cable has an effect against the external noise and lightning
strikes, but it may not be enough to protect the Hybrid IP-PBX. A permanent connection
between earth and the earth terminal of the Hybrid IP-PBX must be made.
