2.6 Connecting Extensions
2.7 Frame Earth Connection
IMPORTANT!
Connect the frame of the Hybrid IP-PBX to earth.
• 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 strikes.
• The earth 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.
1. Loosen the screw.
2. Insert an earthing wire (user-
supplied)*.
3. Tighten the screw.
4. Connect the earthing wire to earth.
* For earthing wire, green-and-yellow
insulation is required, and the cross-
sectional area of the conductor must
be more than 0.75 mm
2
or 18 AWG.
