2.2 Installation of the Hybrid IP-PBX
48 Installation Manual
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., laws, 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 a lightning strike.
The earthing wire of the AC cable has an effect against 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.
