Frame Earth Connection
IMPORTANT!
Connect the frame of the Hybrid IP-PBX to earth.
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
•
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.
