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 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.
