Connecting Frame Earth

IMPORTANT
Connect the frame of the 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.
* Use an earthing wire that has a conductor with a cross-sectional area of at least 0.75 mm
AWG. Green-and-yellow insulation is required.
• Be sure to comply with all applicable laws, regulations, and guidelines.
• Proper earthing is very important to protect the PBX from external noise and to reduce the risk
of electrocution in the event of a lightning strike.
• The AC cable's earthing pin may not be enough to protect the PBX from external noise and
lightning strikes. A permanent connection must be made between earth and the earth terminal
of the main unit.
