Frame Earth Connection - Panasonic KX-TDA600 Installation Manual

2.2 Installation of the Hybrid IP-PBX

2.2.10 Frame Earth Connection

IMPORTANT
Make sure to separately connect the frame of each shelf to a different earth terminal. Do not
connect it to other shelves.
1.
Loosen the screw.
2.
Insert an earthing wire (user-
supplied)*.
3.
Tighten the screw.
4.
Connect the earthing wire to
earth.
5.
Repeat steps 1 to 4 for each
shelf.
* For earthing wire, green-and-yellow insulation is required, and the cross-sectional area of the conductor
must be more than 0.75 mm
• 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 each Hybrid IP-PBX must be made.
