WARNING
•
Proper earthing (connection to earth) is very important to reduce the risk to the user of
electrocution or to protect the PBX from the bad effects of external noise 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 PBX. A permanent connection between earth and the earth
terminal of each PBX must be made.
CAUTION
•
Make sure to separately connect the frame of each shelf to a different earth terminal. Do not connect
it to other shelves.
•
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.
Notice
Be sure to comply with applicable local regulations (e.g., laws, guidelines).
