• The proper grounding (connection to the earth ground) is very important to protect the
system from the bad effect of external noise or to reduce the electric shock of a lightning
strike.
• The GND pin of the 3-pin type AC cable has an effect against the external noise or the
lightning strikes, but it may not be enough to protect the system. A complete connection of
the GND terminal of the PBX system to the earth ground is strongly recommended.
