Ground Bar .
Figure C-2: Grounding Bar Grounding is one of
the most important issues for our system. Just like Frame Ground of the
computer, this signal offers a reference point of the electronic circuit
inside the computer. If we want to communicate with this computer,
both Signal Ground and Frame Ground should be con- nected to make
a reference point of each other’s electronic circuit. Gener- ally speaking, it
is necessary to install an individual grounding bar for each system,
such as computer networks, power systems, telecommuni- cation
networks, etc. Those individual grounding bars not only provide the
individual reference point, but also make the earth a our ground!
