C.2.2 The ‘Frame Ground’ and ‘Grounding 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, telecommunica-
tion networks, etc. Those individual grounding bars not only provide the
individual reference point, but also make the earth a our ground!
