prevent ground potential difference
.
▪
The maximum transmission distance may be limited. Maximum recommended
cable length is 30m
.
▪
The CATx cable
must not be cut or crimped when it is connected

Ground loop
▪
Theriskofgroundloopissueshouldbeminimizedwiththesebestpractices.
▪
The CATx cable should run on a
similar path as the power lines and safety ground wire
.Thisistominimize

▪
The connected source and sink devices at the two endpoints should have the
same Earth potential
