TIP
This symbol denotes a protective earth ground terminal which
provides a low impedance path between electrical circuits and earth
for safety purposes and provides noise immunity improvement. This
connection must be made for safety purposes on AC-powered
controllers.
This symbol denotes a functional earth ground terminal which
provides a low impedance path between electrical circuits and earth
for non-safety purposes, such as noise immunity improvement.
ATTENTION: When you connect or disconnect the Removable
Terminal Block (RTB) with field side power applied, an electrical arc
can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
