Drawing the ground line
The ground line can be drawn:
• From the connector to which the communication cable is
connected.
Insert the ground line into the hole to which the shield line is
inserted and fix them together.
• From a T-branch tap.
Connect only the ground line to one connector on a T-branch tap.
• By using a cable clamp.
Ground the shield of a communication cable with a cable clamp
and use the same clamp panel for grounding of the power supply
for communication.
CAUTION
Be sure to connect the shield line of each
communication cable. If all shield lines are not
connected, the shielding effect of the whole
network will be reduced.
