Another way of grounding is from the D.Station module connected near the center of
the network. As the drain terminal of the D.Station module is not grounded, this
grounding is done as follows: (1) uncover the braided shield of the communication
cable, (2) solder a ground wire to it, (3) attach an M3 solderless terminal to the free end
of the ground wire, and (4) connect the solderless terminal to the cable shield
connection terminal on the mount base of the D.Station module.
Communication cable
Uncover the braided shield of the
communication cable and attach
a ground wire to the braided shield.
Do not connect the ground wire to the drain terminal of the open connector
which already has a drain wire connected as shown below.

Figure 6-15 Prohibited Uncovering Method of Braided Shield

Do not ground the communication and power cable together. If grounded
together, power noise may be induced into the communication cable through
the ground wire.
