3.2.4 Grounding System for Communication Cable
We recommend to use proper Grounding System on the communication cable. The best way to ground the system is
to put the shield wire of the communication cable to the 1
st
class earth grounding; however due to the difficulty of
handling the earth ground, the installation cost will possibly increase.
There will be three grounding points to be found during installation;
1.
Earth Ground
2.
Chassis Round
3.
Power Ground
The most important point of Grounding System is to avoid grounding both ends of shield wires in order to prevent
noise being created (one could interfere the communication) from unequal voltage level.
A proper way to ground is to connect only one end of shield wire of communication cable to Grounding System; If you
find earth ground nearby, then connect one end of shield wire to earth ground; If you do not have earth ground nearby,
then find chassis ground and connect one end of shield wire to chassis ground; If you do not find both earth ground
and chassis ground, then connect one end of shield wire to power ground. (GND of FINGER007 series or 505R series)
Note:
if the chassis ground is not properly connected to the earth, the communication may get interfered. Therefore,
we recommend to use power ground instead of chassis ground.
