Use an insulation shielding transformer or noise filter when the electromagnetic interference occurs.
Keep the stripped ends of the terminated cables twisted and as short as possible. When running the wiring avoid
running the cables for the insulation shielding transformer or noise filter pass through the cable duct.
When you use the magnetic lighting contactor (MC) for AC/DC, it is recommended to use a ferrite core close to
the power terminals as shown below.
10.2.2 Ground wiring
(1) Our XGT Panel has enough anti-noise measure, so except that there are many noises specially, the
ground is not needed. When you use the ground connection, refer to the following information.
(2) Use the exclusive ground connection. When you install the ground connection, use the third grounding
resistance (less than 100Ω).
(3) If you cannot use the exclusive ground connection, use the common ground connection like below.
A) Exclusive ground: Best B) Common ground: Good C) Common ground: Poor
(4) Use cables for grounding/earth connections by using cable with a cross sectional area greater than 2.0 ㎟.
Install the ground connection as close as possible to the XGT Panel.
Check and test the grounding connection. If the connection is bad or in case of (B) above, the XGT Panel
may malfunction or the communication signals may fail.
