Chapter 4. Installation and Wiring
When there is concern about noise penetration, use an insulation shield transformer or a noise filter.
Be sure to twist the wiring of the input power supply as short as possible and do not let the wiring of the shielding transformer or
noise filter pass through the duct.
When using a magnetic contactor (MC) for AC / DC, it is recommended to use Ferrite Core at the power input terminal.
EX) Apply a ferrite core to the power terminal as shown in the figure.

4.2.2 Ground Wiring
(1) This XGT Panel has enough noise countermeasures, so it can be used without grounding except when there is a lot of noise.
However, when grounding, please refer to the following.
(2) Grounding should be done by dedicated grounding as much as possible.
Grounding works are classified as class 3 grounding (grounding resistance 100 Ω Or less).
(3) When dedicated grounding is not possible, use common ground as shown in Fig.
A) Exclusive ground: Best B) Common ground: Good C) Common ground: Bad
(4) Ground wire is 2 mm
2
or more. If possible, place the grounding point near the XGT Panel to shorten the length of the ground
wire.
If the grounding condition is bad or connected as in (C), the XGT Panel may malfunction or communication failure
may occur. Be sure to check grounding.
