Chapter 10. Installation and Wiring
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.
(1) 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.
