2) Power cable and grounding cable
The grounding/power cable of PLC should be treated as follows.
(1) The panel should be grounded with a thick wire() to secure a lower impedance even in high frequency.
(2) LG(Line Ground) terminal and FG(Frame Ground) terminal functionally let the noise inside the PLC flow into the ground,
so a wire of which impedance is low should be used.
(3) Since the grounding cable itself may generate noise, thick and short wiring may prevent it serving as an antenna.
11.1.3 Cable
1) Extension cable treatment
The extension cable of XGT series is with fast electric signal. Therefore, high frequency noise wave is emitted from the
extension cable. To comply with the CE specifications, please attach the ferrite core on the extension cable as presented
in the figure.
2) Fixing a cable in the panel
If the extension cable of XGT series is to be installed on the metallic panel, the cable should be 1cm and more away
from the panel, preventing the direct contact.
The metallic plate of panel may shield noise from electromagnetic wave while it a cable as a noise source is close to the
place, it can serve as an antenna. Every fast signal cable as well as the extension cable needs proper spacing from the
panel.
