Installing the Signal Cable
4.6
•
When laying out the signal cable, separate it from the power cable and keep it away from
strong interference sources to avoid strong communication interference.
•
Ensure that the protective layer of the cable is inside the connector, that excess core wires
are cut off from the protection layer, that the exposed core wire is totally inserted into the
cable hole, and that the cable is connected securely.
