Installing a Signal Cable
4.5
When laying out a signal cable, separate it from power cables and keep it away from strong
•
interference sources to prevent communication interruption.
•
Ensure that the protection 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.
•
Use a plug to block the idle cable hole with the waterproof rubber ring, and then tighten the
locking cap.
•
If multiple signal cables need to be connected, ensure that the outer diameters of the signal
cables are the same.
