• When laying out a signal cable, separate it from power cables to avoid strong signal
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.
• Block the unused cable hole using a cap and tighten the cable gland.
• If more than one signal cables are required, ensure that they have the same outer diameter.
