outer jacket to cover the end of the shield wire.
If wiring 2 cables in a daisy-chain configuration, twist together the shield wires, then wrap the shield wires
with tape.
7 Insert the other 4 wires into the sensor's screw terminal connector. If wiring 2 cables, insert like-colored wires
into each terminal.

Allow no more than 0.06 inch (1.5 mm) bare communication wire to protrude. If bare
communication wire contacts the cable's foil shield, shield wire, or a metal surface other than the terminal
block, the device may not communicate correctly.
