Figure 15: Terminal Block
To connect the bare wires to the terminal block, attach the sensor cable wires to the color coded side of
the terminal block. Match the wire’s colors to the appropriately labeled terminals. If necessary, use
Figure 15 as a guide. The connections on the opposite side of the terminal are discussed in the
following subsections. If you cut the cable to shorten it, notice that both sets of twisted-pair wires
have drain wires inside their insulation. These drain wires (and the white wire that is not part of
the twisted pair) must be connected to the terminal labeled CLEAR. (Only necessary if you cut the
cable.)
Incorrect wiring can damage the sensor and void the warranty. Before applying power,
make sure all connections are correct and secure.
