2-12 Installation and Wiring
To wire your module follow these steps.
1. At each end of the cable, strip some casing to expose the
individual wires.
2. Trim the signal wires to 2-inch (5 cm) lengths. Strip about 3/16
inch (5 mm) of insulation away to expose the end of the wire.
3. At one end of the cable, twist the drain wire and foil shield
together, bend them away from the cable, and apply shrink
wrap. Then earth ground at the preferred location based on the
type of sensor you are using. See Grounding on page 2-8.
4. At the other end of the cable, cut the drain wire and foil shield
back to the cable and apply shrink wrap.
5. Connect the signal wires to the terminal block. Connect the
other end of the cable to the analog input device.
6. Repeat steps 1 through 5 for each channel on the module.
ATTENTION
!
Be careful when stripping wires. Wire
fragments that fall into a module could cause
damage at power up.
