Before SmartSensor Matrix is powered the wires from each sensor cable must be
correctly landed into the plug-in terminals (refer to Figure 2.5 and 2.6).
To land the sensor cables, use the following steps:
1. Properly strip back the cable jacket and shielding on the service end of the
cable.
2. Open the insulation displacement connector using a screwdriver. Insert the
wire leads into the bottom side of the plug-in terminal according to the color
code show in the following table and Figure 2.4. Make sure the wires are
bottomed in the terminal.
3. Close the insulation displacement connector using a screwdriver. The plug-in
terminals will automatically displace the insulation and complete the
electrical connection. (There is no need to manually strip the insulation on
the end of each wire.)
The insulation displacement connector plugs are keyed from left to right. The blue
socket can be used to visually see which plug goes into which terminal block. On
the leftmost terminal block, the PWR connection is blue (not gray like the others).
On the next terminal block, the GND connection is blue. The blue connection
continues to move one connection to the right as you move from left to right.
