1. Open the sensor side covers and then detach the plug-
gable connectors from the sensor PCB and prepare the
twisted shielded pair cable connecting (see Figure 13).
Figure 13. EAFR-01 Sensor Connection Step 1.
2. Before connecting the cable to connector, make sure
that the connecting order is correct (+, signal, shield).
The appropriate pins information is shown on the blue
bottom part of the sensor. Plug the wires into connec-
tor and fasten them by using a screw driver (see Figure
14).
