Mounting the Controller
The controller is mounted internally. Choose a convenient spot away from high-voltage,
high power cables and electronics. Use 4-40 metal screws to mount the controller.
The controller should be mounted in line with the sensor flex tail exit point to minimize
flexing. Refer to Figure 1 for more details on controller mounting.
