Potential instrument damage. Delicate internal electronic components can be damaged by static electricity,
resulting in degraded performance or eventual failure.

To install the module and connect the sensor, refer to the illustrated steps that follow and the wiring
table 

Table 1

.

Be sure to connect all sensor ground/shield wires to the controller enclosure grounding screws.

Note: If the sensor cable is not long enough to reach the controller, an interconnect cable and junction box are
required to extend the distance.
