Installation

3.4 Connecting/Wiring the Sensor Cable

The sensor cable is supplied with a keyed quick-connect fitting for easy attachment to the controller, see Figure 3-19.Retain the connector cap to seal the connector opening in case the sensor must be removed. Optional extension cables may be purchased to extend the sensor cable length. If the total cable length exceeds 100 M (300 ft), a termination box must be installed. See the Replacement Parts section in the sensor manual for part number information.
