Installation
3.5.1 Connecting the sc Sensor in a Non-hazardous Location
3.5.1.1 Attaching a sc Sensor with a Quick-connect Fitting
The sensor cable is supplied with a keyed quick-connect fitting for
easy attachment to the controller, see
Figure 17 . 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. When used with
the termination box, the maximum cable length is 1000 m (3000 ft).
See the Replacement Parts section in the sensor manual for part
number information.
