. 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 400 m (1300 ft). See the Replacement
Parts section in the sensor manual for part number information.
