If excessive noise is present, or becomes evident after installation, check the integrity of the
sensor cable installation. In particular, ensure that there is no inadvertent ground connection to the
coaxial cable shield at either end of a splice connection or terminator. Verify that the center
conductor and shield have not been swapped at the terminal block.
Sensor cable/lead-in cable connections
An enclosure that is installed on a post on the protected fence can use a direct connection to the
sensor cable. If the enclosure is installed away from the protected fence, or away from the start of
the sensor zone, then the connection to the processor must be made with lead-in cable. The lead-
in cable is spliced to the sensor cable at the start point of the zone. The sensor cable to processor
connections are made on removable terminal blocks. First, prepare the cables. Then install the
cables in the terminal block and connect the terminal block to the sensor cable inputs (Flex
Channel A, Flex Channel B). Sensor cable and lead-in cable connections are made exactly the
same way.
