To Twist the Boundary Wire

Twisting the Boundary Wire cancels the signal and allows your pet to cross over that area

safely (4B). To ensure the signal is cancelled, it is recommended that you cut and splice the

Boundary Wire between each twisted section. The signal cannot be cancelled by running

the wire through plastic or metal piping. Splicing shielded cable to the Boundary Wire will

also not cancel the signal. Refer to figure (4C) for the correct method for twisting the wire.

You can twist your own wire by cutting two equal lengths of Boundary Wire supplied and

twisting them together. Anchor one end of the wires to something secure and insert the

other end in a power drill. Pull the wire taut. The drill enables you to twist the wire quickly.

Twist the Boundary Wire 10 to 12 times per foot to cancel the signal. Once you have

completed your boundary layout, insert the twisted wire into the transmitter.

To Splice or Repair the Boundary Wire

If you need additional Boundary Wire to expand your wire loop, you will

need to splice the wires together. Note the locations of all splices for future

reference.
Strip approximately

be spliced (4D). Make sure the copper Boundary Wire is not

corroded. If the Boundary Wire is corroded, cut it back to expose clean copper wire.
Insert the stripped ends into the wire nut and twist the wire nut around the wires. Ensure

that there is no copper exposed beyond the end of the wire nut. Tie a knot 3 to 4 inches

from the wire nut (4E). Ensure that the wire nut is secure on the wire splice.
Once you have securely spliced the wires together, open the lid of the gel-filled splice

capsule and insert the wire nut as deeply as possible into the waterproof gel inside the

capsule (4F). Snap the lid of the capsule shut (4G). For proper system performance, the

splice connection must be waterproof.
If your splice pulls loose, the entire system will fail. Make sure your splice is secure.

Additional gel-filled splice capsules and wire nuts are available through the Customer

Care Center.

Extra direct burial Boundary Wire can be purchased in 500 foot spools

at the store where you purchased the kit or through the Customer

Care Center.
Note: When adding Boundary Wire, it must act as a continuous loop.
The table at right indicates the approximate length of Boundary Wire

needed for a square, Single Loop layout. Length will vary due to the

amount of twisted wire and layout used.
