Position the Boundary Wire
Lay out the Boundary Wire using your planned boundary and test the system BEFORE burying the wire or
attaching it to an existing fence. This will make any layout changes easier. Work carefully. A nick in the wire
insulation can diminish the signal strength and create a weak area where your dog can escape. Ensure you
have at least 10 feet between the wire and dangerous areas such as the street.
Avoid running the Boundary Wire parallel to and within 10 feet of electrical
wires, neighboring containment systems, telephone wires, television or antenna
cables, or satellite dishes The Fence Transmitter signal can couple on to buried
wires or cables causing the Receiver Collar to activate over the buried wires or
cables in the Pet Area. This may cause an inconsistent signal. If you must cross
any of these, do so at 90-degree angles (perpendicularly) (5A). In YardMax ®
mode, the boundary wire can be placed 2-3 feet from neighboring containment
systems (non-YardMax ® ) without interference.
If separating the wire by at least 10 feet from a neighboring containment
system’s wire does not reduce the inconsistent signal, contact the Customer
Care Center.
Underground cables can carry high voltage. Have all underground cables marked before you dig to bury your wire.
In most areas, this is a free service. Avoid these cables when you dig.

To Twist the Boundary Wire
Twisting the wire cancels the signal allowing your pet to cross over that area safely (5B). To
ensure the signal is cancelled, it is recommended that you cut and splice the wire between
each twisted section. The signal cannot be cancelled by running the wire through plastic
or metal piping. Splicing shielded cable to the wire will also not cancel the signal. Refer to
figure (5C) for the correct method for twisting the wire. Add approximately 4 inches for
every 10 feet of wire that you are planning to twist for your layout. You can twist your own
wire by cutting two equal lengths of 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 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
3 ⁄
8
inch of insulation off the ends of the wires to be spliced
(5D). Make sure the copper Boundary Wire is not corroded. If the 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 (5E). 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 (5F). Snap the lid of the capsule shut (5G). 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.
