Additional Boundary Wire
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 at 1-800-732-2677.
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.

Connect the Wires to the Fence Transmitter
Boundary Wire (4A)
1. Run the Boundary Wire to the Fence Transmitter through a window, under a door,
through a crawl space vent, or any other appropriate available access. You can also
drill a hole through your wall.
2. Strip 3/8 inch of insulation from the ends of the Boundary Wire.
3. Press the red tabs on the Fence Transmitter and insert the twisted wire into the
Boundary Wire Terminals. Make sure the wires do not touch each other at the terminals.
4. Turn the Boundary Width Control knob to 10. This will set the Boundary Width at the
maximum width.
5. Plug the Power Adapter into the Power Jack and AC Power Outlet.
6. The Power Light and Loop Indicator Lights should come on. If this does not happen,
see the “Troubleshooting” section.

• Do not install, connect, or remove your system during a lightning storm. If the storm is close enough
for you to hear thunder, it is close enough to create hazardous surges.
• Risk of electric shock. Use the Fence Transmitter indoors in dry location only.
If possible, DO NOT use an AC circuit protected with a Ground Fault Circuit Interrupter (GFCI) or
Residual Current Device (RCD). In rare cases, nearby lightning strikes may cause the GFCI or RCD to
trip. Without power your dog may be vulnerable to escape. You will have to reset the GFCI or RCD to
restore power to the system.
For added protection, when unused for long periods of time or prior to thunderstorms, unplug from the
wall outlet and disconnect the loop boundary wires. This will prevent damage to the transmitter due to
surges.
Surge Protection
Lightning strikes within 1-2 miles of your installation can create current surges or spikes which may damage your
unprotected electronic pet containment system. The LP-4100-1 Surge Protector is designed to protect your In-Ground
Fence
™
from surges or spikes that can reach it via your AC power connection and/or your buried Boundary Wire.
Important: Standard Surge Protectors will not protect the Transmitter because they do not contain protection for
the Boundary Wire. Nearly all damage to the Transmitter results from power surges or spikes traveling through the
Boundary Wire and not the power adapter.
You may purchase a Surge Protection Kit through the Customer Care Center. The Surge Protection Kit protects the
system against surges that travel through the power source and/or the Boundary Wire.
