Perimeter Wire Setup
1.0 Where To Start
In order to determine the best location to begin the setup, it is best to first make some basic
decisions based on your lawn. For each zone that is set up, allow for placement of one Perimeter
Switch for that zone. Find a convenient spot outside the perimeter of each zone, but a location that
is relatively easy for you to access. A spot sheltered from the elements is preferred
1.1 Using The Roboruler
There are two basic measurements that are used on the Roboruler. The shorter distance is used
along perimeter edges where the area outside the immediate perimeter (about 12 inches/30 cm) is
free of obstacles and is the same relative height as the perimeter edge. The longer distance is used
along perimeter edges where the area outside the immediate perimeter has obstacles or differences
in the height along the perimeter edge. See Figure 1.1.

1.2 Starting The Perimeter Wire
Tear out the perforated center piece on the perimeter wire box. Puncture the plastic covering with
your finger and feel around inside the center of the wire spool for the end of the wire. Pull the wire
end out of the box. The box is designed as a dispenser for the wire so do not remove the wire spool
from the box. After reviewing the illustrations and instructions in the following pages you will be
ready to lay out the perimeter wire and start pegging it to the ground. Figure 1.2
Leave enough wire at the beginning, where the Perimeter Switch is going to be located. Use the
Roboruler to help guide you on placement of the wire along the perimeter. Use a minimum number
of pegs at this point, as you will want to test the wire position at the end of the setup. See Section
2.5 for details on testing the setup.
