11 Installing the Perimeter Wire
► Route the perimeter wire to block off narrower areas in
which a < 39.4 in. (100 cm).
► If you route the perimeter wire in a confined area,
deactivate the passage function (offset drive home),
15.3 or install a search loop,
11.6 Routing Around Restricted Areas
A restricted area is an area that the robotic mower must
avoid, including obstacles that cannot be mowed or objects
that the mower can't bump off of to change direction, such
as flower beds, trees with buttressed roots, etc.
► Install a restricted area around such obstacles.
► To ensure a robust operation, install restricted areas in a
round shape - no oval, angular or inwardly curved shapes.
► Maintain the wire clearance a = 11 in. (28 cm) around the
obstacle (2) to prevent the robotic mower from scraping
against the obstacle (2).
► Install the perimeter wire (1) with the aid of the
iMow Ruler (3) as illustrated.
► The diameter of any restricted area must be at least 22 in.
(56 cm) and no more than 9.8 ft. (3 m).
► Keep a minimum clearance of b = 17.4 in. (44 cm)
between the perimeter wire routed around a restricted
area and the perimeter wire at the edge of the mowing
area.
► Keep a minimum clearance within a radius of at least
c = 6.6 ft. (2 m) around the docking station (1).
► Route the perimeter wire from the edge to the obstacle
with the proper clearance.
► Route the perimeter wire around the obstacle (2) and
attach it to the ground using a sufficient number of wire
stakes (3). Observe the installation direction (arrows).
► Then route the perimeter wire back to the edge. The
segment of perimeter wire routed back to the edge (4)
must be laid directly next to the segment leading to the
restricted area. Keep the segments parallel. When the
wire is laid side-by-side, the signal is canceled and the
iMow will mow directly over this section of perimeter wire.
