11 Installing the Perimeter Wire
► Keep a minimum clearance between obstacles lower than 
0.4 in. (1 cm), paths/obstacles that can be travelled on, of 
b=9in. (22cm).
► Route the perimeter wire (1) parallel to the ground and 
attach it to the ground with a sufficient number of wire 
stakes (2).
► Install a gate, which is a funnel-shaped entrance and exit 
area at the start and the end of the corridor. Keep the 
following distances:
–c=2.4in. (6cm)
– d = 9 in. (22 cm)
– e = 9 in. (22 cm)
The iMow will not enter the corridor unintentionally.
► Install the perimeter wire (1) in a straight line on the left 
and right side of the corridor entrance. The straight line 
must be at least one length of the robotic mower.
► Use the tunnel-shaped STIHL Corridor Pattern (C) to 
install the gate at each end of the corridor.
► When using the "Passage" feature ("Offset Drive Home"), 
search loops must be installed in the linked area in order 
for the iMow to be able to locate the gate and return to the 
docking station, @ 11.9.
► Define at least 1 starting point in the linked area, @ 15.6.
► If necessary, activate automatic edge mowing or mow the 
corridor area manually on a regular basis, @ 14.3 and 
@ 15.3.
Corridor Installation Example
The docking station (1) is installed in the primary mowing 
area (A). A linked mowing area (B) is linked to the primary 
mowing area with a corridor (2). The perimeter wire (3) can 
be followed by the robotic mower. To ensure mowing of the 
linked mowing area, two starting points (4) were defined.
11.9 Installing Search Loops
If the "Passage" function ("Offset Drive Home") is activated, 
search loops must be installed to help the robotic mower 
recognize the location of an external docking station, a 
corridor or a confined area. If the robotic mower crosses a 
search loop during its drive home, the robotic mower will 
then directly travel to the perimeter wire and to the docking 
station or through the corridor or confined area.
