11 Installing the Perimeter Wire
► Maintain the wire clearance a = 11 in. (28 cm)  at the 
corners around high obstacles such as wall corners or 
high flowerbeds (2). This keeps the robotic mower from 
scraping against the obstacle.
► Install the perimeter wire (1) with the aid of the 
iMow Ruler (3) as illustrated.
► Maintain the wire clearance a = 11 in. (28 cm) at the inner 
corner of a high obstacles such as walls or high 
flowerbeds (2). This keeps the robotic mower from 
scraping against the obstacle.
► Install the perimeter wire (1) with the aid of the 
iMow Ruler (3) as illustrated.
11.4 Measuring Wire Clearances at Corners
In tapered corners (< 90°) the perimeter wire should be 
installed as shown. The two angles must be at least one 
length of the iMow ruler (a = 11 in. (28 cm)) apart so that the 
robot mower can drive down the edge.
11.5 Routing the Perimeter Wire in Confined Areas
The robotic mower can travel automatically though narrow 
passages, provided the minimum wire clearances are 
maintained.
► If you route the wire between obstacles higher than 0.4 in. 
(1 cm), e.g. walls or hedges, keep a minimum wire 
clearance of one length of the iMow ruler (b = 11 in. 
(28 cm)).
► If you route the wire between obstacles lower than 0.4 in. 
(1 cm), e.g. paths or patios, keep a minimum wire 
clearance of c = 17.4 in. (44 cm).
