10 Installing the Robotic Mower
NOTICE
Use only perimeter wire and wire stakes authorized by 
STIHL.
NOTICE
The maximum distance between the robotic mower and any 
perimeter wire must not be more than 55 ft. (17 m), since 
otherwise the wire signal is no longer recognizable.
NOTICE
Especially when installing with a wire laying machine, make 
sure that the perimeter wire runs loosely from the spool. 
Avoid pulling on the perimeter wire. Tensile stress can lead 
to wire breaks.
The perimeter wire (1) is installed on the ground and fixed in 
place with wire stakes (2) every 3.3 ft. (1 m). Stakes may 
need to be closer together if the ground is uneven. This 
prevents the wire from being cut by the mower blade.
To install the perimeter wire around an internal docking 
station:
► Secure the perimeter wire (1) with a wire stake (2) on the 
left side (A) or on the right side (B) of the docking station, 
next to a wire channel in the base plate.
► Leave a section of wire (1) with a length of approximately 
a = 4.92 ft. (1.5 m). This segment will later be connected 
to the docking station.
► Install the perimeter wire on the left side (2) and on the 
right side (1) of the docking station (3) in a straight line 
with a length of a > 23.6 in. (60 cm) and at right 
angles (90°) to the base plate.
► If the "Passage" feature ("Offset Drive Home") in the 
installation settings is activated (@ 15.3), this section of 
perimeter wire (a) must be longer, at least a = 4.9 ft. 
(1.5 m).
