3.2 Main components for installation
The installation involves the following components:
• A robotic lawn mower that mows the lawn
automatically.
• A charging station, which has 3 functions:
• To send control signals along the boundary
wire.
• To send control signals along the guide wire
so that the product can follow the guide wire
to specific remote areas in the garden and
can find its way back to the charging station.
• To charge the product.
• A power supply, which is connected to the
charging station and a 100-240V power outlet.
• Loop wire, which is laid around the work area
and around objects and plants that the product
must not run into. The loop wire is used both as
boundary wire and guide wire.
3.3 To prepare for installation
Read the installation chapter before you start the
installation. Prepare the installation carefully to make the
product operate satisfactorily.
• Make a blueprint of the work area and include all
obstacles. This makes it easier to examine where
to put the charging station, the boundary wire and
the guide wire.
• Make a mark on the blueprint where to put the
charging station, the boundary wire and the guide
wire.
• Make a mark on the blueprint where the guide wire
connects to the boundary wire. Refer to
To install
the guide wire on page 19
.
• Fill in holes in the lawn to make it level.
CAUTION: Holes with water in
the lawn can cause damage to the
product.
• Cut the grass before you install the product. Make
sure that the grass is maximum 10 cm / 4 in.
Note: The first weeks after installation the sound level
when the product cuts the grass can be higher than
usual. The sound level decreases after some time.
3.4 Before the installation of the wires
You can select to attach the wires with stakes or bury
them. You can use the 2 procedures for the same work
area.
CAUTION: If you use a dethatcher
in the work area, bury the boundary wire
and the guide wire to prevent them from
damage.
3.4.1 To examine where to put the charging
station
• Keep a minimum 2 m / 7 ft. of free space in front of
the charging station. Refer to
To examine where to
put the guide wire on page 17
.
• Keep a minimum of 150 cm / 60 in. of free space
to the right and left of the center of the charging
station.
• Put the charging station near a power outlet.
• Put the charging station on a level surface.
• The baseplate of the charging station must not be
bent.
max. 5 cm / 2"

13
• Put the charging station in an area with protection
from the sun.
• If the charging station is installed on an island,
make sure to connect the guide wire to the island.
Refer to
To make an island on page 16
.
3.4.2 To examine where to put the power
supply
CAUTION: Make sure that the blades
on the product do not cut the low-voltage
cable.
CAUTION: Do not put the low-voltage
cable in a coil or below the charging station
plate. The coil causes interference with the
signal from the charging station.
• Put the power supply in an area with a roof and
protection from the sun and rain.
• Put the power supply in an area with good airflow.
• Use a residual-current device (RCD) with a tripping
current of maximum 30 mA when you connect the
power supply to the power outlet.
Low-voltage cables of different lengths are available as
accessories.
3.4.3 To examine where to put the
boundary wire
CAUTION: There must be a barrier of
minimum 15 cm / 6 in. in height between
the boundary wire and water bodies, slopes,
precipices or public roads. This will prevent
damage to the product.
CAUTION: Do not let the product
operate on gravel.
CAUTION: Do not make sharp bends
when you install the boundary wire.
CAUTION: For careful operation
without noise, isolate all obstacles such as
trees, roots and stones.
The boundary wire should be put as a loop around the
work area. Sensors in the product senses when the
product approaches the boundary wire, and the product
selects another direction. All parts of the work area must
be maximum 35 m / 115 ft. from the boundary wire.
To make the connection easier between the guide wire
and the boundary wire, it is recommended to make an
eyelet where the guide wire will be connected. Make the
eyelet with approximately 20 cm / 8 in. of the boundary
wire.
Note: Make a blueprint of the work area before you
install the boundary wire and guide wire.

• If you have a paving stone path that is in level with
the lawn, put the boundary wire below the paving
stone.
Note: If the paving stone is minimum 30 cm / 12
in. wide, use the factory setting for the
Drive Past
Wire
function to cut all the grass adjacent to the
paving stone. Refer to
Drive Past Wire on page
26
.
• If you make an island, put the boundary wire that
runs to and from the island near together (E). Put
the wires in the same stake. Refer to
To make an
island on page 16
.
• Make an eyelet (F) where the guide wire is to be
connected to the boundary wire.
3.4.3.1 To put the boundary wire in a slope
The product can operate in 45% slopes. Slopes that are
too steep must be isolated with the boundary wire. The
gradient (%) is calculated as height per m. Example: 10
cm / 100 cm = 10%.
10 cm/ 4"
100 cm/ 40"
10%
• For slopes steeper than 45% inside the work area,
isolate the slope with boundary wire.
• For slopes steeper than 15% along the outer edge
of the lawn, put the boundary wire 20 cm / 8 in. (A)
from the edge.
• For slopes adjacent to a public road, put a barrier
of minimum 15 cm / 6 in. along the outer edge of
the slope. You can use a wall or a fence as a
barrier.
3.4.3.2 Passages
A passage is a section that has boundary wire on each
side and that connects 2 parts of the work area. The
distance between the boundary wire on each side in the
passage must be a minimum of 60 cm / 24 in.
Note: If a passage is less than 2 m / 6.5 ft. wide,
install a guide wire through the passage.
1439 - 015 - 23.11.2022 Installation - 15
The recommended minimum distance between the
guide wire and the boundary wire is 30 cm / 12 in. The
product always runs to the left of the guide wire as seen

.
6.7 Finding breaks in the loop wire
Breaks in the loop wire are usually the result of
unintentional physical damage to the wire such as when
gardening with a shovel. In countries with ground frost,
also sharp stones that move in the ground can damage
the wire. Breaks can also occur due to the wire being
stretched excessively during installation.
Mowing the grass too low right after the installation can
damage wire insulation. Damage to the insulation may
not cause disruptions until several weeks or months
later.
CAUTION: Always select the maximum
cutting height the first weeks after
installation and then lower the height one
step at a time every second week until the
desired cutting height has been reached.
A defective splicing of the loop wire can also lead to
disruptions several weeks after the splice was done.
A faulty splice can, for example, be the result of the
coupler not being pressed together hard enough with a
pair of pliers, or that a coupler of lower quality than the
original coupler has been used.
Note: Please first check all known splices before
further troubleshooting is done.
A wire break can be located by gradually halving the
distance of the loop where the break may have occurred
until there is only a very short section of the wire left.
The following method does not work if
ECO mode
is
activated. Make sure first that
ECO mode
is turned off.
Refer to
ECO mode on page 24
.
1. Check that the indicator lamp in the charging
station flashes blue, which indicates a break in the
boundary loop. Refer to
LED indicator lamp on the
charging station on page 42
.
44 - Troubleshooting 1439 - 015 - 23.11.2022
2. Check that the boundary wire connections to the
charging station are properly connected and not
damaged. Check that the indicator lamp in the
charging station is still flashing blue.
AR
AL
G1
POWER
3. Switch the connections between the guide wire
and the boundary wire in the charging station.
Start by switching connection AL and G1. Some
models have additional guide wires . The same
procedure can be followed for them.
If the indicator lamp is lit with a solid green light,
then the break is somewhere on the boundary wire
between AL and the point where the guide wire is
connected to the boundary wire (thick black line in
the illustration).
Guide
GUIDE
AL
To rectify the fault you will need boundary wire,
connector(s) and coupler(s):
a) If the suspected boundary wire is short then it
is easiest to exchange all of the boundary wire
between AL and the point where the guide wire is
connected to the boundary wire (thick black line).
b) If the suspected boundary wire is long (thick
black line) then do as follows: Put AL and G1
back to their original positions. Then disconnect
AR. Connect a new loop wire to AR. Connect the
other end of this new loop wire at the middle of the
suspected wire section.
1439 - 015 - 23.11.2022 Troubleshooting -
45
AR
If the indicator lamp now is green, then the
break is somewhere in the wire between the
disconnected end to the point where the new wire
is connected (thick black line below). In that case,
move the connection for the new wire closer to
the disconnected end (roughly at the middle of
the suspected wire section) and check again if the
indicator lamp is green.
Continue until only a very short section of the wire
remains which is the difference between a solid
green light and a flashing blue light. Then follow
instruction in step 5 below.
4. If indicator lamp still flashes blue in step 3
above:Put AL and G1 back in their original
positions. Then switch AR and G1. If indicator lamp
now is lit with a solid green light then disconnect
AL and connect a new boundary wire to AL.
Connect the other end of this new wire at the
middle of the suspected wire section. Follow the
same approach as in 3a) and 3b) above.
5. When the break is found, the damaged section
must be replaced with a new wire. Always use
original couplers.
