product.

CAUTION: Use original spare parts and
installation material.
Note: Refer to www.husqvarna.com for more
information about installation.
Automower® 550 has the Automower® Club Solution where you can use 2 or 3 products in the same installation, refer to Automower® Club Solution on page 18.
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.

· 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.

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.

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: 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.

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.

Note: Make a blueprint of the work area before you
install the boundary wire and guide wire.

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 POWER AL
G1
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).

AL GUIDE
Guide
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

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

AR

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.

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.
