DO YOU REALLY KNOW THE BOUNDARY WIRE FOR THE ROBOT LAWN MOWER?
How to Lay Automatic Lawn Mower Cables
You can lay the boundary wire above or below the ground. On the ground, you can better correct the position. Also, after a few weeks, the cable will grow too long to really be seen.
When preparing, you need to pay attention to obstacles in the area where the robot is mowing. For example, these can be stones, tree roots or garden ponds. You have to plan later.
Also make sure to keep the correct distance from the patio or bed. You can find the exact size of these sizes from the manufacturer's specifications. The distance to the terrace is usually specified as 5 to 10 cm, and the distance to the bed is about 30 cm.
Started laying cables at the charging station for the automatic lawn mower. Make sure there are no waves when laying the boundary wire. Fix about every 70 cm. Reconnect the end of the cable to the charging station. Make sure the cables are not crossed.
If you lay the cable underground, it usually needs to be about four centimeters deep. In most cases, robotic lawnmowers can also recognize cables that are a little deeper. The advantage of this variant is that, among other things, the cables are better protected. However, installation is more complicated and subsequent changes are cumbersome.
Neatly laid boundary wires also help ensure that the automatic lawn mower manages a clean lawn edge
How do boundary wires work?
The boundary wire starts from the charging station, where it is subjected to extremely low voltage. This creates a magnetic field that the robotic lawnmower can also recognize when the cable is laid in the ground. A signal stops the robot from traveling over the cable and out of the defined area. After the cable is completely routed around the surface, it ends up on the other side of the charging station.
Boundary wires are laid from the automower's charging station around the lawn area to be mowed and any obstructions, and back to the charging station. The wires are under low tension, creating a magnetic field. A lawnmower robot can use this as a guide.
Preparing to lay the border
To ensure that the installation runs smoothly and fulfills its purpose later, there are some preliminary considerations. The first question, of course, is whether you want to run the cable above ground or underground. In any case, it is advisable to start with an above ground variant, as it can still be changed if it becomes apparent that it needs to be changed. After a few weeks, you can still consider running the cable underground.
Above-ground and underground installations
Even if the cable ends up being laid underground, experts recommend laying it above ground first so that changes can still be made. It is important that the wires do not cross at any point under any circumstances.
When laying on the ground, use the fastening hooks at a distance of 30-75 cm, making sure the wire is directly on the ground so that the robotic lawnmower does not damage the wire later. Once the cable is connected, it only takes a few weeks before it disappears completely from being recognized by the robotic lawnmower.
Clean your lawn regularly, preferably considering burying it in the ground. This can even be done under paving stones. We recommend limiting the depth to about 10 cm instead of the 20 cm normally possible in normal soils. You should not put the cable directly under the stone, but plan a thin buffer layer between the stone and the sand cable, or use an empty conduit directly.
