Husqvarna Automower 405XE NERA: Outside work area

What this fault means

The mower believes it is outside the permitted work area.

Safety: Stop the mower and follow the manufacturer safety instructions before physical inspection.

Step-by-step checks

1. Move the mower well inside the work area and clear the message.
2. For wired installations, confirm the boundary wires are on the correct station pins and islands were laid in the correct direction.
3. Inspect slopes/obstacles close to the boundary and increase clearance where the mower can physically cross the loop.
4. For EPOS installations, inspect the virtual boundary near slopes/obstacles and verify positioning quality.
5. If it happens everywhere rather than one location, treat it as signal/polarity/positioning rather than a local terrain fault.
