What matters on the Automower 450V NERA
This NERA model may be installed with a physical boundary wire or, where supported/configured, a wire-free EPOS setup. The correct diagnostic branch depends on the installation actually in use.
Use the exact error text shown by the mower or app. Similar wording across mower generations does not always mean the same component has failed.
Start with these checks
- Move mower to clear flat area.
- Stop alarm using normal procedure.
- Inspect the exact stopping area.
- Remove raised obstacles/debris.
- If repeated on flat clear ground, record exact warning and seek service.
- Move the mower to a flat clear area.
Stop if: the mower has damaged wiring, a swollen/damaged battery, severe vibration, water inside electrical areas, or would require opening sealed electronics.
What this fault can mean
Lifted / alarm warning. Similar symptoms can have more than one cause, so work through the checks in order rather than replacing parts immediately.
Diagnostic decision
- Terrain/obstacle → correct area
- Repeats on flat ground → sensor/service diagnosis
