Keep the system records together
Save equipment model details, warranty documents, the accepted scope, handover instructions and service history. Follow the instructions for the actual products installed.
Report symptoms clearly
Record the fault message, when it started, the loads in use and recent changes. Photographs of accessible displays and equipment labels can help an initial review. Avoid opening equipment or working on live wiring.
- Describe the symptom and when it occurs.
- Share equipment models and approximate installation age.
- Explain any changes in runtime or charging.
- Request an inspection for unfamiliar faults or damaged equipment.
