Known limits
What this record does not prove.
- Designed-to-meet language is not a completed certificate and must remain qualified.
- Current limits are temperature-conditioned and do not establish robot peak-load suitability.
- No RCI pack, charger, enclosure, cycle, transient or safety test exists.
