How to Label Robot Wiring Before Troubleshooting

Follow the approved shutdown and power-isolation procedure for the exact robot. Account for batteries, capacitors, moving mechanisms and other stored energy.

Use competent supervision when the safe state or circuit boundaries are unclear.

Compare the physical build with the current wiring diagram, controller documentation and component labels. Record discrepancies before changing anything.

Do not infer polarity, voltage or pin function from wire colour alone.

Give each cable or harness a stable identifier and place matching labels near both connection points without covering safety markings, vents or moving parts.

Choose materials and positioning suitable for the actual environment; a generic label is not guaranteed to withstand heat, movement or chemicals.

Log the source, destination, connector orientation and relevant circuit reference. Photograph the arrangement where authorised and useful.

A photograph supports traceability but does not establish electrical correctness or compatibility.

Define the observed fault, expected behaviour and approved test method. Change or disconnect only what the responsible supervisor has authorised.

Do not probe live circuits or improvise test methods beyond the learner’s competence and the hardware instructions.

Replace outdated labels and revise the diagram or build log after an approved wiring change. Quarantine damaged or unidentified parts for review.

Is wire colour enough to identify a circuit? No. Should labels be placed at both ends? Usually, where safe and practical. Can a label prove compatibility? No.
