  • Identify whether the equipment contains significant capacitance or a DC bus
  • Follow the OEM waiting-time guidance after power removal
  • Verify residual voltage with the correct meter before contact
  • Confirm any bleed/discharge path is intact if the design depends on it
  • Treat the circuit as energized until verified otherwise

This checklist is a reminder layer only. Follow the equipment-specific safety procedure and site LOTO process.

Trust Boundary — Engineering Judgment Required

This site is an independent educational reference for industrial automation standards. It paraphrases and organizes guidance in original language; it is not a substitute for the official published standards, professional engineering judgment, or legal review, and content has not been independently verified against current published editions.

Items marked Review pending await technical review against the identified edition. Items marked Planned have no reviewed source material behind them. Do not rely on this site for compliance determinations, safety-critical design decisions, or legal interpretation.
