  Isolate the medium-voltage drive, lock out all sources and prove the stored energy discharged under the PowerFlex 7000 procedure.
• What should be inspected around the Allen-Bradley 81001-451-61-R position?
  Inspect the associated gate path, adjacent power components, cooling condition and mechanical interfaces without borrowing identity from another execution.
• Which controlled checks follow installation of Allen-Bradley 81001-451-61-R?
  Verify the as-left connections and mechanical installation, then observe PowerFlex 7000 diagnostics during the approved energization sequence.
