It also addresses hazardous stored energy and possible backfeed. Apply the rules relevant to the project\u2019s jurisdiction through the responsible qualified personnel.<\/p>\n<p>Translate that distinction into the project record. \u201cMains unavailable\u201d describes a supply event. \u201cBattery operation\u201d describes a continuity mode. \u201cController stopped\u201d describes a control state. None, by itself, defines a service boundary that has been established and verified.<\/p>\n<p>Do not use an extinguished display, an inactive output or a software stop command as the record\u2019s evidence of electrical isolation. Likewise, a supply\u2019s hold-up specification describes functional output behavior under stated conditions; it is not a personnel-safety discharge instruction.<\/p>\n<\/section>\n<section id=\"example\">\n<h2><span class=\"ez-toc-section\" id=\"A_hypothetical_handoff_that_reveals_a_missing_document\"><\/span>A hypothetical handoff that reveals a missing document<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Consider a panel intended to keep its controller operating during a mains outage. The service request is to replace the supply. The drawing identifies the incoming mains feed and battery assembly, but the draft maintenance sheet mentions only the incoming mains switch.<\/p>\n<p>The document review outcome is \u201cprocedure incomplete.\u201d It is not a finding that the AD-155B is unsuitable. The panel owner must provide an approved task-specific procedure that addresses the battery and any other applicable sources, with the required verification and restoration controls.<\/p>\n<p>A separate continuity test may intentionally demonstrate operation from the battery. Keep its report separate from the service authorization record: successful backup operation shows that the source can remain effective when mains is absent. It does not authorize a person to work inside that energized boundary.<\/p>\n<p>This is a planning example, not a WEHO customer installation or a measured test. Its useful result is the missing-document decision made before maintenance begins.<\/p>\n<\/section>\n<section id=\"release-record\">\n<h2><span class=\"ez-toc-section\" id=\"Release_the_source_map_with_the_equipment_revision\"><\/span>Release the source map with the equipment revision<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The completed handoff should let a qualified reviewer trace each source to a drawing, each service task to an approved procedure, and each open item to a named owner. The source map supplements those procedures; it does not replace their required sequence or verification method.<\/p>\n<p>Retain the panel identifier, schematic revision, supply model, battery assembly revision, task boundary, procedure identifiers and reviewer date. Include the actual records required by the equipment owner rather than inventing a universal acceptance voltage or waiting interval.<\/p>\n<p>Revisit the map when adding remote I\/O, a second supply, a battery extension or another powered interface. A small functional change can alter which parts remain energized even when the original maintenance sheet still appears correct.<\/p>\n<p>For procurement, ask who supplies the final panel-level service documentation and who approves changes.
