PDU-A Safety Label – 3" × 1.5" White on Red

Engraved label reading "PDU-A", 3" × 1.5", white text on a red background. Mark the cabinet with a "PDU-A" label so it is never confused with its partner unit.

For use on the A-side PDU cabinet, its output breaker panel and the racks it feeds.

Names a power distribution unit and tells the reader it is the A unit, usually one side of an A and B feed pair. It lets staff keep the two feeds straight.

Where it's used: Typically on the front of the PDU cabinet, on its output breaker panel and sometimes at the racks it feeds in a data room.

• Wording: "PDU-A" (1 line, bold lettering)
• Size: 3" × 1.5" (76 × 38 mm), a small plate with room for two clear lines.
• Color: White text on a red background. White on red is the usual pick for stop, fire, emergency and shut-off functions.
• Mounting: Peel-and-stick industrial adhesive back with no holes. Clean and dry the surface, then press it firmly in place.
• Material: 1/16" (1.6 mm) two-ply engraving plastic with a matte finish. The wording is engraved through the top color to the contrasting core, so it can't rub off like printed ink.
• Corners: Square-cut corners and clean edges.

Make the A and B labels at the same time and check that the names match the rack power labels downstream. Usually ordered by data center technicians and electrical contractors. Also called: PDU A label, power distribution unit A, A-side PDU tag.
