Requirements for Labeling Elevator Distribution Boxes

Fibre interconnection and data room reference Published 29 Nov 2025

Use this reference to prepare product questions for FD SOLUCIONES. Check interfaces, capacity, protection and installation requirements against the current product documentation.

Elevator distribution boxes must be labeled with permanent, legible, and code-compliant data plates or tags that convey electrical ratings, safety warnings, and operational information. Key Standards and GuidelinesUL Marking and Labeling Systems: Labels for electrical equipment, including elevator distribution boxes, must meet permanency and durability requirements to ensure they remain legible under operational conditions. Labels should convey electrical ratings, installation instructions, and safety warnings, and be compatible with the surface and environmental conditions of the equipment.

UL-recognized labeling systems are tested for adhesion, temperature tolerance, and chemical resistance.

IS

O 28219: 2017: This standard defines item marking and direct part marking for components, including machine-readable (1D/2D barcodes) and human-readable information. For elevator distribution boxes, ISO 28219 ensures that labels can be scanned or read for inventory, maintenance, and safety purposes, supporting traceability and compliance across the supply chain. Labels may combine multiple types of information in a single area or use separate labels for clarity.

ASM

E A17. 1 / CSA B44: Elevator codes require data plates and tags on controllers, main line disconnects, and car crossheads. Labels must be permanently attached, legible, and conform to specified letter height and stroke.

For freight elevators, signage must indicate passenger restrictions. The code also specifies placement locations to ensure visibility during inspection and maintenance.

NFP

A 70E / OSHA Compliance: Electrical safety standards require labeling to alert personnel to hazards, including potential arc flash risks. Labels must be durable, high-performance, and clearly visible, especially on energized equipment. The equipment owner is responsible for installation, maintenance, and updating of labels.

Label Content and Placement Recommendations

Electrical Ratings: Voltage, current, phase, and frequency. Safety Warnings: Arc flash, shock hazards, and operational cautions. Operational Instructions: Controller identification, disconnect locations, and maintenance notes.

Identification Codes: Serial numbers, part numbers, or barcodes for traceability. Placement: On the controller door, main disconnect, or inside the car crosshead for visibility during inspection. Labels should not obstruct access and must remain legible under normal environmental conditions.

Materials and Durability

Use high-performance, chemical- and abrasion-resistant materials. Ensure permanent adhesion to metal or painted surfaces. Consider temperature and moisture exposure in material selection.

Machine-readable codes (barcodes or QR codes) should comply with ISO 28219 for scanning reliability.

Summary

Elevator distribution box labeling must comply with UL, ISO, ASME, and NFPA standards, ensuring safety, traceability, and operational clarity. Labels should be permanent, legible, and strategically placed, containing electrical ratings, warnings, operational instructions, and identification codes. Using high-quality materials and following code-specified placement ensures compliance and enhances safety for maintenance personnel and inspectors.
