EU Low Voltage Directive Requirements

The LVD covers electrical equipment designed for use with a voltage rating between 50 and 1000 V for alternating current or between 75 and 1500 V for direct current. Equipment and phenomena listed in Annex II, such as electrical equipment for explosive atmospheres, radiology and medical purposes, lift electrical parts, electricity meters, domestic plugs and socket outlets, electric fence controllers, and radio-electrical interference, sit outside the Directive.

Article 3 and Annex I set the safety baseline: equipment must be constructed according to good engineering practice in safety matters in force in the Union and must not endanger people, domestic animals, or property when properly installed, maintained, and used for its intended application. Annex I first requires the characteristics necessary for safe use to be marked on the equipment or an accompanying document and requires safe assembly and connection; its hazard objectives then address both hazards arising from the equipment and hazards caused by external influences on it.

Manufacturers carry the design-and-conformity burden. They must ensure equipment is designed and manufactured against Annex I safety objectives, draw up technical documentation, carry out Module A internal production control, draw up the EU declaration of conformity, affix CE marking, keep the technical documentation and declaration for 10 years after placing on the market, and keep series production aligned with design, product, standard, and technical-specification changes. The LVD procedure is manufacturer-controlled; it does not itself require a notified-body certificate.

Importers must place only compliant equipment on the market and check that the manufacturer has completed conformity assessment, technical documentation, CE marking, required documents, and manufacturer identification. Distributors must act with due care and verify CE marking, required documents, instructions, safety information, and manufacturer/importer identification before making equipment available.

Annex III uses Module A internal production control. The manufacturer establishes technical documentation that allows assessment of conformity, includes an adequate analysis and assessment of risks, identifies applicable requirements, and covers design, manufacture, and operation as relevant. The manufacturer must also take the measures necessary so that manufacturing and its monitoring ensure conformity with the technical documentation and Annex I safety objectives.

The technical file should include a general description, design and manufacturing drawings, explanations needed to understand drawings and operation, a list of harmonised standards applied in full or in part, alternative technical solutions where standards are not applied, design calculation and examination results, and test reports. A test report is evidence within the file, not a substitute for the complete risk, design, manufacturing, and conformity rationale.

Conformity with a harmonised standard, or part, whose reference is published in the Official Journal gives presumption of conformity only for the Annex I safety objectives that it covers. Use remains voluntary. Record the exact standard, edition, amendment, OJEU status, scope, and any partial application or deviations; assess hazards and intended or reasonably foreseeable conditions that the standard does not cover. If no harmonised route is available, Articles 13 and 14 provide narrower routes for specified international or national standards, subject to their legal conditions.

The EU declaration must state that the Annex I safety objectives have been demonstrated, follow the Annex IV model structure, include the Module A elements, stay continuously updated, and be translated as required by the Member State where the equipment is placed or made available. CE marking is affixed before placing on the market, visibly, legibly, and indelibly to the equipment or data plate, or to packaging and accompanying documents where direct marking is not possible or warranted.

Instructions, safety information, and labelling must be clear, understandable, and intelligible. Manufacturers and importers must provide instructions and safety information in a language easily understood by consumers and other end-users, as determined by the Member State concerned; distributors must check that this material accompanies the equipment before making it available.

When an operator has reason to believe equipment it placed or made available is non-conforming, it must take corrective measures, withdraw, or recall the equipment as appropriate. Where the equipment presents a risk, the operator must inform the competent national authorities in the Member States where it made the equipment available, giving details of the non-compliance and corrective measures.

Market surveillance authorities may evaluate equipment presenting a risk, require corrective action, withdrawal, or recall, and share information with the Commission and other Member States where non-compliance is not limited to one national territory. The LVD also treats missing or incomplete CE marking, EU declaration, technical documentation, or Article 6 and Article 8 administrative information as formal non-compliance that authorities can require operators to end.
