LVD conformity: define the equipment and its electrical safety scope
Check rated voltage, exclusions, supplied configuration and manufacturer evidence before preparing an LVD conformity file.
Start with the supplied equipment
LVD 2014/35/EU addresses equipment designed for rated voltages between 50–1000 V AC or 75–1500 V DC, subject to its exclusions. Record input and output ratings, intended use, environment, accessories and the legal manufacturer. A marketing description such as low-voltage product is insufficient to establish the legal scope.
Separate equipment boundaries before selecting safety requirements. A power supply, the device it feeds and a marketed assembled system can require different assessments. Check other applicable legislation and exclusions rather than converting an LVD scope decision into a statement that every electrical obligation has been satisfied.
Hypothetical case: controller and mains adaptor
A supplier offers a 24 V DC controller together with a 230 V AC adaptor. Its file contains only the adaptor report. Obtain the actual supply arrangement, product labels, connection drawings and intended installation. The controller rating does not remove the adaptor from the analysis, and the adaptor evidence does not establish the safety of every completed assembly.
Prepare a boundary diagram and a model-specific requirements/evidence table. Identify unresolved integration effects, accessible parts and foreseeable misuse for technical review. Keep the release decision open where configuration or safety evidence is missing; do not label the bundle conforming merely because one component bears a CE mark.
Evidence and responsibility
For equipment within LVD scope, the manufacturer prepares technical documentation, performs or arranges the Annex III internal-production-control assessment and establishes continued production conformity. The file must connect risks, design solutions, calculations and reports to the actual product. A declaration and marking follow a supported conformity decision, not the purchase of a certificate.
Kayra can help organise the scope brief and evidence gaps. It does not grant an LVD approval or replace the manufacturer’s engineering decision. The next practical input is a controlled description of the supplied models and an agreed allocation of missing technical work; the competent authority retains its market-surveillance role.
