EU EMC Directive Apparatus vs Fixed Installations

Classify the equipment before choosing the EMC route. Apparatus normally needs product conformity assessment, an EU declaration of conformity, and CE marking; a fixed installation instead needs site-specific engineering and operating-life records.

The narrow exception for apparatus made only for one identified fixed installation does not apply when that apparatus is otherwise made available on the market.

Overview

Classify the equipment before choosing the EMC evidence route. Apparatus is a finished appliance or combination made available as one functional unit for an end user; certain end-user components, sub-assemblies, and mobile installations are also treated as apparatus. A fixed installation is a particular combination of several types of apparatus and, where applicable, other devices, assembled for permanent use at a predefined location. Apparatus normally follows the conformity-assessment, EU declaration of conformity, and CE-marking route. The fixed installation itself does not follow that apparatus marking route; the responsible person must instead document site-specific good engineering practices for as long as the installation operates.

Side-by-side comparison

Apparatus vs Fixed Installations under the EMC Directive

This table helps decide whether the EMC work belongs in a product conformity route, a site-specific installation route, or both.

Review all sources
First framework
Apparatus

A finished appliance, qualifying combination, component or sub-assembly, or mobile installation made available for end use and capable of causing or being affected by electromagnetic disturbance.

Second framework
Fixed installations

A particular combination of apparatus and, where relevant, other devices that is assembled, installed, and intended to be used permanently at a predefined location.

Comparison row 1

Scope boundary

Apparatus

Focus on the product or combination supplied as a single functional unit for the end user, including components or sub-assemblies intended for end-user incorporation and mobile installations.

Fixed installations

Focus on the permanent site combination, its geographical boundary, its external interfaces, and the electromagnetic environment at the predefined location.

Operational implication

Draw the product boundary and the site boundary separately. A product may be apparatus even when it will later be incorporated into a fixed installation.

Comparison row 2

Market event

Apparatus

The apparatus route turns on making available or placing apparatus on the Union market, including the first making available of apparatus.

Fixed installations

A fixed installation is put into service as a site installation rather than placed on the market as apparatus.

Operational implication

Use apparatus checks for commercial supply of end-user equipment; use fixed-installation checks for the installed site combination.

Comparison row 3

Trigger

Apparatus

Apparatus is intended for the end user and must be assessed for normal intended operating conditions and representative configurations.

Fixed installations

A fixed installation is intended for permanent use at a defined location and must respect the intended-use information for its components.

Operational implication

Do not classify only by hardware type. The intended user, intended use, mobility, and location permanence are part of the EMC category decision.

Comparison row 4

Core obligations

Apparatus

The manufacturer designs and manufactures for Annex I essential requirements, prepares technical documentation, performs or has performed the conformity assessment, draws up the EU declaration of conformity, and affixes CE marking.

Fixed installations

The person responsible for the fixed installation documents good engineering practices and keeps that documentation available for national authorities while the installation operates. The fixed installation itself is not CE marked or covered by an EU declaration of conformity under the apparatus route.

Operational implication

Apparatus compliance is a product conformity route. Fixed-installation compliance is a site engineering and documentation route; CE-marked incorporated apparatus does not establish compliance of the installed combination by itself.

Comparison row 5

Evidence record

Apparatus

Keep the apparatus EMC assessment, risk analysis, design and manufacturing information, applied harmonised standards or other technical specifications, examinations, test reports, EU declaration, CE marking evidence, instructions, and traceability information.

Fixed installations

Keep the installation boundary, component instructions, EMC environment assumptions, interface analysis, cable and screening choices, earthing or bonding approach, filters or other mitigation, maintenance assumptions, and responsible-person record.

Operational implication

A fixed-installation file may reference apparatus declarations and instructions, but it still needs site evidence showing how the installed combination meets EMC requirements.

Comparison row 6

Timing and deadlines

Apparatus

If apparatus is made available generally, all relevant apparatus provisions apply even if the apparatus will be incorporated into a fixed installation.

Fixed installations

If apparatus is intended for incorporation into a particular fixed installation and is otherwise not made available on the market, Articles 6 to 12 and 14 to 18 are not compulsory for that apparatus, but special accompanying documentation is required.

Operational implication

Use the Article 19 exception narrowly. The evidence must identify the fixed installation, its EMC characteristics, and incorporation precautions.

Comparison row 7

Standards and engineering basis

Apparatus

Harmonised standards published for the EMC Directive can support presumption of conformity for apparatus to the essential requirements they cover.

Fixed installations

A fixed installation may use standards, codes of practice, and component instructions as part of good engineering practice, but the site-specific conditions still matter.

Operational implication

For apparatus, track the standards applied in the technical documentation and EU declaration. For fixed installations, record why the chosen practices fit the actual site.

Comparison row 8

Overlap and reuse

Apparatus

Choose apparatus when the immediate question is whether an end-user product can be supplied, CE marked, declared, imported, distributed, or supported on the Union market.

Fixed installations

Choose fixed installation when the immediate question is whether a permanent site combination has been installed with suitable EMC practices and documented for the responsible person.

Operational implication

Choose both when market-supplied apparatus is incorporated into a permanent site installation; keep the product evidence and site evidence linked but distinct.

Comparison row 9

Authority response

Apparatus

For apparatus, authorities may request information and documentation needed to demonstrate conformity, and non-conforming apparatus can require corrective action, withdrawal, or recall.

Fixed installations

For fixed installations, authorities may request evidence where there are indications of non-compliance, especially disturbance complaints, and may require measures to bring the installation into compliance.

Operational implication

Prepare different response packs: a product technical file for apparatus and a site compliance file for fixed installations.

Practical decision rule

How should teams decide between apparatus and fixed-installation evidence?

  • If the item is commercially supplied for end use, build the apparatus evidence pack before placing it on the Union market.
  • If the issue is a permanent site combination, build the fixed-installation record around good engineering practice, component intended-use information, site boundaries, interfaces, and the responsible person.
  • If a bespoke item is only for one particular fixed installation and is otherwise not made available, document why the Article 19 specific-apparatus route applies and keep the required accompanying documentation.

Section 1

Classify the equipment before assigning EMC duties

Start with the commercial and technical facts. If the item is supplied on the Union market as a single functional unit for an end user and it can generate or be affected by electromagnetic disturbance, treat it as apparatus unless an exclusion applies or another Union law lays down the same EMC requirements more specifically.

If the project is a site-specific combination assembled and intended to stay permanently at a predefined location, treat the site combination as a fixed installation. The incorporated apparatus normally keeps its apparatus duties, unless the narrow Article 19 case applies for apparatus intended only for a particular fixed installation and otherwise not made available on the market.

For example, a commercially supplied combination of programmable logic controllers and motor drives can be one apparatus when it is sold as a single functional unit for an end user; combining CE-marked products does not automatically make that system EMC-compliant. A factory production line assembled for permanent use at one identified site can be a fixed installation. A mobile installation is treated as apparatus, not as a fixed installation. These are category examples, and the marketed unit, intended user, mobility, and site facts still control the result.

  • Record whether the item is made available on the Union market, placed on the market for the first time, or only incorporated into one identified fixed installation.
  • Check whether the intended user is an end user, an installer or integrator, or the person responsible for a fixed installation.
  • Separate the apparatus technical file from the fixed-installation site file so CE marking evidence is not confused with site engineering evidence.

Section 2

Documentation differs by route

For apparatus, the manufacturer must support conformity before placing the apparatus on the market. The record should cover the EMC assessment, applicable harmonised standards or other technical solutions, risk analysis, test reports where relevant, EU declaration of conformity, CE marking, identification, contact details, instructions, and specific installation or use precautions.

For fixed installations, the central record is not a product CE-marking file. It should show the installation boundary, incorporated apparatus and other devices, component instructions used, EMC environment, good engineering practices applied, precautions, responsible person, and any evidence needed if authorities request proof following disturbance complaints or other indications of non-compliance.

  • Keep apparatus technical documentation and the EU declaration of conformity for 10 years after the apparatus is placed on the market.
  • Keep documented good engineering practices for the fixed installation for as long as the installation is in operation.
  • For specific apparatus used only in a particular fixed installation, include the apparatus identity, manufacturer or importer details, the fixed installation identity and EMC characteristics, and incorporation precautions.

Section 3

Good engineering practice is a fixed-installation control

A fixed installation must be installed using good engineering practices and the information on the intended use of its components. In practical EMC records, that means defining the installation boundary, external interfaces, conducted and radiated disturbance paths, cable and screening choices, earthing or bonding approach, filters or protection devices, and immunity measures for sensitive equipment.

This is site-specific evidence. CE markings and declarations for incorporated apparatus do not, by themselves, show that the installed combination meets the fixed-installation requirements. For a simple installation, the record may be limited to the suppliers' installation, use, and maintenance instructions plus evidence that the installer followed them. A complex installation needs enough additional analysis to show why the chosen practices fit the site and its electromagnetic environment.

  • Do not use a fixed-installation file as a substitute for apparatus conformity assessment where market-supplied apparatus is involved.
  • Do not assume a CE-marked apparatus makes the whole fixed installation compliant without checking site coupling, interfaces, intended use, and installation precautions.
  • Revisit the site record when equipment, cabling, location, power supply, radio environment, operating mode, or maintenance assumptions change.
