EU EMC Directive Apparatus vs Fixed Installations

Directive 2014/30/EU treats equipment as either apparatus or a fixed installation, and the category changes how conformity, marking, and evidence are handled.

Use this comparison to separate market-supplied end-user products from permanent site-specific installations and from apparatus made only for a particular fixed installation.

Overview

The EMC Directive uses the same essential EMC aim for equipment, but it does not treat every equipment project the same way. Apparatus is a finished appliance, combination, certain component or sub-assembly, or mobile installation that is made available for end use. A fixed installation is a permanent combination of apparatus and possibly other devices at a predefined location. That distinction drives CE marking, EU declaration, technical documentation, site records, and authority-response evidence.

Side-by-side comparison

Apparatus vs Fixed Installations under the EMC Directive

Use this table to 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.

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.

Directive 2014/30/EU on electromagnetic compatibility Guide for the EMCD (Directive 2014/30/EU)

Section 1

Classify the equipment before assigning EMC duties

Start with the commercial and technical fact pattern. 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 or more specific Union law controls the same EMC requirements.

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.

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 file 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. A folder of CE-marked component declarations may be enough for a simple installation only where it also provides the supplier instructions needed for installation, use, and maintenance. More complex or higher-risk sites need a more detailed site EMC rationale.

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.
