Diese Europäische Norm legt die technischen Anforderungen zur Minimierung der in Abschnitt 4 aufgelisteten
Gefährdungen fest, die bei Inbetriebnahme, Betrieb und Wartung von Ausrüstungen zur Bodenstromversorgung
auftreten können, wenn diese in Übereinstimmung mit den Anweisungen des Herstellers oder
seines Beauftragten ausgeführt werden. Sie berücksichtigt auch einige Funktions- und Gestaltungsanforderungen,
die von offiziellen Stellen, Luftfahrzeug- und Bodengeräteherstellern sowie Luftverkehrs- und
Wartungsgesellschaften als wesentlich erachtet wurden.
Diese Europäische Norm gilt für:
- Ausrüstungen zur Bodenstromversorgung, selbstfahrend oder schleppbar (Beispiele siehe Anhang A);
- Ausrüstungen zur Bodenstromversorgung, die auf anderen Luftfahrt-Bodengeräten montiert sind;
- Bodenstromzubehör für Ausrüstungen zur Bodenstromversorgung (einschließlich Zubehör für fest installierte
Geräte).
Diese Europäische Norm gilt nicht für:
- die elektrische Charakteristik der Versorgung, die Ausführung des Versorgungssystems und darauf bezogene
Maßnahmen gegen Kontakt;
- elektrische Versorgungssysteme, die nicht für Luftfahrzeuge bestimmt sind;
- elektrische Systeme an Bord von Luftfahrzeugen.
Diese Europäische Norm enthält keine Festlegungen hinsichtlich Lärm und Schwingungen.
Lärm und Schwingungen werden in EN 1915-4 und EN 1915-3 behandelt.
Diese Europäische Norm behandelt keine Gefährdungen, die von einem Serienfahrgestell und von anderen
Fahrzeugen auf dem Vorfeld ausgehen.
Dieser Teil von EN 12312 gilt nicht für Ausrüstungen zur Bodenstromversorgung, die hergestellt wurden,
bevor diese Europäische Norm durch das CEN veröffentlicht wurde.
!Es ist beabsichtigt, diesen Teil der EN 12312 in Verbindung mit EN 1915-1, EN 1915-2, EN 1915-3 (für

Overview
EN 12312-20:2005+A1:2009 (CEN) defines safety, functional and some performance requirements for electrical ground power units (GPUs) used to supply external electrical power to aircraft. The standard aims to minimise hazards during commissioning, operation and maintenance when carried out per manufacturer instructions. It applies to self‑propelled and towable GPUs, ground power equipment mounted on other GSE, and ground power accessories (cables, connectors, cable handling). It does not cover on‑board aircraft electrical systems, the electrical characteristics of supply networks, non‑aircraft electrical supply systems, or noise and vibration (these are addressed in EN 1915‑3/4).
Key topics and technical requirements
- Scope & exclusions: Clarifies applicability and that the Part is not retroactive to equipment manufactured before publication. Intended for use alongside EN 1915‑1/2/3/4.
- Hazard listing & risk reduction: Annex B lists hazards to be addressed using the risk‑assessment approach (EN ISO 12100).
- Power sources: Diesel generator sets must conform to EN 12601; turbines require overspeed, over‑temperature and low‑oil protection and speed regulation.
- Cables & connectors: Connectors must meet ISO 461‑1/2; cable assemblies require a minimum IPX4 ingress protection, adequate length and resistance to ramp fluids; interlocks must prevent energising unused connectors; cable stowage must prevent kinking and damage.
- Controls & safety devices: Emergency stops required at operator panels and shall meet EN ISO 13850 (category 0 or 1); E/F and N interlock bypass must be restricted and visibly indicated; visual/audible fault indicators required.
- Mechanical & vehicle requirements: Towable GPUs must be towable up to 32 km/h; self‑propelled units need driver accommodation, restraint systems and emergency exits; structural edges under bridges must be rounded (≥1 mm) where <2.5 m above ground.
- Marking & documentation: Permanent data plates (e.g., maximum continuous rated output) and comprehensive operating/maintenance instructions (connection procedures, hazards, training needs, emergency measures) are mandatory.
- Verification: Functional tests and measurements cover towing speed, turbine controls, interlocks, controls, brakes, steering and warnings per EN 1915‑1.
Applications and users
EN 12312-20 is used by:
- GSE manufacturers designing GPUs and accessories
- Airlines and ground handling operators procuring, operating and maintaining GPUs
- Airport authorities and safety managers setting operational procedures and workplace safety requirements
- Maintenance organisations and inspectors verifying compliance and performing functional tests
Practical uses include product design validation, procurement specifications, operator training content, and acceptance testing of new or modified GPU equipment.
