Safety of industrial trucks - Electrical/electronic requirements

Edition date: 2025-11-19
In Force
Available languages: English
Summary: This document specifies the electrical requirements for the design and construction of the electrical installation in self-propelled industrial trucks that are within the scope of ISO 5053-1:2020, except rough-terrain variable-reach trucks as defined in ISO 5053-1:2020, 3.21 and 3.22, straddle carriers as defined in ISO 5053-1:2020, 3.18 and 3.19, and all those functions utilized for the automatic operation of driverless industrial trucks as defined in ISO 5053-1:2020, 3.32. It provides the electrical/electronic and safety-related parts of control system requirements for those self-propelled industrial trucks identified above. NOTE 1 For detailed information about the electrical/electronic requirements for driverless trucks see EN ISO 3691-4:2023, 4.1.3. NOTE 2 Reference is made to this document in other standards which cover the non-electrical requirements of the various industrial truck types. This document deals with safety requirements for all electrical and electronic components of industrial trucks, including electrically actuated hydraulic/pneumatic valves. It specifies minimum performance levels required for safety functions realized by safety related parts of control systems. It is intended to be used to avoid or minimize hazards or hazardous situations listed in Annex I. These situations can arise during the operation in the area of use for which it is designed and during maintenance of trucks in accordance with the specifications and instruction given by the manufacturer. This document does not deal with hazards which could occur: - during construction; - when operating in potentially explosive atmospheres; - because of malfunction of non-electric safety-related parts of control systems, e.g. hydraulic and pneumatic elements like pistons, non-electric valves, pumps, etc.; - when operating outside the range of 30 % to 95 % (not condensing) of relative humidity. NOTE 3 The level of the defined required performance for electrical safety related control systems can be used as a guideline to determine the performance of non-electric systems. NOTE 4 Hazards due to penetration of water and dust are covered by the definition of PLr of safety functions, according to EN ISO 13849-1:2023. NOTE 5 Safety measures outside the scope of the electrical/electronic system are covered by other safety standards e.g. EN ISO 3691 series and EN 16307 series.

Le présent document spécifie les exigences électriques pour la conception et à la fabrication de l'installation électrique dans les chariots de manutention automoteurs relevant du domaine d'application de l'ISO 5053-1:2020, à l'exception des chariots tout-terrain à portée variable définis dans l'ISO 5053-1:2020, 3.21 et 3.22, des chariots cavaliers définis dans l'ISO 5053-1:2020, 3.18 et 3.19, et toutes ces fonctions servant au fonctionnement automatique des chariots de manutention sans conducteur définis dans l'ISO 5053-1:2015, 3.32. Il fournit les exigences applicables aux parties électriques/électroniques et relatives à la sécurité du système de commande pour les chariots de manutention automoteurs identifiés ci dessus. NOTE 1 Pour des informations détaillées concernant les exigences électriques/électroniques pour les chariots sans conducteurs voir l’EN ISO 3691-4 :2023, 4.1.3. NOTE 2 Il est fait référence au présent document dans d'autres normes traitant des exigences relatives aux différents types de chariots de manutention dans des domaines autres que l'électricité. Le présent document traite des exigences de sécurité s'appliquant à tous les composants électriques et électroniques des chariots de manutention, y compris les distributeurs hydrauliques/pneumatiques électriques. Il spécifie les niveaux de performance minimaux requis pour les fonctions de sécurité réalisées par les parties des systèmes de commande relatives à la sécurité. Il est destiné à être utilisé afin d'éviter ou de réduire au minimum les phénomènes dangereux ou les situations dangereuses énumérés à l'Annexe I. Ces situations peuvent survenir pendant l'utilisation dans la zone à laquelle ils sont destinés et pendant la maintenance des chariots conformément aux spécifications et aux instructions données par le fabricant. Le présent document ne traite pas des phénomènes dangereux qui peuvent se produire : - pendant la fabrication ; - lors du fonctionnement dans des atmosphères explosibles ; - en raison d'un dysfonctionnement des parties relatives à la sécurité non électriques des systèmes de commande, par exemple, des éléments hydrauliques et pneumatiques tels que les pistons, les distributeurs non électriques, les pompes, etc. ; - en cas de fonctionnement en dehors de la plage de 30 % à 95 % (sans condensation) d'humidité relative. NOTE 3 Le niveau de performance requis défini pour les systèmes de commande relatifs à la sécurité électriques peut servir de ligne directrice pour déterminer les performances des systèmes non électriques. NOTE 4 Les phénomènes dangereux dus à la pénétration d'eau et de poussière sont couverts par la définition du PLr des fonctions de sécurité, conformément à l’EN ISO 13849-1:2023. NOTE 5 Les mesures de sécurité en dehors du domaine d'application du système électrique/électronique sont couvertes par d'autres normes de sécurité, par exemple, la série EN ISO 3691 et la série EN 16307.

Dieses Dokument legt die elektrischen Anforderungen für die Auslegung und die Herstellung der elektrischen Anlage von selbstfahrenden Flurförderzeugen im Anwendungsbereich von ISO 5053-1:2020 fest, mit Ausnahme von Flurförderzeugen mit veränderlicher Reichweite wie in ISO 5053-1:2020, 3.21 und 3.22 definiert, Portalhubwagen wie in ISO 5053-1:2020, 3.18 und 3.19 definiert und spezifischen Funktionen, Teilen und/oder Systemen für den automatischen Betrieb von fahrerlosen Flurförderzeugen wie in ISO 5053-1:2020, 3.32 definiert. Es stellt die elektrischen/elektronischen und sicherheitsbezogenen Teile der Anforderungen an die Steuerungssysteme für die genannten selbstfahrenden Flurförderzeuge zur Verfügung. ANMERKUNG 1 Auf dieses Dokument wird in anderen Normen, die die nichtelektrischen Anforderungen verschiedener Typen von Flurförderzeugen behandeln, Bezug genommen. Dieses Dokument behandelt Sicherheitsanforderungen für alle elektrischen und elektronischen Komponenten von Flurförderzeugen einschließlich elektrisch betätigter Hydraulik-/Pneumatikventile. Es legt die Mindest-Performance Level für Sicherheitsfunktionen fest, die von sicherheitsbezogenen Teilen von Steuerungen realisiert werden. Es soll die in Anhang I aufgeführten Gefährdungen oder Gefährdungssituationen verhindern oder so gering wie möglich halten. Diese Situationen können beim Betrieb in dem nach der Auslegung bestimmten Einsatzbereich entstehen und bei der Instandhaltung von Flurförderzeugen entsprechend den Spezifikationen und Anweisungen des Herstellers. Dieses Dokument behandelt keine Gefährdungen, die auftreten könnten: a) während der Herstellung; b) bei Betrieb in explosionsgefährdeten Bereichen; c) aufgrund einer Fehlfunktion von nicht sicherheitsbezogenen elektrischen Teilen von Steuerungssystemen, z. B. hydraulischen und pneumatischen Elementen wie Kolben, nichtelektrische Ventile, Pumpen usw.; d) bei Betrieb außerhalb des Bereichs von 30 % bis 95 % (ohne Betauung) relativer Luftfeuchte. ANMERKUNG 2 Die für sicherheitsbezogene elektrische Steuerungssysteme definierten erforderlichen Performance-Level können als Leitfaden für die Festlegung der Performance von nichtelektrischen Systemen verwendet werden. ANMERKUNG 3 Gefährdungen durch Eindringen von Wasser und Staub sind durch die Definition von PLr von Sicherheitsfunktionen nach EN ISO 13849-1:2015 abgedeckt.
