ÖNORM EN 1459-7

This document specifies electrical safety requirements for electrical systems of rough-terrain variable-reach trucks and slewing rough-terrain variable-reach trucks powered by one or more electric motors (hereafter referred to as trucks), namely pure electric and hybrid electric trucks, including when hydraulic systems are electrically powered. This document applies to electrical systems with maximum voltage greater than 32 up to 1500 V DC or greater than 21 up to 1000 V AC r.m.s. This document deals with all significant hazards, hazardous situations and events relevant to the trucks when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. The significant hazards (see EN ISO 12100:2010, Annex B) dealt with in this document are listed in Annex A. This document does not deal with hazards which could occur: - during construction; - when operating trucks in potentially explosive atmospheres. This document does not cover: - electrical systems of trucks with maximum working voltage up to 32 V DC or 21 V AC r.m.s (see relevant requirements in EN 1459-1 or EN 1459-2, as applicable); - electric regenerative braking systems; - electrical systems of externally-powered trucks designed for operation only when mains-connected. NOTE Electrical systems of trucks designed to be both externally-powered and self-propelled are covered in this document when not mains-connected. This document does not deal with sales literature. This document does not address hazards specifically related to: - trucks designed to operate with varying levels of autonomy (autonomous trucks), including trucks which move autonomously to the charging station, or when truck has embedded safety-systems with fully or partially self-evolving behaviour or logic using machine learning approaches; - trucks with communication network connection. This document is not applicable to trucks manufactured before the date of its publication.
