This European Standard 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@ except variable reach trucks as defined in ISO 5053-1:2015@ 3.21 and 3.22@ straddle carriers as defined in ISO 5053-1:2015@ 3.18 and 3.19@ and specific functions@ parts and/or systems utilized for the automatic operation of driverless industrial trucks as defined in ISO 5053-1:2015@ 3.32. NOTE 1 Reference is made to this standard in other standards which cover the non-electrical requirements of the various industrial truck types. NOTE 2 This document only covers the integration of the standalone equipment to the industrial trucks. Other Directives and/or standards can apply to such equipment. NOTE 3 This standard does not cover driverless functions of industrial trucks. The requirements of this standard are valid@ when trucks are operated under the following climatic conditions: ?? defined in the applicable parts of the EN ISO 3691 series and the EN 16307 series; ?? relative humidity in the range 30 % to 95 % (not condensing). This standard deals with safety requirements for all electrical components of industrial trucks@ including electrically actuated hydraulic/pneumatic valves. 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 standard does not deal with all those requirements to reduce hazards which could occur: a) during construction; b) for industrial trucks that are required to operate in severe conditions (e.g. in extreme climates@ in freezer applications@ in hazardous environments); c) because of malfunction of not electric safety-related parts of control systems@ e.g. hydraulic and pneumatic elements like pistons@ not electric valves@ pumps etc. NOTE 4 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. This European Standard does not repeat all the technical rules which are state of the art and which are applicable to the materials used to build industrial trucks@ for which reference can be made to EN ISO 12100.
