1.1本标准规定了以下称为卡车的电动助力工业车辆电气设备的设计和施工的电气和相关机械安全要求，卡车系统的额定电压高达240 V.附件A是规范性的， “牵引电池连接器”。附件B是规范性的，包含“电动机 - 输出和试验规则”，附件C是规范性的，包含“电磁接触器”。 注1:参考其他标准中的本标准，涵盖各种工业卡车类型的非电气要求。 注2本标准不涉及牵引电池充电的主题（CENELEC TC 21X正在准备电池充电的安全标准）。 注3:本欧洲标准不涵盖在潜在爆炸性环境中操作的特殊要求。 1.2本标准的要求适用于卡车在以下气候条件下运行时: - 连续工作的平均环境温度:25°C; - 最高环境温度，短期（长达1小时）:40°C; - 适用于正常室内条件的卡车的最低环境温度:5°C; - 最低环境温度

1.1 This standard specifies electrical and related mechanical safety requirements for design and construction of the electrical installation in battery powered industrial trucks hereinafter referred to as trucks, with nominal voltages of the truck system up to 240 V. The Annex A is normative and gives requirements for "Connectors for traction batteries". Annex B is normative and contains "Electric motors - Output and test rules" and Annex C is normative and contains "Electromagnetic contactors". 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 standard does not address the subject of charging of traction batteries (CENELEC TC 21X is preparing safety standards for battery charging). NOTE 3 The special requirements for operation in potentially explosive atmospheres are not covered in this European Standard. 1.2 The requirements of this standard are applicable, when trucks are operated under the following climatic conditions: - Average ambient temperature for continuous duty: +25°C; - Maximum ambient temperature, short term (up to 1 h): +40°C; - Lowest ambient temperature for trucks intended for use in normal indoor conditions: +5 °C; - Lowest ambient temperature for trucks intended for use in normal outdoor conditions: -20 °C; - Altitude: up to 2000 m; - Relative humidity: in the range 30 % to 95 % (non condensing). 1.3 This standard covers specific hazards (listed in clause 4), which could occur during the intended use of trucks. For hazards occurring during construction, transportation, commissioning, decommissioning and disposal, reference should be made to EN ISO 12100-2:2003.
