EN 1648-1:2018 (E) 6 1 Scope This European Standard specifies safety, health and functional requirements for 12 V direct current (DC) extra low voltage (ELV) electrical installations for habitation aspects of caravans. It covers the design and integration of the caravan system with the towing vehicle system. It does not apply to commercial trailers; nor does it include requirements for ELV road lighting and signalling lamps and their installations, except for safety requirements for the routing of cables in LPG storage compartments. This European Standard also specifies the ELV output requirements of low voltage (LV) equipment that may be used to provide an ELV supply but it does not specify safety, technical and functional requirements for LV appliances and installations. Requirements for LV installations are specified in HD 60364-7-721. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

If several sources of supply are used it shall be ensured that there is no unfavourable interaction. 4.3 Auxiliary batteries 4.3.1 Type of battery An auxiliary battery shall be of the rechargeable type. 4.3.2 Terminals Auxiliary battery terminals shall be clearly and durably marked ò ªó and ò «òä Connections to auxiliary battery terminals shall be securely clamped or bolted to ensure continuous contact and shall be insulated unless the auxiliary battery is provided with an insulating cover. 4.3.3 Location An auxiliary battery shall be placed in a compartment according to 4.3.5, which is designed to protect it from mechanical damage, with easy access for maintenance and/or removal and secured to prevent movement of the battery, e.g. when the caravan is in motion. 4.3.4 Caravans without auxiliary battery If an auxiliary battery is intended to be used but not provided, then the position and instructions for the installation shall be included in the user's handbook according to Clause 8 and a notice shall be fixed in its compartment or near the proposed location. If a caravan is not designed to accept an auxiliary battery, it shall be clearly stated in the user's handbook. SIST EN 1648-1:2018
