26、t (DC) extra low voltage (ELV) electrical installations for habitation aspects of motor caravans. It applies only to installations which are electrically connected with the electrical installation of the base vehicle or which can be electrically connected with it by means of change-over devices. Thi
27、s 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 6036

33、fixtures 3 Terms and definitions For the purposes of this document the terms and definitions given in EN 13878:2003 apply. 4 Power supply 4.1 General The power supply shall be a nominal DC 12 V (minimum 11 V and maximum 15 V) obtained from an auxiliary battery, except in the case of a motor caravan
34、where the overall length multiplied by the overall width does not exceed 8,5 m2plan area. In this case, it is permissible to use only the base vehicle battery. BS EN 1648-2:2012EN 1648-2:2012 (E) 7 NOTE A power supply with a nominal voltage different than DC 12 V is not allowed. The supply of the au
35、xiliary battery shall be obtained from the electrical installation of the base vehicle or from one or more of the following sources: a) battery charger (see 7.4); Where the charger is combined with an AC/DC converter (see d) and 4.3.1) fixed within the motor caravan, then individual items of current
36、 using equipment can also be supplied with electricity directly from this AC/DC converter. b) generator that is driven by any form of energy (see 4.3); c) solar energy cells (see 4.3); d) LV supply via an on-board mounted AC/DC converter (e.g. transformer, switching power supply) that complies with
37、the requirements of the relevant standards in accordance with directive 2006/95/EC and subsequent amendments. It shall be ensured that the auxiliary battery will be automatically disconnected from the 12 V power supply of the base vehicle when the engine of the base vehicle is turned off. If several
38、 sources of supply are used it shall be ensured that there is no unfavourable interaction. 4.2 Auxiliary batteries 4.2.1 General An auxiliary battery shall only be intended for the electric power supply of the living area. 4.2.2 Type of battery An auxiliary battery shall be of the rechargeable type.
39、 Non-rechargeable batteries are not auxiliary batteries according to 4.2. They may be used however, provided that they are used in circuits separated from other sources of electrical supply. 4.2.3 Capacity An auxiliary battery shall have a minimum capacity of at least 60 Ampere-hours (Ah) at 20 h di
40、scharge rate. NOTE It is recommended to use a battery designed to be discharged over long periods at a relatively low current. 4.2.4 Terminals Auxiliary battery terminals shall be clearly and durably marked “+” and “. Connections to auxiliary battery terminals shall be securely clamped or bolted to
41、ensure continuous contact and shall be insulated unless the auxiliary battery is provided with an insulating cover. 4.2.5 Location If an auxiliary battery is not installed in the engine compartment, it shall be placed in a compartment according to 4.2.6, which is designed to protect it from mechanic
42、al damage, with easy access for maintenance and/or removal and secured to prevent movement of the battery, e.g. when the motor caravan is in motion. 4.2.6 Auxiliary battery compartment An acid resistant liquid tight tray shall be installed under an auxiliary battery whose electrolyte is liquid capab
43、le of holding at least 20 % of the electrolyte capacity of the recommended battery, when in place. BS EN 1648-2:2012EN 1648-2:2012 (E) 8 The interior of an auxiliary battery compartment shall be ventilated and protected against the corrosive effect of acid-laden gases, either by a) installing a seal
44、ed auxiliary battery that incorporates an external ventilating kit that is taken to the exterior of the motor caravan; or b) installing an auxiliary battery in an enclosed battery compartment that is protected internally against corrosion and is ventilated directly to the exterior of the motor carav
45、an by means of a suitable tube in accordance with the battery manufacturers instructions or as supplied by the manufacturer of the auxiliary battery; or c) ventilating the compartment at both low-level and high-level to the exterior of the motor caravan. The construction of the compartment shall hav
46、e gas tight joints and seams, including the sides of the ventilator openings, be of acid-resistant material or have an anti-corrosive finish. The minimum size of ventilation shall be not less than 80 mm2at low level and not less than 80 mm2at high level. If the compartment opens into the interior of
47、 the motor caravan, the lid shall provide an air seal. The requirements concerning the protection against corrosion and ventilation are not applicable if batteries with bound electrolytes are used. If an auxiliary battery is not provided, then the position and instructions for the installation of th
48、e battery and compartment, in accordance with a), b) or c), shall be included in the Users Handbook according to Clause 8 and a notice shall be fixed in or near the proposed location stating: “For instructions on auxiliary battery installation, see Users Handbook”. When the manufacturer makes no pro
49、vision for the installation of an auxiliary battery, the following statement shall be made in the Users Handbook: “This motor caravan has not been designed to accommodate an auxiliary battery. Do not fit one.” For underslung battery, a minimum ground clearance shall be observed in compliance with directive 2007/46/EC, Annex II. 4.2.7 Warning notice A warning notice shall be fixed in a prominent position near the auxiliary battery or
