AS ISO 11862 pdf download.Earth-moving machinery — Auxiliary starting aid electrical connector
1  Scope
This International Standard specifies the details, dimensions and design of both plug (male) and receptacle (female) which must mate properly to permit interchangeable use of different makes of electrical connectors providing an auxiliary starting circuit for earth-moving machinery as defined in ISO 6165. It lays down a universal connecting device, with correct polarity, standard circuit coding and protection from electrical shorts, which may also be used with any other machinery, vehicle or automotive equipment with the same electrical system voltage range.
2  Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 6165:1987, Earth-moving machinery — Basic types — Vocabulary. ISO 9247:1990, Earth-moving machinery — Electrical wires and cables — Principles of identification and marking. IEC 228:1978, Conductors of insulated cables.

3  General requirements
3.1  Receptacle The receptacle assembly shall be as shown in figure 1 and shall be permanently installed in a machine. The receptacle contains the male terminals [see figure 3 b)]; the configuration shall provide positive means of ensuring correct polarity when coupled with the mating plug. 3.2  Plug assembly The plug assembly shall be as shown in figure 2; it provides auxiliary starting from one machine to another [see figure 2 a)], or from an external power source,
4  Construction
4.1  Materials Connector bodies shall be made of glass-fibre-reinforced nylon or other mouldable insulating material of equal or superior properties. The contact parts shall be coated to ensure low deterioration and low electrical resistance.4.2  Terminals Terminals shall be in accordance with figure 3 and permanently attached to the cable ends before moulding, by soldering, brazing, welding or by other suitable method to provide a connection which will be mechanically and electrically secure. 4.3  Cables Current-carrying cables shall be 50 mm 2 , 70 mm 2 or 95 mm 2 wire size and shall conform with IEC 228 Class 5. Receptacle cables and plug cables shall be type 245 IEC 66 according to IEC 245-4. Particularly flexible stranding shall be used on the plug cables. All cables shall be of sufficient length and have the appropriate terminals to connect with appropriate points within or between the machines or to any auxiliary power source. All connecting cables shall be properly secured and protected within the machine. 4.4  Fuses All fuses shall meet the requirements of IEC 269-1. 4.5  Identification of cables Colour or number identification of cables shall conform with ISO 9247 and be arranged as shown in figures 1 and 2 of this International Standard, to provide continuity of identification throughout the connected assemblies.
5  Location of receptacle on machine
The receptacle shall be attached on the interior side of the machine with the terminal portion protruding outward through acceptance holes in the side of the machine (see figure 1) and located so that exposed portions of the receptacle will be protected from external damage by means of a lockable cover as shown in figure 4. Where safeguarding is a concern, the location may be inside an enclosed compartment. The location should also provide easy access for attaching the auxiliary starting cables, and should be as close as practical to the starter motor in the machine so as to require a minimum length of connecting cables. The machine manufacturer shall provide a label indicating the electrical system voltage at the receptacle.
