AS ISO 11862:2021 pdf free 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.

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, such as a battery cart, to the machine [see figure 2 b)]. The plug contains the female terminals [see figure 3 a)] and mates with the receptacle assembly in 3.1.
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.
