AS ISO 11862:2021 Earth-moving machinery — Auxiliary starting aid electrical connector
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.
4.5  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.
