7、rights reserved iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a s
8、ubject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission
9、(IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical comm
10、ittees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not
11、be held responsible for identifying any or all such patent rights. ISO 17612 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 4, Tr a c t o r s.ISO 17612:2004(E) iv ISO 2004 All rights reserved Introduction This International Standar
12、d specifies an electrical connector for the transmission of auxiliary power within the operator station of enclosed agricultural machines. The specification thus established will allow manufacturers to provide both individual and multiple outlets in the cab. Typical applications include monitors, li
13、ght-duty controllers, remote operating devices and miscellaneous off-the-shelf items. Only the application dimensions and electrical characteristics are covered. Other electrical transmission connectors for agricultural tractors and machinery are specified in ISO/TR 12369. For this and other Interna
14、tional Standards dealing with connectors for electrical power transmission from tractor to implement or other means, see the Bibliography.INTERNATIONAL STANDARD ISO 17612:2004(E) ISO 2004 All rights reserved 1 Tractors and machinery for agriculture and forestry Auxiliary- power-transmission connecto
15、r for the operator station 1S c o p e This International Standard specifies the essential interface dimensions of a connector and its plug for the transmission of electrical power within the enclosed operator station of agricultural tractors and machinery. The device is intended to be used as a non-
16、environmentally sealed, convenient source for power auxiliary devices, providing a means for the operator to obtain electrical power without altering the tractor/machine electrical wiring harness.
