16、ht commercial vehicles with a nominal voltage of 36 V. This standard specifies the position, details of design and dimensions of a system of battery terminals. Starter batteries with 36 V nominal voltage may have the same dimensions and means for fixation as 6 V or 12 V batteries. This can be either
17、 intentional or unintentional. Therefore, the compatibility of batteries with 36 V nominal voltage down to electric power nets with 6 V or 12 V nominal voltage should be prevented. Such design of a 36 V termination and contacting system must prevent the case to be connected to a 6 V or 12 V power ne
18、t in order to avoid serious damage in the 6 V or 12 V power net. For the same reason the design of the battery terminals must prevent that standard commercial jumper-cables may be contacted to the 36 V battery terminals if the battery is installed in the vehicle or not. A commercial application of t
19、his standard must expressively be agreed upon as the final standard may differ from the present draft. 2 Normative references The following referenced documents are indispensable for the application of this document.

22、the purposes of this document, the terms and definitions of the International Electrotechnical Vocabulary (IEC 60050-482) are applicable. 4 Design, dimensions and resignations 4.1 General All measures are indicated in millimetres. Mechanical tensions must be kept away from the bushings of the batter
23、y. A free space at the side and behind each terminal is required for electric/electronic devices. Further on the free space may provide the possibility to support the cables mechanically. The system of battery terminals must prevent reversed polarity in order to avoid damages in the 36 V power net.

25、positive and negative battery terminals and there position to the outer contour of the battery cover. The position and dimension of the battery terminals including the free space besides the terminals are identical for the battery dimension LN3-36V through LN6-36V. As well Figure 1 shows the positio
26、n of the marking of polarity and the device for the rotatable touch-prevention.

T
29、he contact may be positioned and rotated in the area of the niche walls of the terminal by an angle of more than 225. NOTE The surface of the tinned sleeve needs to be specified later. In the upper section the sleeve has a groove around. This groove may be used for additional mechanical fixation of
30、the electrical contact. The free portion of the lead-cone can be used by the battery manufacturer for the formation. This lead-cone is covered by means of a plastic cap (4.2.5) before delivering the battery. 4.2.4 Clips for the rotatable touch protection The battery lid surface includes six clips fo
31、r touch protection centrically around each terminal. These clips have grooves at the inside to hold the rotatable touch protection. Five of these clips have also grooves at the outside (at the sixth groove this is not realizable because of manufacturing process reasons). These grooves may be used al
32、ternatively for the mechanical fixation of the electric contact if necessary. NOTE The outside groves may be cancelled, if they are not needed. 4.2.5 Plastic cap for terminal protection The cap for terminal protection according to Figure 3 prevents short circuits between the two polarities. At the s
33、ame time the cap for terminal protection together with the touch protection (4.2.6) prevents to use standard jumper-cables. The plastic cap is mounted by the manufacturer and remains unchanged on the battery during the battery live. The cap clips into the upper contour of the contacting sleeve and c
34、loses flush with the sleeve. For contacting the electrical contacting clamp is pushed over the cap. 4.2.6 Rotatable touch protection The battery terminal is covered in its full height by a continuously rotating touch protection device (Figure 4). This touch protection device is a plastic cylinder an
35、d is permanently connected to the battery cover with its clips. The slot in the cylinders is used for intrusion and positioning of the battery cables. The battery terminals and the touch protection have the same dimensions for both polarities. In order to achieve prevention of reversed polarity the
36、touch protection features differently positioned codes. 4.2.7 Free space behind the terminal Behind respectively at the side of the terminal the battery cover features a rectangular free space of minimum area of 50 mm x 50 mm. This free space may be used for components like electronic parts or distr
37、ibutors. Furthermore, the free space may be used to keep away mechanical tensions of the battery cable from the terminal bushing. 4.2.8 Marking of polarity For the marking of the polarity polarity signs are moulded into the battery cover. In addition the caps for terminal protection are marked in di
38、fferent colours.
