for connection to trailers using a special connector conforming to DIN Standard 72570 configured for 12 volt operation or ISO/DIN 7638:1996 or 2003 configured for 12 or 24 volt operation. If configured for 24 volt operation, the voltage must be marked on the plug and a warning label must be provided in the cabin to warn the driver. The power supply must provide DC current having a nominal voltage level of 12 volts or 24 volts.

       1.3.2     The connector must be wired to have the following functions:

       1.3.2.1 For 12 volt operation
        Pin 1  +ve high current trailer solenoid valve supply, 20 amps minimum continuous rated capacity 30 amps maximum capacity
        Pin 2  +ve low current trailer electronic unit supply, 4 amps minimum rated capacity
        Pin 3  -ve low current trailer electronic unit supply, 6 amps minimum rated capacity
        Pin 4 -ve high current trailer solenoid valve supply, 20 amps minimum continuous rated capacity 30 amps maximum capacity
        Pin 5 trailer 'Antilock System' failure, switched to -ve (eg pin 3 or pin 4) upon fault detection, 2 amps minimum rated capacity.

       1.3.2.2 For 24 volt operation
       Pin 1  +ve high current trailer solenoid valve supply, 10 amps minimum continuous rated capacity 15 amps maximum capacity
       Pin 2  +ve low current trailer electronic unit supply, 2 amps minimum rated capacity
       Pin 3  -ve low current trailer electronic unit supply, 3 amps minimum rated capacity
       Pin 4 -ve high current trailer solenoid valve supply, 10 amps minimum continuous rated capacity 15 amps maximum capacity
       Pin 5 trailer 'Antilock System' failure, switched to -ve (eg pin 3 or pin 4) upon fault detection, 1 amp minimum rated capacity.

       1.3.3     Either the optical warning lamp specified in clause 1.2.1 of this APPENDIX or an additional yellow optical warning signal (appropriately labelled) must light up whenever Pin 5 of the connector specified in clause 1.3.2 of this APPENDIX is connected to ground or a -ve connector.
