Load-Dump Protection for Transportation

Vehicles

This appendix describes load-dump protection that is required for access point/bridge operation in some transportation vehicles.

Load-Dump Protection

The access point/bridge can be installed in vehicles such as automobiles, trucks, and buses. Electronic equipment in vehicle environments can be subjected to high-energy voltage transients where the vehicle battery is accidentally disconnected from the alternator charging circuit. In the Society of Automotive Engineers (SAE) standards SAE J1455 and SAE J1211, this voltage transient is referred to as a load-dump transient, where the loading of the battery is dumped or removed from the alternator charging circuits. The access point/bridge does not contain built-in load-dump protection.

Note The power injector LR2T must be used in vehicles providing DC power to the power injector.

Some vehicles contain centralized electronics that are designed to suppress the load-dump transient and prevent equipment damage. To protect the bridge in vehicles without built-in load-dump suppression, you must install an external load-dump protection device, such as the IFM-efector EC2015 for nominal 12-VDC operation or the EC2016 for nominal 24-VDC operation.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030

Warning A readily accessible two-poled disconnect device must be incorporated in the fixed wiring. Statement 1022
