15.1 Vehicle Electrical Grounding Guidelines
Ensure that the vehicle includes a correct common chassis ground point. A common chassis ground point
connects the trailer frame/chassis to the ground pin of the J560 seven-way connector and will help protect
the vehicle electrical system from unwanted electrical noise.
contact at the ground point. If a common chassis ground point is not present, ZF recommends adding one.
Do not add more than one common chassis ground point (connecting the J560 ground pin to the
chassis) to help avoid potential ground shifts within the vehicle electrical system.
Additionally, all standard trailer components, such as axles, should also be electrically connected to the
common chassis ground. If the axles are not correctly grounded to the chassis, a ground strap electrically
connecting the axle to the chassis may be added to provide protection from unwanted electrical noise.
For more details concerning correct vehicle grounding, reference SAE standard J1908.
Note during welding work on the trailer:
Disconnect power to the trailer.
Disconnect all cable connections to devices and components and protect the plug-ins and connections
from contamination and humidity.
Always connect the grounding electrode directly with the metal next to the welding position when
Make sure that grounding connections are robust by removing paint or rust at the connection points.
Note during electrostatic painting the trailer frame or bogie:
Disconnect all cable connections to devices and components and protect the plug-ins and connections
from contamination and humidity.
