Appendix IV
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 ensure adequate protection from unwanted electrical
noise. This can be veri ed by measuring the resistance between the vehicle chassis/frame and the other
trailer component, then con rming that the resistance is less than 10 Ohm (< 10 Ω).
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 connec-
tions from contamination and humidity.
Always connect the grounding electrode directly with the metal next to the welding position when
welding, to prevent magnetic elds and current ow via the cable or components.
Make sure that grounding connections are robust by removing paint or rust at the connection points.
Prevent heat in uences from the welding activity on devices and cabling when welding.
Note during electrostatic painting the trailer frame or bogie:
Disconnect all cable connections to devices and components and protect the plug-ins and connec-
tions from contamination and humidity.
