Safety information
1.1
Avoiding electro-static charge and uncontrolled discharging (ESD)
Note during
construction and
building the vehicle:
– Prevent potential differences between components (e. g. axles) and the vehicle
frame (Chassis).
Make sure that the resistance between metallic parts of the components to the
vehicle frame is lower than 10 Ohm (< 10 Ohm).
Connect moving or insulated vehicle parts such as axles electrically conductive
with the frame.
– Prevent potential differences between the towing vehicle and the trailer.
Make sure that an electrically conductive connection is made via the coupling
(king pin, fifth wheel, claws with pins), even with no cable connection.
– Use electrically conductive bolted connections when fastening the ECUs to the
vehicle frame.
– Use only cable conforming to WABCO specifications or WABCO original cable.
– Run the cable in metallic casing if at all possible (e. g. inside the U-beam) or
behind metallic and grounded protective plating, to minimize the influence of
electro-magnetic fields.
– Avoid the use of plastic materials if they can cause electrostatic charging.
Note during repair and
welding work on the
vehicle:
– Disconnect the battery - if installed in the vehicle.
– Disconnect 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 weld-
ing position when welding, to prevent magnetic fields and current flow via the
cable or components.
Make sure that current is well conducted by removing paint or rust.
– Prevent heat influences on devices and cabling when welding.
