information
Observe all required regulations and instructions:
– Read this publication thoroughly.
Adhere to all instructions, information and safety information to prevent injury to
persons and damage to property.
WABCO will only guarantee the security, reliability and performance of their
products and systems if all information in this publication is adhered to.
– Make sure to follow the specifications and instructions of the vehicle manufac-
turer.
– Maintain all accident regulations of the business as well as regional and na-
tional regulations.
Make provisions for a safe work environment:
Only trained and qualified technicians are to perform any work on the vehicle.
– Use personal protective equipment if required (protective goggles, respiratory
protection, ear protectors, etc.).
Pedal actuations can lead to severe injuries if persons are in the vicinity of the ve-
hicle. Make sure that pedals cannot be actuated as follows:
– Switch the transmission to ‘neutral’ and actuate the park brake.
– Secure the vehicle against rolling with chocks.
– Fasten a visible note to the steering wheel indicating the work is being per-
formed on the vehicle and that the pedals are not to be actuated.
Avoid electrostatic 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.
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 between metal
parts in the towing vehicle and the coupled trailer via the coupling (king pin, fifth
wheel, claws with pins), even without a cable being connected.
– Use electrically conductive bolted connections when fastening the ECUs to the
vehicle frame.
– Run the cable in metallic casing if at all possible (e. g. inside the U-beam) or
behind metallic and grounded protective plating, to minimise the influence of
electro-magnetic fields.
– Avoid the use of plastic materials if they can cause electrostatic charging.
– For electrostatic painting, connect the ground line of the ISO 7638 plug connec-
tion (pin 4) to the paint ground (vehicle chassis).
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.
