●
The fastening of the cable housings to the terminals (also negative), should be secured to prevent unscrewing, applying a
torque where possible and placing them "radially" in the case of multiple connections (to be avoided if possible).
▶
Use only fuses with the features prescribed for the specific function. NEVER USE FUSES WITH
A CAPACITY HIGHER THAN THE PRESCRIBED. Replace using only keys and disconnected
users.
When the operations have been completed, restore the original conditions of the wiring (paths, protections, strips), making sure
that the cables are not in contact with metallic surfaces which could affect their integrity.
Precautions for work on the chassis
For work on the chassis, to protect the electrical system, its equipment and ground connections, respect the precautions shown in
Chapter 2.1 - Paragraph "Special Precautions" (
➠
Page 5) and Chapter 2.3 - Paragraph "Welding" (
➠
Page 8).
If required by the application of additional devices, diodes must be fitted to protect against any inductive current peaks.
The ground signal from the analogue sensors must only be wired on the specific receiver; additional ground connections may dis-
tort the output signal from this sensor.
The cable bundles for low signal intensity electronic components must be arranged parallel to the reference metal plane, namely
adherent to the chassis / cab structure, in order to minimise parasitic capacities; space the path of the cable bundle added to the
existing one as much as possible.
The added systems must be connected to the ground of the system with the utmost care (see Paragraph "Ground Points"
(
➠
Page 36)); the related wiring harnesses should not be coupled to the electronic circuits that already exist on the vehicle in
order to avoid electromagnetic interference.
Ensure that the wiring of the electronic devices (length, type of conductor, position, strips, cable shielding connection, etc.) comply
with indications provided by IVECO.
Carefully restore the original system after any operations.
Ground points
The original ground connections of the vehicle should never be altered; in cases where these connections must be moved or new
ground points added, use the holes present on the chassis to the extent possible, taking care to:
●
mechanically remove - either by filing and/or with a suitable chemical based solution - the paint on both the chassis and ter-
minal side, thus creating a contact surface free of indentations and edges;
●
paint the area between the terminal and metal surface with a suitable high conductivity paint
●
connect to ground within 5 minutes after application of the paint.
As regards the signal related ground connections (e.g. sensors or low-absorption devices), do not use the standardized points Un-
der no circumstances use standardized points for engine ground connection and chassis ground connection.
Additional signal grounds must be positioned at different points from the power ground.
