▶

Interventions on the electrical system (e.g. removal of cables, addition of circuits, replacement

of equipment or fuses etc.) carried out in a manner which is not compliant with IVECO's instruc-

tions or carried out by non qualified personnel, can cause severe damage to on-board systems

(control units, wiring, sensors etc.), affect driving safety and good operation of the vehicle and

cause serious damage to the vehicle (e.g. short circuits with the possibility of fire risk or destruc-

tion) which is not covered by warranty.

Before removing any electrical/electronic equipment, disconnect the ground cable from the battery negative pole and then the

positive cable.
To prevent damage to the vehicle's electrical system, follow the instructions of the cable manufacturer.

●

The cables must have suitable sectioning for the type of load and the position of the load in the vehicle.

●

The power cables (+ direct) must be:

■

individually intubated in conduits (of suitable diameter) and not together with other different cables for signal and negat-

ive;

■

placed at least 100 mm (reference value = 150 mm) from high heat sources (turbine, engine, exhaust manifold, etc.);

■

placed at least 50 mm from containers of chemical agents (batteries, etc.);

■

placed at least 50 mm from moving parts.

●

The path of the cables must be defined with brackets and clamps dedicated and reconciled, to avoid hanging parts and to be

able to restore the same installation after repairs or interventions.

●

The cables must have a suitable sectioning for the type of load and the position of the load in the vehicle.

●

The passage of cables through holes and on the edges of metal sheets must be protected by cable gaskets in addition to the

corrugated tube
It is not possible to specially drill the chassis to allow the cables path.

●

The corrugated tubing must completely protect the entire cable and be connected (with heat shrinking or taping) to the rub-

ber caps on the terminals.

●

All the positive terminals and cable terminals must be protected by rubber caps (for hermetic in areas exposed to weathering

or with possible stagnation of water).

Use fuses with the prescribed capacity for the specific function, and do not under any circumstances use higher capacity fuses.
Restore the original condition of the wiring (paths, protections, strips) completely avoiding the cable to come in contact with metal-

lic surfaces of the structure that can impact the 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 "precautions (

➠

Page 14)".

In cases where the application of additional devices requires it, the installation of protective diodes for inductive current spikes must

be provided for.
The ground signal from the analogue sensors must be wired exclusively on the specific receiver; additional ground connections may

distort the output signal from this sensor.
The cable bundles for low signal intensity electronic components must be arranged parallel to the metal plane of reference, that

is 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 Chapter 5.4 - Paragraph "Ground

points (

➠

Page 16)"); 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, dislocation, strips, cable shielding connection, etc..) com-

ply with the original IVECO provision.
Carefully restore the original system after any operations.
