Bonding and screening

Negative leads connected to a system bonded point must be both as short and possible and “star“-connected to each other, trying
then to have their centering tidily and properly made (Figure 1, re. M).

Further, following warnings are to be compulsorily observed for electronic components:

-

Electronic central units must be connected to system bonding when they are provided with a metallic shell.

-

Electronic central units negative cables must be connected both to a system bonding point such as the dashboard opening
bonding (avoiding “serial“ or “chain“ connections), and to battery negative terminal.

-

Analog bonding (sensors), although not connected to battery negative system/terminal bonding, must have optimal isolation.
Consequently, particularly considered must be parasitic resistances in lugs: oxidising, clinching defects, etc.

-

Screened circuits braiding must only electrically contact the end towards the central unit entered by the signal (Figure 2).

-

If junction connectors are present, unscreened section d, near them, must be as short as possible (Figure 2).

-

Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to chassis/body structure.

OPTIONAL ELECTRICAL AND MECHANICAL PARTS INSTALLATIONS

Assemblies shall be modified and equipped with additions - and their accessories shall be fitted - in accordance with the assembling
directives issued by IVECO Motors.
It is reminded that, especially about the electric system, several electric sockets are provided for as series (or optional) sockets in
order to simplify and normalise the electrical intervention that is care of preparation personnel.

It is absolutely forbidden to make modifications or connections to electric central units wiring harnesses; in particular,
the data interconnection line between central units (CAN line) is to be considered inviolable.
