General information
The vehicles are designed to operate normally with a 12 V electrical system.
The chassis represents the ground (it acts as a power return conductor between the components located on it and the
batteries/alternator energy source) and the negative pole for the batteries and the components is connected to it, therefore an
isolated return is not provided.
The installation of auxiliary equipment or additional circuits must take account of the instructions given below and, according to the
complexity of the operation, suitable documentation (e.g. electrical diagram) must be provided to accompany that for the vehicle.
The use of cables and connections with colours identical to those used on the original vehicle makes the installation more accurate
and facilitates any repair work.
For efficient and correct use of the electrical system, specific connection points have been provided for auxiliary systems. This
condition is necessary to rule out any adaptions of the basic design in order to ensure operational integrity and thus maintenance
of the vehicle warranty.
For more detailed information on the vehicle electrical system, refer to the special workshop manual,
printed 603.95.161 (Daily MY 2012).
This manual is available at the Service network and can be requested from the relevant Departments
of the IVECO Sales Organisation.
NOTE
Precautions for operations on the system
!
Work on the system (e.g. removing wiring harness, making additional circuits, replacing equipment,
changing fuses, etc.) that is not done in conformity with IVECO instructions or is carried out by
unskilled personnel can severely damage the systems (control units, wiring, sensors, etc.), jeopardizing
safety and operation of the vehicle besides causing significant damage (e.g. short-circuiting with the risk
of fire and destruction of the vehicle) that is not covered by warranty.
Before removing any electrical and/or electronic components, disconnect the ground cable from the negative terminal of the battery.
To avoid damaging the vehicle’s electrical system, carefully follow the cable manufacturer’s instructions.
The cables must have a section suited to the type of load and the positioning of said load within the vehicle;
•
The power cables (+ direct) must:
-
be inserted individually in corrugated sheaths (with suitable diameter) and not together with others with different signals and
negative cables;
- be positioned at a distance of at least 100 mm (reference value = 150 mm) from very hot parts (engine turbine, exhaust
manifold, etc.);
- be positioned at least 50 mm from containers of chemical agents (batteries, etc.);
- be positioned at least 50 mm from moving parts.
•
The route of the cables must be defined as much as possible with dedicated brackets and clamps and moved closer, to avoid
hanging parts and provide the possibility (and obligation) to rebuild the same installation in the case of repairs or outfits.
