Electrical System: Modifications and Drawing-Off Power

Additional Circuits
These must be separated and protected by a fuse from the vehicle’s main circuit.
The cables utilised must be of a size that is suitable for the relative functions and must be well insulated. They must also be suitable
protected in sheaths (not PVC) or routed though flexible conduits in the case of a plurality of functions (we recommended the use
of polyamide type 6 plastic for flexible conduits) and they must be correctly installed in a place where they are protected from impact
and heat sources. Take care to avoid any chaffing with other components, particularly with live edges of the bodywork. The transit
of these cables through structural components (cross members, profiles, etc.) must be executed using suitable cable glands or protec-
tions; firstly the cables must be secured separately with insulated cable clamps (e.g. made of nylon) at adequate intervals (approx.
200 mm).
In the case of external panels use a suitable sealant on both the cable and on the panel, to avoid the risk of infiltration of water,
dust, or fumes.
Establish suitable distance between electrical wiring harnesses and other components as follows:
-
10 mm from static components;
-
50 mm from moving components (minimum distance = 20 mm);
-
150 mm from components that generate heat (e.g. engine exhaust).
Wherever possible it is good practice to follow a different cable route for signal cables interfering at high absorbed intensity (e.g.
electric motors, solenoid valves) and signals that are susceptible to low absorbed intensities such as sensors, maintaining in any event
a position as close as possible to the metal structure of the vehicle in both cases.
Plug and terminal connections must be protected, resistant to weathering, and executed using components of the same type as
those utilised originally on the vehicle.
Use cables and fuses with the characteristics shown in the following table in accordance with the current draw:

1)
For uses of more than 30 seconds.
2)
Depending on the position and hence the temperature that may be reached in the housing, choose fuses that can be loaded to up to 70% - 80% of their maximum
capacity.
!
The fuse must be connected as close as possible to the current take-off point.
Precautions
-
Incorrect installation of electrical accessories may affect occupant safety and cause severe damage to the vehicle.Contact IVECO
if you have any questions.
-
Avoid coupling with signal transmission cables (e.g. ABS), for which a preferential path has been defined for electromagnetic
requirements (EMI).
It should be noted that when grouping several cables together, in order to compensate for the lower heat dispersal capacity
current intensity must be reduced with respect to the nominal value of a single cable.
-
In vehicles subject to frequent engine starts, in the presence of power draws with limited engine running times (e.g. vehicles with
refrigerated bodies) periodic battery charges are required to maintain optimal efficiency.
