•
The cables must have a section suited to the type of load and the positioning of said load within the vehicle.
•
The passage of cables in holes and on edges of various panels must be protected by cable glands (besides the corrugation).
•
The corrugated pipe must protect the whole cable completely and must be joined (with heat shrink sections or taping) to the
rubber caps on the terminals. In addition the corrugated pipe clamps (cut longitudinally) must not be in contact with the sharp
edge of the pipe.
•
All the terminals (+) for connecting the aforesaid cables and their lugs must be protected by rubber caps, (airtight for zones
exposed to the weather or with any stagnation of water).
•
The fastening of the lugs on the terminals (also negative) must be assured to avoid loosening, applying a tightening torque where
possible and fanning out the lugs in the case of multiple connections (preferably to be avoided).
It is always necessary to isolate the battery before doing any work on the electric system, disconnecting the power cables, first the
negative pole then the positive one.
Use fuses with the required capacity for their specific function. Never use fuses of higher capacity. Change them only after eliminating
the problem with keys and ancilliaries disconnected.
Restore the original conditions of the wiring (routing, guards, and binding, preventing the cable at all costs from coming into contact
with metal surfaces of the structure that may impair its integrity).
Precautions for operations on the frame
During work on the chassis frame, to safeguard the electrical system, disconnect the relevant components and the earth
connections, follow the guides given in points 2.1.1 and 2.3.4.
When required by the use of auxiliary equipment, protective diodes must be installed for any inductive current peaks.
The ground signal coming from the analogue sensors must only be wired to the special receiver; further ground connections could
falsify the output signal coming from these sensors.
The cable bundle for low intensity signal electronic components must be placed parallel to the reference plane, that is attached to
the chassis/cab structure, in order to reduce parasitic capacity to a minimum; distance the path of the additional cable bundle as
far as possible from the existing path.
Auxiliary systems must be connected to the system ground with the utmost care (see point 5.4.1); associated cabling must not run
alongside the electronic systems already on the vehicle in order to avoid electromagnetic interference.
The wiring of the electronic systems (length, conductor type, arrangement, clamping, connecting shield braids etc.) must follow the
original IVECO standards.
Carefully reset the original system after carrying out any work.
