SPECIAL INSTRUCTIONS FOR ELECTRONIC SUBSYSTEMS 5-27 E UROCARGO Euro 4/5 The electric supply of the appliances, if requiring a different voltage to that of the system, must be obtained via a suitable DC/DC 24-12V converter if not already contemplated. The supply cables must be as short as possible, avoiding any coils (twisting) and ob- serving the minimum distance from the reference surface. ! In case of installation of devices that can interact with other electronic systems suchas: Retarders,addi- tional heaters, power take-offs, air conditioners, automatic gearboxes, Telematics and speed limiters, contact IVECO in order to optimize the application.
NOTE For operations that could cause interference with the standard system, it is necessary to perform diagnostic checks in order to ensure correct assembly of the system. These checks can be made using the diagnostic ECUs [Electronic Control Units] on the vehicle or the IVECO service. IVECO reserves the right to have warranty on the vehicle elapse if any work not conforming to its directives is carried out. 5.8.3 Additional equipment The vehicle system is designed to supply the necessary power to the equipment provided, for each piece of which, within its respective function, the specific protection and the correct sizing of the cables are ensured.
The application of additional equipment must make provision for suitable protection and must not overload the vehicle’s system. The connection to ground of the added services must be made with a cable of suitable cross-section, as short as possible and made so as to allow movement of the added equipment in relation to the vehicle’s chassis frame. Needing batteries of greater capacity, for the demands of added loads, it is wise to request the option with uprated batteries and alternators.
In any case it is recommended not to exaggerate in increasing the capacity of the batteries over 20-30% of the maximum values supplied as an option by IVECO, so as not to damage any components of the system (e.g. starter motor). When higher capacities are necessary, use additional batteries, taking the necessary precautions for recharging, as indicated below. Additional batteries and alternators The installation of electric appliances with a high power input (e.g.
electric motors operated often or even more rarely for long periods and without using the vehicle’s engine, such as the tail lifts), or a large number of additional electrical appliances can require powers that the vehicle’s normal system is not able to deliver. In these cases additional batteries of suitable capacities must be used. Their insertion in the vehicle’s circuit must make provision for a separate recharging system (see Figure 5.13) integrated with that of the vehicle. In this case it is a good rule to use additional batteries of the same capacity as the ones originally mounted in order to recharge all the batteries correctly. Electrical system:
