5-28 SPECIAL INSTRUCTIONS FOR ELECTRONIC SUBSYSTEMS E UROCARGO Euro 4/5 Figure 5.13 Installation of supplementary batteries 117409 1. Standard batteries - 2. Supplementary batteries - 3. Alternator with incorporated regulator - 4. Starter motor - 5. Ignition key - 6. Contactors - 7. Front Frame Computer - 8. Instrument Cluster - 9. Body Computer The installation of additional batteries requires checking the ability of the alternator to do the recharging. If it is necessary you must use an alternator of greater power or another additional one; in this case make the connection as indicated in Figure 5.14.
By using electric motors that are controlled only with the vehicle engine running, instead of the additional batteries, it can be enough to use a more powerful alternator or an additional alternator. These alternators will have to be of the type with Zener diode rectifiers, so as to avoid the possibility of damage to the installed electric/electronic equipment due to accidental disconnection of the batteries.
