GENERAL WARNINGS ON THE ELECTRIC SYSTEM ! If an intervention has to be made on the electric/electronic system, disconnect batteries from the system; in this case, always disconnect, as a first one, the chassis bonding cable from batteries negative terminal. Before connecting the batteries to the system, make sure that the system is well isolated. Disconnect the external recharging apparatus from the public utility network before taking apparatus pins off battery terminals. Do not cause sparks to be generated in checking if the circuit is energised. Do not use a test lamp in checking circuit continuity, but only use proper control apparatuses.
Make sure that the electronic devices wiring harnesses (length, lead type, location, strapping, connection to screening braiding, bonding, etc.) comply with IVECO system and are carefully recovered after repair or maintenance interventions. Measurements in drive electronic central units, plugged connections and electric connections to components can only be made on proper testing lines with special plugs and plug bushes. Never use improper means like wires, screwdrivers, clips and the like in order to avoid the danger of causing a short circuit, as well as of damaging plugged connections, which would later cause contact problems. To start up the engine, do not use fast chargers.
Start up must only be performed with either separate batteries or special truck. A wrong polarisation of supply voltage in drive electronic central units (for instance, a wrong polarisation of batteries) can cause them to be destroyed. Disconnect the batteries from the system during their recharging with an external apparatus. On connecting, only screw up connector (temperature sensors, pressure sensors etc.) nuts at prescribed tightening torque. Before disconnecting the junction connector from an electronic central unit, isolate the system. Do not directly supply electronic central units servo components at nominal vehicle voltage.
Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to chassis/body structure. Once the intervention on the electric system has been completed, recover connectors and wiring harnesses according to original arrangement. Key memorisation procedures are influenced by electromagnetic jamming (mobile phones, etc.). Therefore, during key memorisation: 1 Pay attention that jamming sources are not present in the cab or near the keys. 2. Keys not insered in the panel must be at least 1 meter away. NOTE Connectors present must be seen from cable side. Connectors views contained in the manual arerepresentative ofcable side.
