GENERAL WARNINGS REGARDING THE ELECTRICAL SYSTEM
NOTE
Do not use fast chargers to start up the engine. Start up must only be performed with either separate batteries or special
truck.
Incorrect polarisation of the power supply voltage for the electronic control units (e.g. erroneous battery polarisation)
may damage the components irreversibly.
Disconnect the batteries from the system before recharging them by means of an external unit.
On connecting, only screw connector (temperature sensors, pressure sensors, etc.) nuts to the prescribed tightening
torque.
Isolate the circuit prior to disconnecting the junction connector from an electronic control unit.
Do not directly supply current to components served by electronic control units with rated vehicle voltage.
The cables must be routed in such a way as to be parallel to the reference plane, as close as possible to the chassis/body.
Upon completing work on the electrical circuit, restore the electrical connectors and wiring as originally provided.
When having to operate on the electrical/electronic circuit, disconnect the batteries from the circuit, disconnecting the
chassis earth cable first of all from the negative terminal of the battery.
Before connecting the batteries to the system make sure the latter is well insulated.
Disconnect the external recharging apparatus from the public utility network before removing the apparatus pins from
the battery terminals.
Do not cause sparks to verify the presence of voltage in a circuit.
Do not use a test bulb to check the continuity of a circuit. Only use the appropriate testing devices.
Make sure that the wirings of electronic devices (length, type of cable, location, strapping, connection of screen braiding,
grounding, etc.) conform with the FPT system and that they are carefully restored after repair or maintenance work.
Measurements on the ECUs, jack connections and electrical connections of components must be done only on regular
test lines, with special jacks and jack bushings. Never use improvised equipment like metal wires, screwdrivers, pins or
similar. This may not only cause short circuits, but also damage the jack connectors, resulting in poor contact.
The connectors are shown from cable side. Connector views contained in the manual are representative of cable side.
