PROTECTION AND SAFETY DEVICES 
All the vehicle supply lines were designed taking into account the most up-to-date directives in terms of 
safety and protection, especially to prevent fires. 
There are 2 types of protection: 
- active protection, aims to reduce the causes of faults "at source" 
- passive protection, aims to limit the effects of a fault as much as possible 
The first category includes a carefully designed wiring layout with wires positioned and carefully anchored 
on tracks that are repaired and protected if necessary. 
The cables connected to the alternator and the motor were modified for this reason by adding protective 
caps etc. A strengthened sheath was also introduced for some of the more exposed sections of wiring. 
The passive protection includes all interventions to reduce faults due to high current (overload, short cir
cuit). 
All system fuses were rated based on the nominal absorbtion of the loads activated at the same time, to 
ensure intervention in cases of a clear short circuit. 
The introduction of a box containing 4 maxifuses with other fuses connected on the outside means all 
the supplies can be protected except for the cable that connects the battery to the starter motor and the 
cable that connects the starter motor to the recharging alternator. These cables are therefore protected by a 
strengthened supplementary sheath.
