5-24 SPECIAL INSTRUCTIONS FOR ELECTRONIC SUBSYSTEMS E UROCARGO Euro 4/5 - for the cable passage use the existing holes; if necessary and essential make an additional hole; take the precautions to preserve the bodywork (rustproofing, liner, etc..); - assure a good connection with the structure of the vehicle (ground), both of the base of the antenna and of the containers of the appliances, to achieve the maximum transfer of power. The typical installation positions of transceiver equipment are those of the dashboard-gearbox or roof assembly zone - driver side (see Figure 5.12).
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. Figure 5.10 98915 1. Antenna support - 2.
