7.1 General precautions for cable position
• Securing the cables:
- secure the harness so that it does not interfere with moving parts;
- route the harnesses in such a way that they cannot come into contact with moving parts.
• Routing the cables to protect against water infiltrations:
- branches in the cable runs must ALWAYS be oriented downwards (Fig. 17a).
Fig. 17a Fig. 17b
• Fitting the cables to the connection points:
- do not force the connectors by pushing too hard or bending them: the contacts can be damaged and computer operation compromised.
Use ONLY the cables and accessories indicated in the catalogue, having technical features suitable for the use to be made of
them.
7.2 Power supply connection
Inside the package (component 12 , Fig. 1) you will find the power connector required for the connection to the machine’s battery;
Fig. 18c shows the drilling template for installing the power connector.
Connect the power connector to the battery wires using two 6 mm faston connectors, as shown in figs. 18a and 18b.
Use the cable provided in the package (component
3
, Fig. 1) to connect the computer to its power supply.

WARNING:
To avoid short circuits, do not connect the power cables to battery before the installation is completed.
Before powering up the computer and control unit, make sure the battery voltage is as specified (12 Vdc).
BRAVO 400 is powered directly from the battery (12 Vdc): it must ALWAYS be switched on from the computer; when finished, switch the computer off
manually using the suitable key on the control panel.
Keeping BRAVO 400 on for long periods of time when the machine is off may run down the tractor battery: be sure to switch off
the computer if the machine is to be left unused with the engine off for some time.
Connect the power source as shown in Fig. 19:
the computer must be connected directly to the machine's battery. DO NOT connect the computer
to key-operated switch (15/54).

WARNING:
• The power circuit shall ALWAYS be protected by a 10 A fuse
like the ones for automotive applications.
• All cables connected to the battery shall have a minimum cross-
section of 2.5 sq. mm.
To avoid short-circuits, connect the power cable connector only
after completing installation.
• Use cables with suitable terminals ensuring correct connection
of all wires.
