CAUTION:
To avoid short-circuits, connect the power cables to the battery only after comple-
ting installation. Before powering the monitor and system on, make sure that battery
voltage is correct (12 Vdc).
Alfa 310S is directly powered by the farming machine battery (12 Vdc): ALWAYS switch monitor
on through the relevant procedure; after use, remember to manually switch monitor off through the
relevant push-button on control panel.
Leaving Alfa 310S on for too long while farming machine is stopped could drain the
tractor's battery. If the machine stays with engine off for a long time, make sure you
turned the monitor off.
Power supply shall be connected as shown in Fig. 11.

motive applications.
• All cables connected to the battery shall have a minimum cross-section of 1,5 mm
2
.
• To avoid short-circuits, connect the power cable connector only after completing
