F3: 10A fuse connected directly to battery to power heater/boiler group.
F4: 10A fuse connected directly to water pump switch.
F5: 5A fuse connected to external light switch.
F6: 3A fuse connected directly to battery to power ignition(fridge,stove,etc.).
F7: 20A fuse connected directly to battery to power AUX_2.
F8: 20A fuse connnected directly to battery to power AUX_1.
F9: 30A fuse connected to fridge switch to power fridge.

Attention: If replacing faulty fuses, observe the amperage required.
OPERATION:
Utilities activated by control panel:
With the panel off all outputs are disabled through the B1 and B2 security box master switches.
With the panel on the security box B2 master switch is activated.
The B2 security box switch is not activated if the service battery voltage is lower than 6 Volt
(also if there is 230 Volt mains) .
The external light, the pump and the light outputs are activated directly by the relative push buttons
on the control panel.
Utilities activated by D+:
The outputs JP4, JP5 and JP6 are active only if the engine is running. With the engine running and
vehicle battery voltage greater than 13.3 Volt for over 15secs. the fridge output and the two master
relays for security boxes B1 and B2 are activated (in this way the batteries are coupled).
The fridge output and coupling are deactivated immediately if voltage drops below 12 Volt or the
engine is turned off.
Coupling recharges the service battery by means of an alternator. The fridge relay allows the trivalent
fridge to be continuosly powered at 12V when the engine is running.
The external light goes off automatically with the engine running.
