ELECTRIC SYSTEM KOSMO
Truma system temperature sensor
Sensor usually installed next to the control panel,
required for the operation of the Truma heating
system.
USB sockets
There are USB sockets in the living quarters that can
be used to charge devices such as smartphones. To
supply current to the USB sockets, activate on the
control panel the inside lights button (all the models
except for Compact 5 and Compact 9) or the on/off
main switch (Compact 5 and Compact 9).
Awning light
An awning light is fitted on the right-hand wall of the
vehicle. It can be turned on (only when the engine is
off) by means of the switch located on the control
panel.
8.5 Booster
An additional component (booster) is fitted on the
vehicles to optimise auxiliary battery charging while
driving. The booster is located near the 12 V distri-
bution control unit.
Charging profile
According to the type of auxiliary battery installed
in the vehicle, the booster must be set to the most
suitable charging profile. The charging profile is deter-
mined by the type of connection of the orange cable:
• Leave the orange cable disconnected to select a
maximum voltage of 14.6 V (Profile A).
• Connect the orange cable with the General Earth
to select a maximum voltage of 15.0 V (Profile B).
• Connect the orange cable with the red cable
(battery positive) to select a maximum voltage of
15.3 V (Profile C).
• Connect the orange cable with the green cable to
select the Li profile (Lithium profile).
The actions described must be performed exclu-
sively by specialised personnel. Always contact a
Laika authorised workshop.
WARNING
Check the technical specifications provided by
the auxiliary battery manufacturer to ensure that
the maximum voltage of the selected profile does
not exceed the maximum charging voltage recom-
mended by the manufacturer. Choose another
charging profile if the maximum voltage is too high
for the type of battery installed.
