SIZE OF THE ELECTRICAL CABLES
Always use cables of a suitable cross-section. The minimum cross-sections are listed in the table below:

For system protection, the fuse must be installed in the positive wires (+) as close as possible to the battery. We recommend
using 15 A fuses for 12 V and 7.5 A fuses for 24 V. If using a main switch, it must be able to withstand a minimum current of 20
A. Avoid extra junctions in wiring to prevent voltage drops that can influence battery protection settings.
Note: ground connection can be used if necessary.
TROUBLESHOOTING
All work on electrical parts or electrical connections and the refrigerant circuit must be carried out by qualified and authorised
personnel.
Warning: Disconnect electrical power before performing any operations on electrical parts or on electrical connections.
Please also see the Display Errors Table at point 2.1.6.
DEFECT
The refrigerator does not
cool, the compressor will
not start.

POSSIBLE CAUSE
No electrical power. Battery
in poor conditions. Faulty
thermostat. Defective
electronic control unit.
There is insufficient voltage or
else a drop in voltage during
the attempt to start. The
protection device is activated.
The Batteries are drained.
Loss of refrigerant through
the evaporator or the tubing.
Tubing clogged.

INTERVENTION
Check to make sure that the electronic control unit is
receiving sufficient power and voltage; check the fuse.
Verify that the internal lighting is working and that the
compressor is receiving power. Check the cables, lugs and
connectors. Verify that the battery is charging properly.
Check the thermostat: Bridge T - C with a separate cable.
If the compressor will not start, its electronics are probably
defective. Replace. If the compressor starts up with the
bridge, the thermostat is defective. Replace the thermostat.
Check the cables and connections; remove any traces of
oxidation or corrosion. Charge the batteries, start the motor
or connect the battery charger.
Carry out a leak check and repair any leaks, drain and refill
the proper amount of R134a refrigerant. (This operation
must be carried out by a qualified technician.)
