The high-current power supply (red cable +, white cable -) provides current to the 12V
heating element of the cooling system. This connection point may supply 12V only when the
engine of the car or motor home is running.
E Models (Figure 1): the low-current power supply (purple cable +, black cable -) provides
a continues current of 12V for ignition of the burner and the light in the refrigerator. The 12V
supply is obtained via the connection to the car or motor home battery or via the 230V AC
à12V DC transformer.
- Make sure the power point is in a position that is easy to reach.
- Minimize voltage drops by thoroughly fixing the wires.
- Position the 12Vpower lead so that it cannot come into contact with hot or sharp parts.
- In connection with voltage drops in high-power supply, the diameter of the lead
depends on the lead length: Leads longer than 6 m à for optimum performance the
lead diameter should be 6 mm² (with a minimum of 4 mm²).
- The high -current power supply must be fitted with a 12 A fuse, the low current
supply must be fitted with a 1 A fuse.
7.3 Connecting to a DC power supply in vehicles with a separate D
signal
The high current connection (HC, red wire +, white wire -) provides current to the DC
heater of The cooling system. This connection should be connected to a continues DC supply.
Connect the red and the white wire directly without any breakers (e.g.contact) to the vehicle
starter battery. This connection is protected on the power board with a 20A fuse.
The low current connection (LC, purple wire +, black wire -) provides a continues current of
DC for the power board of the refrigerator. This DC supply is obtained via the connection to
the auxilary battery or via the 230V AC àDC transformer. This connection is protected on
the power board with a 2A fuse.
The D+ connection (orange wire +) ensures the DC heater can not be switched on (manual or
automatic) when the engine of the vehicle is not running.
Connect the D+ connection to a DC connection point that shows that the vehicle's engine is
running (engine running: DC, engine not running: no voltage)
This connection is only used as a signal cable.
- Position the connecting point so that it is easy to reach.
- Make sure that all connections are properly fastened to minimize voltage drops.
- Use wires with a diameter of 10 mm² (wi t h a minimum of 6 mm²) to ensure optimum
performance of the refrigerator.
- Position the DC power lead in such a way that it cannot come into contact with hot or
sharp parts.
- In connection with voltage drops in high power supply, the diameter of the leads
depends of the lead length: Leads longer than 6 m à for optimum performance the
lead diameter should be 6 mm² (with a minimum of 4 mm²).
- In conformity with EN 1648-1/2 the respective negative and positive wires of the DC
connections high current and low current can not be connected together.
