- 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 on ly when the engine of the
car or motor home is running.
-
The low-current power supply (purple cable
+
, black cable
-
) provides a continuous current of
12v for ignition of the burner and the light in the refrigerator. The 12v supply is obtained via the
con nection to the car or motor home battery or via the 230v AC
à
12v 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 12v power 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 15 A fuse, the low -current power
supply must be fitted with a 1 A fuse.
7.3 Connecting to a DC power supply (12 V) for all S ES model s (see figu re 1)
The description below applies to the installation in motor homes. Please contact Thetford if you wish to
install in any other vehicle.
The refrigerator is provided with a 3 wire 12v input cable:
-
red: +
- white: -
- black: E+ (powerless signal, to prevent 12v power supply from entering the heating
device of the refrigerator whenever the engine of the vehicle is not running)
To connect the + and - pole
Connect the red and white wire directly without any breakers (e.g. contact) to one of the vehicle’s 12v power
sources.
The 12v connection is protected on the PCB by a 30 A fuse. The control current part of the PCB is protected
by a 5 A fuse.
To connect the E+ pole
Conect the E+ pole to a 12v connecting point that shows that the vehicle’s engine is running (engine running:
12v, engine not running: no voltage= 0v)
- 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 (with a minimum of 6 mm²) to ensure optimum
performance of the refrigerator.
- Position the 12 V power lead in such a way that it cannot come into contact with hot or
sharp parts.
