ELECTRICAL SYSTEM
MAIN SWITCHBOARD 12V
On the main switchboard there is a main rotary switch labelled "ON" and "OFF".
This switch controls the 6 (XT12) or 8 (XT17) individually switched and fused 12-volt DC circuit
breakers for the caravan’s accessories. The function of each circuit is clearly labelled on the
switch panel.
Flip the required switch to "ON" and that circuit is now working. There is an LED in each switch
so you can easily see what circuits you have switched on.
Only switch on what circuits you need as switching on all circuits and not using them is
consuming precious power supply.
If you are travelling with a portable fridge in the front compartment of XT12 model make sure
you have the "DC OUTLET" switch "ON" make sure you turn the main switch "ON”.
If you are travelling with the installed Ventrifigo fridge AND a portable fridge in the front
compartment. Make sure you turn on both "REFRIGERATOR" and "DC OUTLET" and make
sure you turn the main switch "ON".
NOTE: The LPG gas detector is wired directly to the rotary switch in the "ON" position
and is protected by a 3 Amp fuse located near the Gas detector. As soon as you turn on
the rotary switch the gas detector will sound an audible self-test for approximately 5
seconds and will then stop and the green LED will be on and the detector operational.
The LPG gas detector will come in caravans after November 2015.
240V INVERTER
The Powertech 1000W inverter takes 12-volt power from the battery pack and convert it to 240V
AC power with a capacity of 1000 watts. It is protected internally as well as by a resettable
circuit breaker on the main control box and is marked "Inverter" You can use it to power 240volt
appliances that have a total power draw of 1000 watts. As there are two outlets and the total
draw on BOTH outlets should not exceed 1000watts continuously. The inverter is a modified
Sine wave device and as such you should check the suitability of your appliances.
Refer to the inverter owner’s manual for a more comprehensive understanding of the unit and
its options.
This unit comes with two additional RCD's that plug into the 3 pin plugs on the inverter.
RCDs (residual current devices), also commonly called safety switches, are designed to cut the
power in a fraction of a second in the event of a fault condition, thereby preventing
electrocution.
The unit has a test and reset function and is rated to 10A

240V
Another option when charging your battery system is to utilize 240V power. Ideal for when your
caravan is at home or on a powered camp site. To get the 240V charging process started you will
need to connect a 240V 15Amp power lead to your 240V inlet –
the inlet can be located at the front of
the caravan on the drivers’ side panel.
This will provide the power to your Powertech Battery Charger.
To ensure you are transferring this power through to your batteries check that the main switch on the
battery charger is turned "ON"
– switch can be located at the bottom of the charger
. If it is turned
"OFF" then no power will flow to the battery set.
There are 5 "dip" switches located on the charger, the dip switches have different combinations to
suit different battery types. From the factory your caravan will have ‘AGM’ batteries installed,
therefore you will need to make sure the dip switches are set to ‘2’ and ‘5’.
In the Powertech battery
charger manual there are range of dip switch settings for different battery types.
Turn on the power switch, the "POWER ON" LED lights up. This indicates the device is ready for
charging. The "BULK" LED will then light up, meaning the battery charger is beginning at the first
stage of charging.
The first stage is to ensure battery is always charged at the maximum charging condition. This is to
boost up the charging cycle and particularly to wake up a weak battery to absorb energy.
After 10-20 mins the charger will switch to the second stage, the "BULK" LED remains ON, the
battery is charged at the maximum current to the battery.
At the third stage the charger will switch to "ABSORBTION" mode and the red LED goes out and the
yellow LED lights up. The charger is delivering constant voltage to the battery at reduced current.
At the fourth stage, the battery has been charged to about 90% of its rated capacity. The "ABSORBTION" LED
goes out and the "FLOAT" LED lights up. The charging current is decreased and the charging voltage is held at a
constant level. Battery is now under "FLOAT" constant charging.
The system is protected by an external 60amp fuse marked "Battery Charger".
SOLAR
When you are in a remote area with no 240volt supply available the solar panels will provide power to
the battery pack (and the breakaway battery). The rate of charge is dependent upon the available
sunlight and your use of appliances.
The solar controller is there to regulate the charge coming from the solar panels to ensure there is no
damage done to the batteries.
