There are available several proprietary makes
of equipment for the purpose (e.g. Martindale
tester unit).
Check all motorhome equipment is set up
to accept the site supply before actually
switching on.

Mains unit

The mains unit replaces the conventional fuse
box. Similar, but larger units are often fitted
in modern houses. The unit gives overload
and earth leakage protection for the 230V
electrical supply in your motorhome.
For normal operation all switches on the unit
need to be in the ON position. The switches
on the left of the unit are known as MCB's
(miniature circuit breakers).
In the event of a fault the MCB "trips", i.e.
automatically moves to the OFF position.
After elimination of the fault the MCB. can be
reset by switching to the ON position (against
the spring pressure in an upwards direction).
If an earth fault develops or a person were to
touch a live piece of equipment, the leakage of
current to earth should immediately operate
the RCD (residual current device) and "trip"
the main switch, to its OFF position.
This switch is only resettable after elimination
of the fault.
To reset, operate the switch as for MCBs.
Every time you connect to a site supply the
RCD should be checked by operating the
test button marked "T". The unit should
immediately switch to the OFF position. If the
unit does not switch off, do NOT use the mains
supply system and a qualified electrician
should be called.
If the unit does switch off, the test is complete
and the switch can be reset restoring the
supply back to normal.
Having too many appliances switched on at the
same time will trip the MCB. This is a safety
measure.
It is essential that connections are made
exactly as shown. If terminal markings are
not in accordance with the diagram they must
be ignored. If in doubt consult a qualified
electrician.
It is possible that all of the 230V mains
electrical equipment may not be able to be
operated simultaneously.
Many motorhome park mains hook-up points
provide a maximum output of 16 amps and on
some continental sites the available output
may be as low as 5 amps.
exceeds the site supply it may trip the park's
circuit breaker. Please check the available
mains output in amps with your site operator.
No appliance shall be used outside

when being connected to the internal
socket.
THE ELECTRICAL SYSTEM – 12 VOLT
Your motorhome is fitted with a dual stage
power supply/charger supplying 14.2V to your
leisure battery and between 13.6/13.8V to
the habitation unit. This converts the 230V
AC supply to 12V DC. This enables the 12V
equipment in the motorhome to function and
charges the motorhome leisure battery.
fully charged leisure battery should read
12.7V on the voltmeter mounted in the control
panel. During charging the control panel will
temporarily read between 14.2/13.8V.
The charger is capable of charging leisure
batteries and will not overcharge. The 12V
system is designed to operate with a leisure
battery in circuit and should not be turned on
without one connected. The 12V supply to the
If your loading Motorhome services can be isolated via the
12V on/off switch on the control panel.
The 12V electrical systems fuses are located
either in a bed box or under the fixed bed. It
has 14 fuses, each having identification to their
particular use. If a fuse is to be replaced it
must be with one of the same rating as the one
that is removed.
For more information on the power supply
please refer to the specification page in your
service manual.

Auxiliary battery storage/mains inlet

The battery is located under the floor in the
motorhome in a sealed compartment.
Autograph compartment will accommodate
two batteries up to 110 amperes/hours capacity.
The Advance compartment accomodates one
battery of up to 110 amperes/ hours capacity.
The battery must be placed in the tray provided
in the battery storage compartment, and this
