The 12 Volt Electrical System
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 area. This converts the 230V AC
supply to 12V DC. It enables the 12V equipment
in the motorhome to function and also charges
the motorhome leisure battery. A fully charged
leisure battery should read 12.7V on the
voltmeter 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
Motorhome services can be isolated via the 12V
on/off switch on the control panel.
The 12V electrical system’s 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.
Upon Arrival At A Motorhome Site
1. Ensure the mains supply is suitable for
your electrical installation and appliances.
Check the current, voltage, frequency and
polarity are correct.
2. Ensure the electrical installation will be
properly earthed when connected. Never
accept a supply from a socket outlet or
plug thats lacks a proper earth.
3. Check that any Residual Current Device
(RCD) within the Power Distrubution Unit
(PDU) has been tested within the last
month. (To test, follow steps 4 to step 9).
4. Make sure the switch at the site supply
point is off.
5. Make sure the RCD is switched off.
6. Lift lid of the electricity inlet on the
motorhome and insert the mains site lead.
(The 230V mains inlet is located on the
side of the motorhome and is identified by
a lightning bolt).
7. Remove the cover from the socket outlet
provided at the site and insert the mains
site lead plug.
8. Turn on the site supply point. (If there is no
switch the power will already be live.)
9. Coil excess cable in loose coils on the floor,
not on a drum or in a container.
10. Switch on the motorhome RCD. Press the
test button - the RCD should switch off
breaking the circuit - this indicates RCD is
functioning correctly.
11. Move the RCD switch to the on position.
12. In any case of doubt, consult the site owner
or their agent.
13. Interior outlet sockets must only be used
with approved appliances.
14. Only use suitable appliances externally.
Leaving The Motorhome Site
1. Switch off the site supply.
2. Switch off the motorhome RCD, then
disconnect the supplied flexible cable.
3. Switch off and disconnect all portable
appliances.
4. Stow mains site lead in a tidy state.
5. In any case of difficulty consult an
approved electrical installation contractor.
It is dangerous to attempt modifications
yourself and may invalidate your warranty.
6. Lamp-holder plugs (bayonet-cap adapters)
should not in any circumstances be used as
a source of power.
7. Replace the cover of the socket outlet at
the site supply point. It is dangerous to
leave the supply socket or supply flexible
cable live.
8. Every 12 months, the motorhome electrical
installation should be inspected and
tested. A report on its condition should be
obtained as prescribed in the Regulations
for Electrical Installations, published by the
Institute of Electrical Engineers.
Generators
1. Switch off all appliances, all circuit breakers
and RCD.
2. Start the generator and allow to run for a
few minutes to stabilise.
3. Connect the motorhome to the generator
using an approved mains site lead.
4. Switch on 16amp circuit breaker.
