CONTROLS
The mains protection devices are located to
the right hand side of the unit, and consists of
a 25 amp RCD (Residual Current Device)
which will rapidly break the mains circuit
should a fault occur.
At the left hand side of the RCD are two MCBs
(Miniature Circuit Breakers) which protect the
individual mains circuits within the motorhome
against overloading. Situated above the RCD
is an illuminated ON/OFF switch which turns
the Battery Charger/Power Supply ON or OFF.
The remaining item is the 12 volt fuse
assembly, the six blade type fuses protect
individual 12 volt circuits within the
motorhome, and are marked with their function
to the left hand side. To remove the fuses
simply pull forward away from the P.C.II and
push in to replace. The fuses fitted in the P.C.II
are a similar type to fuses fitted to modern cars
and can be ‘borrowed’ from the car in an
emergency.

BATTERY CHARGER/POWER SUPPLY
The battery charger is an all electronic switch
mode power supply, capable of providing 12
amps continuously at 13.8 volts DC. The unit is
designed to be used as a very efficient battery
charger when a battery is in situ and the
motorhome is connected to mains supply (it
cannot overcharge the battery even when left
connected for long periods of time) or as a
power supply when no battery is connected
providing the power to operate the equipment
within the motorhome.
R.C.D. TEST BUTTON
This should be operated at regular intervals in
order to check and ensure effective operation
of the facility. See label fitted adjacent to the
P.C.11 unit in your motorhome and also the
following RCD/ MCB section.
RCD/MCB PROTECTION
These components are designed to give both
overload and earth leakage protection for the
electrical supply in your motorhome. The
MCBs are better described as mechanical
fuses. In the event of an overload situation, the
circuit they supply is automatically switched to
the OFF position. After elimination of the fault
the MCB should be reset by manually
switching the switch back on again in an
upward direction against the spring pressure.
Normally these MCBs should be left in the ON
position.
The RCD is fitted to provide protection against
earth faults and possible electric shock. In the
event of an earth fault which would cause a
current leaking to earth, either directly or via
the human body, the unit should immediately
trip and switch OFF the supply. After
elimination of the fault it will be possible to
manually reset the RCD to the ON position by
switching the switch in an upward direction
against the spring pressure, and so restore the
supply again.
Periodically it is necessary to test the operation
of the RCD. This is achieved by ensuring that it
is switched in the ON position with an
electricity supply connected and by pressing
the test button marked ‘T’. The unit should
immediately switch to the OFF position.
Provided this happens all is correct and the
switch should be returned to the ON position,
upwards and against the spring pressure, to
restore the supply back to normal. The RCD
also acts as the main switch for the unit and if
it is required to switch off all circuits in the
motorhome this can be achieved by switching
the RCD to OFF.
