Leisure Battery / EC500 Power Supply Unit
Leisure Battery
Your vehicle is equipped with a rechargeable
leisure battery that is located in a dedicated
battery compartment within your vehicle.
Locations of leisure batteries vary from model
to model, so please familiarise yourself with your
battery location before using your vehicle for the
first time. The battery is charged via the on board
charging unit when the vehicle is plugged into a
mains supply, or via the vehicle alternator whilst
your Motorhome is being driven.
Connecting and disconnecting the battery
Please ensure that all cigarettes are
extinguished before working in the auxiliary
battery compartment.
Switch off all appliances and lamps before
disconnecting the leisure battery.
• Release the battery securing bolts or securing
straps from the leisure battery.
• Carefully remove the battery from the battery
compartment (please take care – the leisure
battery is extremely heavy).
• Release the battery terminals using a suitably
sized spanner.
To refit the battery, simply reverse the
above procedure.
Please ensure the battery is located safely and
securely before driving your Motorhome.
Any replacement auxiliary battery shall be of the
same type and specification as that originally
fitted by the manufacturer.
EC500 PSU (Power Supply Unit)
Overview
The EC500 Power Supply Unit utilises a battery
charger that supplies 12 volt DC power to run the
leisure equipment and supply the leisure battery.
It also houses the 12 volt DC fuses that protect
the various 12 volt circuits, and the 230 volt RCD
and MCB’s that protect the various mains circuits.
Residual Current Device & Miniature
Circuit Breakers
The Residual Current Device is provided to
protect the user from a potentially lethal electric
shock. The RCD will turn off (trip) if a fault occurs
on the system. To ensure the RCD is working
correctly, the test button should be operated each
time the vehicle is connected to the mains supply.
The Miniature circuit breakers (MCB’s) operate
in a similar way to traditional fuses and are
provided to protect the wiring from an overload or
short circuit. If an overload occurs the MCB will
switch off the supply. If this occurs the cause of
the fault should be investigated before switching
the MCB back on. Details of the MCB ratings and
the circuits they protect are detailed in the back of
this handbook.
12 Volt DC Fuses
These fuses are provided to protect the various
12 volt circuits from an overload or short circuit.
If a fuse does blow, the cause of the fault should
be investigated before a replacement is fitted.
When replacing a fuse, always replace a fuse
