Leisure Battery / EC325 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.
EC325 PSU (Power Supply Unit)
Overview
The EC325 Power Supply Unit incorporates a
25 amp battery charger that supplies 12V DC
power to run the leisure equipment and supply
the leisure battery.
It also houses the 12VDC fuses that protect
the various 12V circuits, and the 230V RCD
and MCB’s that protect the various
mains circuits.
Features on the PSU
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.
