Tribute IMALA, Owner'S Handbook Manual

Page: 21 / 62

Overview
The EC155 Power Supply Unit incorporates a
12 amp battery charger that supplies 12V DC
power to run the leisure equipment and supply
the leisure battery. It also houses the 12V DC
fuses that protect the various 12V circuits, and
the 230V RCD and MCB’s that protect the
various mains circuits.
Features of the PSU
RESIDUAL CURRENT DEVICE (R.C.D.) &
MINIATURE CIRCUIT BREAKERS
(M.C.B.)
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 your Tribute handbook and
information wallet supplied with your vehicle.
12v DC Fuses
These fuses are provided to protect the
various 12V circuits from an overload or short
circuit. If a fuse does blow, the cause of the
fault should be investigated before a
replacement. When replacing a fuse, always
replace with a fuse of the correct value, never
replace with a higher value as this could
damage the wiring harness. Details of fuse
ratings are given in your Tribute handbook and
information wallet supplied with your vehicle.
Power Switch
The power switch turns on the internal battery
charger that will charge the batteries and
provide 12V power to the interior of the
vehicle. The switch will illuminate when the
unit is plugged into the mains supply and the
charger is turned to the ‘ON’ position.
Cautionary Note
Apart from the changing of fuses and
the testing and resetting of the RCD and
MCB’s no maintenance is required on
the PSU unit. If a problem develops
with your unit please contact your
supplying dealer or a qualified
electrician.
