EC325 Power Supply Unit
: Owner’s Handbook
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 is fitted.
When replacing fuses, always replace a fuse with
the correct value. Never replace with a higher
value as this could damage the wiring harness.
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.
Reverse Polarity Indicator
This light is designed to illuminate when the live
and neutral mains input supply has been reversed
(crossed over).
If the light illuminates then there is a problem with
either the site supply or the cable connecting the
supply to your vehicle.
The light is designed to work with UK electrical
supplies. If you are using your vehicle outside
the UK this light may illuminate when no fault exists.
In these cases consult the site warden for advice.
System Monitor LED
This LED monitors the circuits within the PSU
to ensure optimum operation.
Please note that 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.
