8.5 Using the System
Power Supply Unit - Component Layout (see
image on previous page)
The PSU is located in the front offside bed box
area.
Activating the System
The system has a shutdown feature that can be
used when the vehicle is in storage. This allows
the leisure electronics to be turned off when not
required to save battery power. When in the off
state the alarm and tracking system supplies are
still active, all other supplies are turned off.
Before using the system, please ensure the
system shutdown switch is in the on position
(button in) the system is now active.
Connecting to the Mains 230V supply and
Safety checks
For your safety it is IMPORTANT that you follow
these connections instructions each time
your Leisure Vehicle is connected to a mains
supply. This section assumes that the system
is complete and that a Leisure battery has been
installed (see 8.17).
A) Ensure suitability of the Mains Supply.
Your Leisure Vehicle should only be connected
to an approved supply that meets the
requirements of BS7671 or relevant harmonised
standards. In most cases the site warden will
hold information regarding suitability of supply.
If using a generator, you also need to comply
with the requirements / instructions supplied
with the generator. Please note that some
electronic generators may not be compatible
with your leisure system. Further generator
operational information is contained in section
8.15.
B) Switch the PSU Battery Charger / Power
Converter OFF.
Locate the green ‘Charger’ power switch on the
PSU and ensure the switch is in the off position
(button out) before connection to the mains
supply.
C) Connect the Hook-up Lead.
Firstly, connect the supplied hook-up lead
(orange cable with blue connectors) to the
Leisure Vehicle and then connect to the mains
supply.
D) Check Residual Current Device operation.
Locate the RCD within the PSU and ensure the
RCD is switched on (lever in up position). Press
the ‘Test’ button and confirm that the RCD turns
off (lever in down position). Switch the RCD
back to the on position (lever in up position). If
the test button failed to operate the RCD see
section 8.14.
E) Check Miniature Circuit Breakers
Locate the MCB’s within the PSU (adjacent to
the RCD) and ensure they are all in the on (up)
position. If any MCB’s fail to ‘latch’ in the on
position see section 8.14.
F) Turn the PSU ON.
Locate the black ‘Shutdown’ button and ensure
it is in the on position (press button in). Locate
the green ‘Charger’ switch on the PSU and turn
to the on position (press button in). The charger
switch will illuminate when turned on.
G) Check correct Polarity.
Locate the ‘Reverse polarity’ indicator on
the PSU and ensure that the indicator is NOT
illuminated. If the indicator is illuminated see
section 8.15.
H) Check operation of equipment.
It is now safe to operate the 12V and 230V
equipment.
Operation while driving
The power control system is designed to
shutdown parts of the system while the engine
is running. This is to meet Electro Magnetic
Compatibility (EMC) regulations and to ensure
the safe operation of the motorhome. With
the engine running the control panel will flash
the leisure battery and vehicle battery LEDs to
indicate that the batteries are being charged.
Please ensure the system shutdown switch
on the PSU is in the on (button in) position
before driving (see 8.5). This will ensure the
electronic system is active and will therefore be
able to control the charging process, supply the
refrigerator and monitor other system circuits.
If / when fitted, designated 12V sockets, en-
route reading lights and en-route heating will
remain operational while the engine is running.
