• Locate the power switch on the PSU and turn
to the ‘ON’ position. The switch will illuminate
when turned on.
It is now safe to check the operation of the 12V
and 230V equipment.
Overseas Connections
Connection to mains voltage overseas requires
particular attention. Electricity supplies abroad may
be of reverse polarity. The significance of this is that
when an appliance is switched off, it may not be
electrically isolated.
It is useful to check the polarity of the supply so
that the connection can be made neutral to neutral
and live to live as recommended. Your Auto-Trail,
however, is fitted with a double pole circuit breaker.
Check that all Motorhome equipment is set to accept
the site supply prior to switching it on.
Please note that if too many appliances are in
operation at one time, the MCB may trip. This
is a safety measure. On some sites, the power
is not sufficient to power all appliances. If in
doubt, consult the site manager or warden.
When replacing 12V fuses always with a fuse
of the correct value. NEVER replace with a
higher value / rating as this could damage
the wiring harness.
PSU Courtesy Light
The cupboard in which the PSU is situated is
equipped with a courtesy light that is activated when
the cupboard door is opened. This light is supplied
by the on board leisure battery of the vehicle when
stationary. Should a fault occur on this circuit and
the light fail, starting the engine will reconnect the
light to the vehicle battery circuit to allow fuses and
circuit breakers to be checked etc.
Wiring of connecting cable and Motorhome
mains inlet:
Pitch outlet supply
Cable plug
Cable coupler
Motorhome mains inlet
The cable plug is connected to the cable coupler by
a 2.5mm flexible 3-core cable.
Warning:
It is essential that connections are made exactly
as shown. If the terminal markings are not in
accordance with the diagram, they must be
ignored. If in doubt, consult a qualified electrician.
Generators
If a generator is fitted, the vehicle must be regularly
serviced to achieve the optimum performance. Engine
speed is used to govern the output and frequency of
the unit in KW and Hz, and if this is allowed to vary
beyond a safe level, permanent damage could be
caused to certain electronic equipment such as 12V
chargers etc.
IMPORTANT
Periodically, preferably not less than once
a year, the Motorhome electrical installation
should be inspected and tested. A report on the
condition should be obtained as described in the
Regulations for Electrical Installations,
published by the Institute of Electrical Engineers.
It is important that the main switch at the site
point should be switched off, the supply flexible
cable disconnected and any cover replaced on
the socket outlet at the site supply point. It is
dangerous to leave the supply flexible
cable connected.
If a fault should develop with your electrical
system that is not described in the ‘fault table’
and your supplying dealer cannot resolve the
problem, Sargent Electrical Systems operate a
telephone help line that is available during
normal office hours.
