EQUIPMENT COMPONENTS
INTRODUCTION
The inverter gives a continuous 230V, 50Hz power supply via a standard 3-pin
socket and is capable of running a range of household appliances, including
TVs, camcorders, laptops, lamps and power tool chargers etc., depending
upon the rating of the inverter.
Safety features include automatic shutdown and a low battery alarm - to
avoid the possibility of damaging your battery.
CONTROLS INDICATORS AND CONNECTORS
An ON/OFF rocker switch turns the inverter On and Off and will reset the
inverter circuits.
The back panel provides DC connections for battery clamps (or cigar lighter
connector on the CI400B model).
Two LEDs are provided on the front panel.
• The GREEN LED illuminates when the inverter is connected, switched
ON, and working correctly.
• The RED LED, when illuminated, indicates that the inverter is in a
fault condition and has shutdown from overload, excess voltage or
overheating.

SUITABLE POWER SOURCES
In order to operate the inverter and supply power to an appliance, a suitable
DC power supply is required. This can be a vehicle or caravan battery,
portable power pack, or an independent 12 Volt battery. For most
applications, a ‘deep cycle’ battery is recommended for best performance.
The size of the battery used will determine how long the inverter will supply
power to an appliance and how well the inverter will perform. Most batteries
are marked with their size in Amp Hours (AH).
Because 12 Volt inverters are capable of drawing high currents, the inverter
should only be connected to a suitable size battery. Connection to an
undersized battery could damage the battery and will result in the inverter
shutting down within a short period due to low battery voltage. The amount
of power drawn from the battery is proportional to the inverter load.
DETERMINING SUITABLE LOADS
All appliances have a rating plate that shows the amount of power (Watts)
used, or the current (Amps) drawn during normal use. The following table
shows the load that can be run by the inverter.
Some appliances that use an electric motor or transformer may draw
considerably more than their rating when first turned on. These are known as
inductive loads and are the most difficult for the inverter to run.

Resistive loads are the easiest for the inverter to run. However, larger resistive
loads, such as heaters, usually require more power than the inverter can
deliver on a continuous basis. Inductive loads, such as TVs and stereos,
require more current to operate than do resistive loads of the same wattage
rating. Induction motors, as well as some televisions, may require 2 to 6 times
their wattage rating to start up. The most demanding in this category are
those that start under load, such as compressors and pumps.
Testing is the only definitive way to determine whether a specific load can be
started and how long it can run. The unit will simply shut down if it is
overloaded. To restart the unit after a shutdown due to overloading,
disconnect the load and if necessary turn the power switch OFF then ON.
The following table is a guide to the approximate AC power drawn by various
appliances. The DC Amps column shows the approximate power drawn from
the 12 Volt supply.

CONNECTION AND POSITIONING
POSITIONING OF THE INVERTER
The inverter should always be placed on a flat, level surface and should only
be used in locations that meet the following criteria:
DRY - Do not allow water/other liquids to come into contact with the inverter.
COOL - Do not place the inverter on or near a heating vent or any piece of
equipment which is generating heat. Keep the inverter away from direct
sunlight.
VENTILATED - Keep the area surrounding the inverter clear to ensure free air
circulation around the unit. Do not place items on or over the inverter during
operation. A fan is helpful if the inverter is operating at maximum power for
extended periods. The unit will shut down if the internal temperature exceeds
65OC. The unit will restart after it cools.
SAFE - Do not use the inverter near flammable materials or in locations that
may accumulate flammable vapours.
CAUTION: THE INVERTER MUST BE CONNECTED ONLY TO BATTERIES WITH
A NOMINAL OUTPUT VOLTAGE OF 12 VOLTS. THE UNIT WILL NOT
OPERATE FROM A 6-VOLT BATTERY AND WILL SUSTAIN PERMANENT
DAMAGE IF CONNECTED TO A 24-VOLT BATTERY.
CAUTION: DO NOT USE WITH POSITIVE EARTH ELECTRICAL SYSTEMS (THE
MAJORITY OF MODERN VEHICLES AND LORRIES ARE NEGATIVE EARTH).
The inverter is provided with battery cables with clamps for connection to a
suitable battery (or a fused cigarette lighter plug - CI400B model only).
EXTENSION CABLES
Avoid using an extension cable between the DC power source and the
inverter DC input. Using an extension this way will create a voltage drop
causing reduced efficiency and output. Any extension cable should be used
between the inverter AC output and the AC appliance. An extension cable
up to 30m may be used but greater lengths will result in a noticeable drop in
power.
Any cable used between the appliance and the inverter must be of the
correct diameter and length, otherwise power loss or reduced operating time
may occur.
Marine installations are also subjected to vibration and stresses that exceed
those of other mobile installations. Therefore ensure all connections are tight,
water resistant and have suitable strain relief for DC cables etc.

8
In a stationary, land based installation, the earth terminal should be
connected to a metal earthing stake driven into the ground. If the battery
system powering the inverter does not have a connection to ground, one of
the battery terminals (commonly the negative terminal), should also be
connected to the earthing stake.
In a vehicle where the inverter is wired directly to the battery, the earth
terminal is simply connected to the vehicle chassis. If the inverter is to be used
in a vehicle on a temporary basis, and will be powered via the cigarette
lighter socket in the vehicle, the earth terminal should be connected via a
short link to either the negative or positive DC input terminal of the inverter,
depending on whether the vehicle has a negative or positive chassis
connection. Most modern vehicles have a negative chassis connection.
However when using the inverter to power equipment used outside the
vehicle, an earthing stake should be used, as described above.
In a boat, the grounding terminal should be connected to the existing
grounding system, which may be the hull of the craft, or a network of ground
wires.
Cable installation must be the correct type for the environment.
• Position the inverter as far away as possible from the television, the
antenna, and the antenna cable. Use an extension cable if
necessary.
GROUNDING CONNECTION
WARNING: Before using this inverter you must provide a ground
connection.
On the rear panel of the inverter is a terminal fitted with a screw. This terminal
is connected to the case of the inverter and also to the earth terminal of the
AC output socket. The use of this terminal will depend on your particular
installation. In any installation, heavy duty insulated wire should be used for
this connection.

9
NOTE: The grounding terminal of the AC outlet is connected to the
neutral terminal. This is the same as a standard household power
point where the neutral line is bonded to grounding and there is
normally no voltage between them.
CONNECTING TO POWER SOURCE VIA CIGARETTE LIGHTER PLUG
(CI400B ONLY)
The cigarette lighter plug is suitable for operating the inverter at power
outputs up to 200 Watts. The tip of the plug is positive and the side contact is
negative. Connect the inverter to the power source by inserting the cigarette
lighter plug firmly into the cigarette lighter socket of a vehicle or other DC
power source.
Connect directly to the car battery when operating appliances above 200
Watts.
NOTE: Most vehicle cigarette lighter circuits use fuses rated at 15 to 20
Amps or greater. To operate at full power, either use the battery
clamp cable (supplied) or directly wire to the power source with
suitable wire and fuse (not supplied).
CAUTION: REVERSE POLARITY CONNECTION WILL RESULT IN A BLOWN
FUSE AND MAY CAUSE PERMANENT DAMAGE TO THE INVERTER.
(ALWAYS ENSURE THE LEADS ARE CONNECTED AS BELOW).
CONNECTING TO A POWER SOURCE VIA CABLES
Use the cables provided to connect the inverter directly to the 12 volt power
source using the following guidelines:
1. Check that the inverter power switch is turned OFF and that no flammable
fumes are present.
2. Connect the black cable to the black terminal marked “(-)” on the back
of the inverter. Connect the black battery clip to the negative terminal of
the battery.
3. Connect the red cable to the red terminal marked “(+)”on the back of
the inverter. Connect the red battery clip to the positive terminal of the
battery.
4. Check to ensure that all connections between battery clips and terminals
are clean and secure.
CONNECTING THE LOAD
With the inverter connected to the power source, but switched OFF, ensure
the appliance is also switched off before plugging the cable from the
appliance, into the AC socket on the inverter.
Switch ON the inverter and the green LED will illuminate to indicate that the

10
inverter is functioning. Make sure the load of your appliance does not exceed
the rated output of the inverter (in Watts) before switching on the appliance.
Always unplug the inverter when not in use.
Always unplug the inverter when starting the engine of the vehicle.
WARNING: Do not UNDER ANY CIRCUMSTANCES connect the inverter
to household AC circuits.
RECHARGABLE DEVICES
CAUTION: SHOULD YOU ENCOUNTER ANY RECHARGEABLE DEVICE
DESIGNED TO BE RECHARGED BY PLUGGING DIRECTLY INTO AN AC
SOCKET, DO NOT USE THE INVERTER TO RECHARGE SUCH DEVICES AS
THEY COULD DAMAGE THE INVERTER.
This problem does not occur with the majority of battery operated equipment.
Most of these devices use a separate charger or transformer that is plugged
into an AC socket. The inverter is capable of running most chargers and
transformers.
CAUTION: MAKE SURE THAT THE BATTERY'S VOLTAGE NEVER EXCEEDS
15VDC. CONNECTING THE INVERTER TO A DC POWER SOURCE
GREATER THAN 15VDC WILL INVALIDATE THE WARRANTY AND MAY
DAMAGE THE INVERTER.

11
OPERATION
WARNING: If you connect the wires to the incorrect terminals, the
polarity will be reversed and the inverter will be damaged. Reversing
the polarity will invalidate your manufacturer’s warranty.
When connecting to an appliance incorporating an electric motor such as a
compressor, drill or fan, always ensure that the power rating of the inverter is
adequate for the power rating of the appliance.
If the inverter makes a beeping sound, switch off the appliance, unplug the
inverter and restart the vehicle engine. The beeping sound is simply the low-
battery warning which indicates that the voltage of your battery is getting
low. The inverter will shut down automatically if you do not restart the engine
and continue the use of the inverter. This will leave the vehicle battery at
about 10.5 VDC, enabling you to start your engine and resume operation of
the inverter.
To avoid excessively discharging the vehicle battery, it is advisable to let your
engine run for a while after a period of using the inverter. This allows the
vehicle battery to recharge. Refer to the chart on page 5 (Suitable Power
Sources), as an indication of run-times based on the worst case situation.
Always remember to disconnect the AC inverter before using a battery
charger to recharge your battery. Failure to disconnect the inverter prior to
connecting a charger may result in an input spike which will damage the
inverter. CONNECTING THE INVERTERS INPUT TO A BATTERY CHARGER WILL
VOID THE WARRANTY.

12
SYSTEM PROTECTION
The inverter will switch off automatically if the total wattage of the
appliance(s) exceeds the inverter output capacity. This will also happen if the
temperature of the inverter exceeds 65OC due to prolonged use.
The protection circuit will also switch off the output in the case of short-circuit
or overload. If this should happen:
1. Switch off the inverter.
2. Disconnect any appliances.
3. Check all connections.
The inverter can be used again when any faults have been rectified.
When the unit is in continuous operation, the AC output may suddenly stop
although there remains a good supply from the battery. This may be caused
by overheating and the inverter should be switched off until it cools down.
WARNING; Never connect the inverter to the battery with the wrong
polarity. This will damage the unit and invalidate the warranty.
MEASURING AC VOLTAGE
The output wave of the AC inverter is a modified sine-wave. If you choose to
measure the AC output voltage, you must use an authentic RMS volt meter.
Using any other type of voltage measuring device will result in an AC voltage
reading that is up to 20 to 30 volts lower than the rated value. The reading will
only be accurate when using an authentic RMS voltmeter.

FUSE REPLACEMENT
If an external fuse on the rear of the unit blows, there is most likely a short
circuit or overload in the DC wiring, or the polarity has been reversed. Find
and correct the problem before replacing the fuses. The quantity and rating
