PLEASE READ ALL

THE INSTRUCTIONS BEFORE USING

THIS POWER INVERTER.

WARNING:

o reduce the risk of fire, electric shock, explosion or

injury:

• Do not connect to AC distribution wiring.

• Always disconnect appliances from the inverter and turn the

inverter off before working the appliance. Multiple outlet

power strips with switches and power switches and circuit

breakers only interupt power to the "live" socket terminals.

The neutral terminals remain powered with respect to the

earth terminals.

• Do not make any electrical connections or disconnections in

areas designated as IGNITION PROTECTED including DC

cigarette lighter type plug connections and ring terminal

connections. Always disconnect appliances from the inverter

before removing the inverters power source.

• Do not obstruct or block the air vents on the inverter.

• The inverter is not a toy, keep away from children.

CAUTION:

• Do not use with positive earth electrical systems (the

majority of modern vehicles are negative earth). A reverse

polarity connection will result in a blown fuse and may cause

permanent damage to the inverter.

• The inverter will not operate high wattage appliances or

equipment that produces heat, such as dryers, microwave

ovens and toasters.

• Earthing the neutral will cause the inverter to shut down.

• Do not operate the inverter if it is wet. Water and electric do

not mix.

• Do not install the inverter in the engine compartment, the

inverter must be used in a well ventilated postion.

• This inverter is not tested for use with medical equipment.

IMPORTANT CABLE INFORMATION

Substantial power loss and reduced battery operating time

result form inverters installed with cables that are not able to

supply full power. Symptoms of low battery power can result

from cables that are either excessively long or of an

insufficient gauge. Marine installations are subjected to

vibrations and stresses that exceed those of other mobile

installations, therefore the installer/operator should be

especially aware or the requirements to maintain secure,

tight water resistant electrical connections and provide for

strain relief for DC cables and appliance wiring. Cable

insulation must be the appropriate type for the environment.

Introduction

The inverter supplies continuous power in the form of one

household type socket. The inverter has enough power to

run almost any household or electronic appliance. Safety

features include automatic shut down and a low battery

alarm to prevent damage to your battery.

CONTROLS, INDICA

TORS AND CONNECTORS

The front panel of the inverter provides two LED indicators.

The green LED indicator shows the unit is working correctly

when lit.

The red LED indicator shows inverter shut down

from overload, over voltage or over temparature. The

inverter is fitted with an on/off switch, the on/off switch is

also used to force reset the inverter circuits in case of

overload, over voltage or over temparature. Power is

supplied through the three pin

AC plug and DC input power

is suppiled via the rear panel.

HOW INVERTERS

WORK

Principle of operation.

The inverter converts low voltage DC (direct current) from a

battery or other power source to standard

AC (alternating

current) household power. The inverter converts power in

two stages. The first stage is a DC to DC conversion

process that raises low voltage DC from the inverter input

to high volts DC. The second stage is the actual inverter

stage that converts the high DC into AC power.

The DC to DC converter stage uses modern high frequency

power conversion techniques that have replaced bulky

transformers found in less technologically advanced models.

The inverter uses advanced MOSFET transistors in a full

bridge configuration, which ensures excellent overload

capabilities and allows the inverter to operate reactive loads

such as small induction motors.

The output waveform.

The AC output waveform is known as a “modified sine

wave”. It is a waveform that has characteristics similar to the

sine wave shape of standard household power. This type of

waveform is suitable for most AC loads, including linear and

switching power supplies used in electronic equipment,

transformers and motors.

The modified sine wave produced by the inverter has an

RMS (root mean square) voltage, which is the same as

standard household power. Most AC voltmeters (analog and

digital) are sensitive to the average value of the waveform

rather than the RMS value. They are calibrated for RMS

voltage under the assumption that waveform measured will

be a pure sine wave. Voltmeters will not read the RMS

voltage of a modified sine wave correctly. The reading will

be around 20-30 volts too low when measuring the inverters

output.

INSTALLING THE INVERTER

Power source requirements

The power source for the inverter must provide between 1

and 15 volts dc and must be able to supply the necessary

current to operate the load.

The power source may be a

battery or a well regulated DC power supply

. To obtain a

rough estimate of the current in

Amps the power source

must deliver simply divide the power consumption of the

load by 10.

EXAMPLE: If a load is rated at 300 watts AC, the power

source must be able to deliver 300 divided by 10 = 30

Amps.

CAUTION:

The inverter must be connected only to batteries with a

nominal output voltage of 12 volts.

The inverter will not work

if connected to a 6 volt battery and will sustain permanent

damage if connected to a 24 volt battery.

Connecting to a power source using provided cables

If the inverter is to be used for extended periods at power

levels above 150 watts, direct connection to the power

source is required. Use the leads provided to connect

directly to the 12-volt power source using the following

guidelines

• Check that the inverter is switched off and no flammable

fumes are present

• Connect the black cable to the post marked negative (-) on

the back panel of the inverter. Connect the black battery clip

to the negative (-) terminal of the battery.

• Connect the red cable to the post marked positive (+) on the

back panel of the inverter. Connect the red battery clip to

the positive (+) terminal of the battery.

• Check that all the connections between battery clips and

terminals are secure

CAUTION:

Loose connections may cause overheated wires and melted

insulation. Check to make sure you have not reversed the

polarity.

Connection to load

The inverter is equipped with a standard AC household type

socket. Plug the cord from the appliance you wish to use

into the socket. The green LED indicator light shows the

inverter is functioning normally. Make sure that the combined

load requirement of your equipment does not exceed the

rated watts.

The inverter is engineered to be connected directly to

standard electrical and electronic equipment in the manner

described above. Do not connect the power inverter to

household or recreational vehicle AC distribution wiring. Do

not connect the inverter to any AC load circuit in which the

neutral conductor is connected to earth or to the negative of

the DC (battery) source.

WARNING:

Never connect to AC distribution wiring.

CAUTION: RECHARGEABLE

APPLIANCES

Certain rechargeable devices are designed to be recharged

by plugging them directly in to a household socket. This type

of device must never be used in the inverter. The device will

damage the inverter. Do not use the inverter to recharge

items that can be plugged directly into a household socket.

This problem does not occur with the vast majority of

battery-operated equipment. Most of these devices use a

separate charger or transformer that is plugged into an AC

household socket.

The inverter is easily capable of running

most chargers and transformers.

POSITIONING THE INVERTER

For best operating results, the inverter should be placed on

a flat surface such as the ground, car floor or seat, or

another solid surface.

The unit is equipped with a 1m-power

cord for easy positioning. The inverter should only be used

in locations that meet the following criteria.

• Dry: do not allow water or liquids to come into contact with

the inverter

•

Cool: ambient air temperature should be between 30°F (-1

°C) non-condensing, and 105°F (40°C). Do not place the

inverter on or near a heating vent or any equipment, which

is generating heat above room temperature. Keep the

inverter out of direct sunlight.

• Ventilated: keep the area surrounding the inverter clear to

ensure free air circulation around the unit. Do not place

items on or near the unit whilst it is operating. A fan is

helpful if the unit is operating at maximum power outputs for

extended periods of time. If the internal temperature of the

inverter exceeds 90°C the inverter will shut down

and restart when it has cooled.

• Safe: do not position the inverter near any flammable

material or in a position that may accumulate flammable

fumes or gases.

OPERATING TIPS

Rated versus actual current draw.

Most electrical equipment has labels that indicate the power

consumption in amps or watts. Ensure the power

consumption of the item you wish to operate is specified at

the rated watts or less. The inverter has overload protection

so it is safe to try and operate equipment rated at the

specified watts or less. The inverter will shut down if it is

overloaded. The overload must be removed before the

inverter will restart; resistive loads are the easiest for the

inverter to run. However larger resistive loads, such as,

stoves and heaters usually require more wattage than the

inverter can deliver on a continuous basis. Inductive loads

such as, TV’s and stereos require more current to operate

than resistive loads of the same wattage rating. Induction

motors as well as some televisions may require 2-6 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 of

determining if a specific load can be started and how long it

will run. The inverter is fitted with overload protection so will

simply shut down if overloaded. To restart the unit after

overloading remove the overload and if necessary turn the

power switch off and then on.

Battery operating time.

With a typical vehicle battery, a minimum operating time of 2

to 3 hours can be expected. In most instances, 5 to 10 hours

of operating time is achievable however it is recommended

that the operator starts the vehicle every 2 to 3 hours to

recharge the battery system thus guarding against

unexpected equipment shut down and ensuring that there is

still sufficient power to start the engine. The inverter’s built in

alarm will sound if the DC voltage drops below 10.5V.

The inverter can be used whether or not the vehicles engine

is running however the inverter will not operate whilst the
