IMPORTANT SAFETY INFORMATION
Please read this manual thoroughly before use and store in a safe place for future reference.
WARNINGS
• For indoor use out of weather only.
• For use with negatively earthed vehicles & systems only.
• Internally bonded for safety, battery DC negative to case & AC socket earth.
• Hazardous voltage inside – do not attempt to open, repair or use if damaged.
• Only connect 230/240V AC appliances that are in safe condition.
• This appliance is not intended for use by young children or infirm persons unless they have been
adequately supervised by a responsible person to ensure that they can use the appliance safely.
• Young children should be supervised to ensure that they do not play with the appliance.
• It is recommended that a type ‘A’ portable residual current device (RCD) be used for added
output protection.
• For independent use, do not connect to buildings.
CAUTIONS
• Batteries should be mounted in a separate well-vented enclosure.
• Even though the inverter is powered from a battery, it still produces dangerously high voltage AC
power and has the potential to fatally injure if incorrectly installed or used.
• Double check battery negative and positive posts before making any connection; a wrong
connection (reverse polarity) will cause the fuse/s to blow and may damage the inverter.
• A small spark (arc) can occur when making the final battery connection, this is most common
when the inverter has not been used for some time. This spark is caused by the inverter’s large
capacitors charging quickly. To minimise this, make the last connection quickly and completely.
• Batteries can be dangerous; follow all battery manufacturer’s instructions and warnings.
• Never operate the inverter without the DC negative input connected direct to the battery and
never install a fuse, circuit breaker or battery switch in the negative supply line (PW150 excepted).
FEATURES
PURE SINE WAVE OUTPUT
There are two different types of inverters, modified sine wave and pure sine wave.
The difference between the two is how closely the output replicates mains power.
Logically it follows that the process used in a pure sine wave inverter is more complex than a
modified sine wave inverter and subsequently more expensive. Most electric appliances operate
unaffected on a modified sine wave and hence they are more common.
Pure sine wave inverters are best for use on medical equipment and sensitive electrical appliances.
They allow you to watch television without static, play your favourite game on an XBoxTM,
Playstation
TM
or WiiTMand run a fluoro, all of which may not operate properly on a modified
sine wave inverter.

CONNECTING THE INVERTER
PW150
The PW150 is fitted with a lead and cigarette plug. Insert the plug into the vehicle’s 12V accessory
socket and turn the inverter on. You may need to turn the vehicle’s ignition to ‘accessory’ to
supply power to the inverter.
PW350, PW600, PW900 & PW1800
It is important to use suitable cable lengths and sizes to get the most out of your inverter. Use of
cable that is too thin or too long will result in voltage drop between the battery and inverter, and
may trigger low voltage warnings and inverter shutdowns. It is recommended to place cable in
corrugated conduit to protect from damage.
The following table lists suitable cable sizes for different cable lengths available from Projecta.

OPERATING INSTRUCTIONS
To operate the inverter turn the inverter On/Off switch to ON (PW150 & PW350) or press the
power button (PW600, PW900 & PW1800). The inverter will beep momentarily while it carries out
a brief self-analysis before supplying power to the AC socket (only on PW150 & PW350). To turn
off, turn the inverter On/Off switch to OFF (PW150 & PW350) or press the power button again
(PW600, PW900 and PW1800).
To help prevent the inverter being overloaded:
1. Ensure appliances are turned off before turning the inverter on.
2. If multiple appliances are being run, turn on one at a time.
MOUNTING INSTRUCTIONS
Pro-Wave inverters are designed for indoor, out of weather use only. During operation, the inverter
should be in a dry, cool and well-ventilated area as close to the batteries as possible, but not in
the same compartment as the batteries. Ensure the inverter is away from flammable materials
and fumes.
The inverter base plate includes a mounting flange for easy mounting (excluding PW150).
If permanently fixed, the inverter should be mounted to a suitable horizontal or vertical panel, with
at least 10cm clearance from the end plates to provide adequate ventilation for the cooling fan.

UNDERSTANDING YOUR POWER REQUIREMENTS
POWER REQUIREMENTS OF YOUR APPLIANCE/S:
All appliances have a rating plate that shows the amount of power (Watts) used or the current
(Amps) drawn under normal use.
The following table shows the maximum combined AC Watts or AC Amps which can be run by
the inverter.

load (Amps)
Some appliances that use an electric motor or transformer may draw up to 10 times their power
rating when first turned on. These are called inductive loads and are the most difficult for the
inverter to run. Contact your appliance manufacturer for further advice.
SUITABLE POWER SOURCE
In order to operate the inverter and supply power to an appliance a suitable 12V DC power supply
is required, typically a vehicle or caravan battery, portable power pack or an independent 12V lead
acid 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) or Cold Cranking Amps (CCA).
Because 12V 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.

TROUBLESHOOTING/FAQ:
Q. Why does the inverter turn itself off?
A. If the inverter’s audible alarm sounds and a fault L.E.D illuminates, this indicates that there is
a fault or error, and the inverter may turn off. Most commonly this would be caused by an
appliance that is drawing too much power (overloading), low battery voltage or voltage drop
due to insufficient size cables or poor connections (refer to 'Understanding your Inverter'
tables, page 7).
Q. The Inverter will not run my appliance even though the appliance draws less power
(Watts) than the size of the inverter?
A. Electrical appliances can be divided into three groups by the way they draw energy (current)
from their power supply. These groups are “Resistive”, “Inductive” and “Capacitive” appliances
or also called “loads”. Some appliances may draw all three types of power.
Resistive Loads such as normal incandescent lights (wire filament) always draw a constant
power (watts) from the power supply, that is a 100 Watt light will draw approximately
100 Watts from the power supply at all times. Resistive loads are the easiest appliances
for an inverter to run.
Inductive Loads such as a refrigerator (Electric Motor) require a large rush of power (surge
current) to start and then usually draw a more constant power once running. Inductive loads
contain coils of wire (motors, transformers, ballasts, solenoids). When the power is first turned on,
these coils of wire draw a large surge current which forms the magnetic flux (magnetic field)
which allows these appliances to work. This magnetic flux is a kind of stored energy.
The most common inductive appliances are: fridges, air compressors, transformers/ chargers,
pumps, power tools and fluorescent lights. These appliances can draw up to 10 times their normal
running power to start up; that is to run a 80W fridge you may need a 600 or 1000 Watt inverter.
Capacitive Loads such as many TV’s or many electronic appliances require a large surge current
to start only when they have not been used for a while. This is often due to large capacitors in the
power supply that must be quickly charged when the appliance is turned on. If the appliance is not
used for a few days these capacitors slowly go flat. Resetting the inverter a couple of times may
allow these appliances to work.
There are some appliances such as large refrigerators, air conditioners and other pump driven
appliances that have extremely high start up currents, because they have an inductive motor
that must start under load. These appliances are not recommended for use with an inverter.
They should be powered by an engine driven generator.
Q. Why does it damage the inverter if the battery leads are reverse-connected?
A. Your inverter uses sophisticated electronics to convert DC battery power to AC mains power.
If you accidentally connect the inverter to the battery incorrectly (reverse polarity) a large current
will be drawn by the inverter which will blow the protection fuse. As this occurs some of the high
current could damage sensitive electronic components. Because of this risk it is important to
always double-check the battery polarity before making any connections.
11
Q. How do I check or change the fuses?
Pro-Wave inverters contain internal fuses and should only be checked or replaced by a qualified
electrical appliance repairer.
THE DC SUPPLY MUST BE DISCONNECTED BEFORE ANY REPAIR, THEN TURN THE ON/OFF
SWITCH OF THE INVERTER “ON” TO DISCHARGE THE CAPACITORS.
Q. Why does the fan only operate sometimes?
A. Pro-Wave inverters feature a temperature controlled automatic cooling fan that only operates
when needed. This allows the inverter to run very quietly for most of the time.
Q. Can I run laptop computers and other sensitive electrical appliances?
A. Yes. Pro-Wave’s pure sine wave output is suitable for medical equipment and sensitive electrical
appliances. They allow you to watch television without static, operate computers and gaming
consoles and run fluorescent lights.
