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 minimize 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.

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,
PlaystationTM, or WiiTM, and run a fan, all of which may not operate properly on a modified sine wave inverter.

FULLY ISOLATED DESIGN
Safety is paramount around 240V and in particular with inverters which is why Projecta fully electrically isolates the DC (and therefore battery posts, vehicle chassis, etc) from the 240V AC circuit.

DESIGNED TO AS4763
Designed in accordance with Australian Standard AS4763: 2011 – Safety of Portable Inverters.

REMOTE CONTROL DISPLAY
The PW2100 can connect to the included remote (P/No. PWREMOTE-1) which will allow the inverter to be turned on/off remotely and monitor the battery voltage(V), load(W) and faults. Ideal for use in 4WD, caravans, motor homes and boats.

CONNECTING THE INVERTER

PW2100-24
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 supplied cable sizes for Projecta Pro-Wave inverters:

Supplied Cable

PW2100-24| 1.1m, 35mm²

1. Prepare all cable ends with cable lugs.
2. Install a circuit breaker or high current fuse and fuse holder in the positive line as close to the battery as possible. The following fuses are available from Projecta: PW2100-24: IFB-150 (150A fuse and holder)
3. Make sure the inverter On/Off switch is turned OFF.
4. Connect the cables to the DC input terminals on the rear of the inverter. The red terminal is positive (+) and the black terminal is negative (-).
5. Connect the positive cable to the inverter and battery positive terminals.
6. Connect the negative cable to the inverter and battery negative terminals.
7. The inverter is earthed through the negative DC input cable. Additional earthing can be made by connecting an insulated wired from the chassis-ground terminal at the rear of the inverter to the vehicle’s chassis or any other ground point.

OPERATING INSTRUCTIONS

To operate the inverter press the power button . To turn off, press the power button again.
To help prevent the inverter being overloaded:

1. Allow the inverter to complete its start-up process when switched ‘ON’.
2. Ensure appliances are turned off before turning the inverter on and;
3. 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.
If permanently fixed, the inverter should be mounted to a suitable horizontal or vertical panel, with at least 50cm clearance from the end plates to provide adequate ventilation for the cooling fan.

1. Press the power switch on the unit to turn the unit off.
2. Remove all AC loads or let the unit cool down for about 15 minutes.
3. Press the power switch on the unit to turn the unit on.

Input Voltage
The input voltage limits are shown in the following table.

battery from being over-discharged.
High voltage shutdown| Voltage is 30.4V (±0.6V)| The unit shuts down to protect itself from excessive input voltage. Note: Although this incorporates over-voltage protection, it can still be damaged if input voltage exceeds 31.0V.
Unit restarts after low voltage shutdown| 24±0.6V| The unit will not restart unless the battery voltage is acceptable for running the load.

REMOTE CONTROL
An optional remote can be purchased for the PW2100: P/No. PWREMOTE-1.
To install the remote control, insert the plug into the remote input socket on the rear panel.
The remote has the ability to turn the inverter on and off remotely and indicate when the inverter is on.

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.

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 24V DC power supply is required, typically a vehicle or caravan battery, portable power pack or an independent 24V 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 24V 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.

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.
