Instructions
Retain these instructions for future reference

1. Overview
The Pure Sine Wave (PSW) inverter provides a 230V supply which closely replicates the domestic
mains supply. This makes it ideal for powering more sensitive equipment which may not be compatible
with traditional Modified Sine Wave (MSW) inverters.

CAUTION
There may be sparks produced when making battery connections, ensure no
flammable materials are present. Incorrect connection of cables to the battery (reverse
polarity) may damage the unit and is not covered by the warranty.

Dual Battery System
For heavy duty applications a secondary battery can be fitted to increase the inverter running time. An
additional relay may also be fitted to allow this battery to be charged from the vehicle alternator when the
vehicle engine is running, Fig2 shows an example installation.

It is recommended the inverter is wired and tested by a qualified electrician
Remote Mounting LCD Display (1000/2000/3000W Models)
For installations where the inverter may be inaccessible, the LCD display can be removed from the
inverter and mounted remotely using the optional LCD Frame Kit (WINVFRM)
1. Ensure that the inverter power on/off switch is in the OFF (0) position.
2. Remove 2 x screws holding LCD in position
3. Pull LCD forwards and unclip data connector from circuit board
4. Connect 6 metre extension lead to circuit board
5. Fit blanking plate and fix with 2 x screws, a slot is provided for cable to exit
6. Fix LCD into mounting frame using 2 x screws
7. Fit frame where display is required and attach 6 metre cable to rear
8. Snap fit endplates to cover screw fixings
9. Turn the power on/off switch to the ON (I) position.
10. Inverter can now be controlled remotely from the LCD display

Adding an LCD Display (600W Model)
An LCD display can also be added to models without this function by using the optional LCD Display &
Frame Kit (WINVLCD)
1. Connect 6 metre extension lead to display port Jon inverter
2. Fit frame where display is required and attach 6 metre cable to rear
3. Snap fit endplates to cover screw fixings
4. Turn the power on/off switch to the ON (I) position.
5. Inverter can now be controlled remotely from the LCD display
Current Sensor Installation (optional)
To enable monitoring of the input current and hours remaining function, the optional current sensor
(WINVCM) should be fitted as shown in Fig4
1. Using black battery cable supplied with inverter, attach one end to battery(-) terminal and other
end to batt(-) terminal on Current Sensor
2. Using red battery cable supplied with inverter, attach one end to battery(+) terminal and other
end to inverter(+) terminal
3. Now connect cables 1-4 (supplied with current sensor) as shown in Fig4
1- Load(-) cable, negative connection from inverter to sensor
Use 1x4AWG cable for 600/1000W models
Use 2x2AWG cable for 2000/3000W models
2 - Comms cable, data connection from sensor port Kon inverter to current sensor
3- +12V Power cable, 12V power supply to sensor
4- Temperature sensor cable, temperature compensation for a more accurate current reading

5. General Information
Continuous & Surge Power
A Continuous rating is the amount of power the inverter can handle for a number of hours without
overloading. The Surge rating is a brief burst of power the inverter can provide to help start certain types
of load.
Loads Requiring Surge Power
The power rating shown on most electrical appliances is a continuous rating but some appliances require
up to five times this power for a brief period in order to start operating. This needs to be considered
when rating the inverter to avoid overloading it.
When using a microwave oven it should also be noted that the electrical power required from the supply
is around 50% higher than the actual cooking power of the microwave.
Typical Typical Surge
Example Appliance Rated Power Power Required (<1 sec)
Electric Drill 500W 1000W
800W Microwave Oven 1200W 2400W
Angle Grinder 900W 2700W
Portable Air Compressor 200W 700W
Laser Printer 500W 2500W
6. Operation
Switching On
1. Ensure that the inverter power on/off switch is in the OFF (0) position.
2. Plug the appliance into the AC output socket on the inverter, ensuring it does not exceed the
maximum output power of the inverter
3. Turn the power on/off switch to the ON (I) position.
4. The Power indicator will illuminate green and mains power will be available from the AC output
socket(s). On models fitted with a display the LCD screen will also illuminate.
7. LCD Display & Indicators
Where fitted the LCD display provides additional information to help monitor and manage power from
the inverter.
