1. Overview
The Ring 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.

5. Safety
This manual contains important information about the operation of this product. Failure to comply with
the instructions can cause electric shock, fire or serious injury. Responsibility will not be accepted for
damage to persons or property caused by failure to follow the operating instructions.
- Installation should be carried out by a qualified electrician
- Do not expose the unit to moisture or flammable materials
- Do not remove the unit cover, dangerous voltages are present
6. Installation & Setup
Location
This inverter is for indoor use only and should be installed in a well ventilated, cool, dry environment.
- To prevent overheating, do not install where ventilation openings may be obstructed
- Allow 10cm all around the inverter casing to ensure adequate ventilation
- Do not install near fuel tanks or within battery compartments
Battery Connections
Connect the inverter to the battery using the supplied battery cables and terminals.
1. Ensure that the inverter power on/off switch is in the OFF (O) position.
2. To protect inverter terminals against short circuit, protective covers should be fitted where provided.
3. Attach the black (-) cable to the black (-) terminal on the rear face of the inverter and to the black (-)
terminal on the battery
4. Attach the red (+) cable to the red (+) terminal on the rear face of the inverter and to the red (+)
terminal on the battery
5. To further protect against short circuit, it is recommended an in-line fuse (F1) be fitted near the
positive battery post.
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.

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.

Earth Connection
Ensure the inverter is earthed by connecting a cable from the inverter earthing bolt
within the installation (normally the vehicle chassis).

CAUTION
Do not operate the inverter without connecting it to ground, otherwise a fault
condition may present an electric shock hazard.
Earth Leakage Protection
When the inverter is used to power 230V socket outlets, which are a permanent part of the installation, a
Residual Current Device (RCD) should be fitted to provide protection in the event of a fault. The diagram
below shows recommended wiring for 230V sockets fitted with an integral RCD. Note: In order for an
RCD device to trip effectively when used in a vehicle, the neutral output from the inverter should be
linked to the earthing system of the installation. Fig3 below shows a recommended installation.

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 (RINVFRM)
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 (RINVLCD)
1. Connect 6 metre extension lead to display port J on 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
(RINVCM) should be fitted as shown in Fig4

Cables provided
with inverter
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 K on 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
7. 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
8. 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.
