OVERVIEW
The Ring Pure Sine Wave (PSW) inverter provides a 230 volt 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.

3. 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
4. INSTALLATION
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 are provided. Note:- for rubber
versions these should be slid onto the cables prior to fixing to rear of inverter
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.

8pp A5 (PSW) UK Full Handbook v4.indd 3 07/04/2014 09:48
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.
Fig2 – Example dual battery system
Earth Connection
Ensure the inverter is earthed by connecting a cable from the inverter earthing bolt (10) to a suitable earth
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.

To make installation simpler and provide a more integrated solution, some models are provided with internal
RCD protection and screw terminal connections. Fig3 below shows an example installation

Note:- It is recommended the supplied fork terminals are used for a more secure connection
4. Re-fit cover plate, fully tighten glands and check cables cannot move (see Fig5)
AC Output Connections - models without integral RCD
An RCD device can still be used on models without this feature integrated into the inverter. The diagram
below shows recommended wiring for 230V sockets 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. Fig5 below shows a recommended installation

5. GENERAL INFORMATION
Continuous and 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 surge ratings

Angle Grinder 900W 2700W

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)
7. INDICATORS & WARNINGS

Switch inverter off, re-charge battery then
switch back on. Check battery voltage is
correct for inverter model i.e. 24volt battery >
24volt inverter.
Disconnect all loads, switch inverter off then
back on. If overload indicator is now off:
1. Total load exceeded inverters continuous
rating.
2. Appliance startup current exceeded
inverters surge rating.
3. A connected appliance may have an
electrical fault, test appliances before
re-connecting
Check inverter cooling fans are working.
