Introduction
The Ring PowerSource is an electronic device that converts a low voltage 12v DC current from a
battery, or other source and provides 230-240v AC current.
Special attention should be made to CAUTION statements in this users manual.
CAUTION statements identify conditions or practices that could result in damage to your
PowerSource or to equipment that you are using with it.
CAUTION
• When connecting the PowerSource directly to a battery or other power supply ensure that you
observe correct polarity (Ensure the red ‘+’ positive lead is clamped to the positive battery terminal
and the black ‘-‘ negative lead is attached to the negative battery terminal.
• Do not exceed the maximum input voltage (15v DC).
• Do not remove the protective cover under any circumstances, only by a qualified electrician.
• Improper use of the PowerSource can cause damage to property and possible harm to the user.
Power Supply
The battery or power supply must provide between 10.5 and 14.5v DC (a car battery will usually pro-
vide this) and must be able to provide sufficient current to operate the load (the item you require to
power).
The power supply may be a battery or a regulated DC power supply. In order to find out if your power
supply is big enough, divide the power consumption of the load (in Watts) by the voltage (12v DC in
the case of the PowerSource) this will give you the current (in amps) that the power supply must
deliver.
EXAMPLE: Load is rated at 100 watts
Power supply must be able to deliver: 100 / 12 = 8.3 amps
CAUTION THE RINV500 MUST ONLY BE CONNECTED TO BATTERIES OR REGULATED POWER SUPPLY
WITH A NOMINAL DC OUTPUT VOLTAGE OF 12 VOLTS. THE POWERSOURCE WILL NOT OPERATE ABOVE
15 VOLTS.
CAUTION DO NOT USE WITH POSITIVE GROUND ELECTRICAL SYSTEMS IF USING DIRECTLY FROM
VEHICLE BATTERY.
The majority of modern cars have negative ground electrical systems. If you are in any doubt, please
check with a qualified auto electrician or your local vehicle main dealer.
Connecting to power supply
RINV500
Switch off the RINV500 PowerSource. The RINV500 PowerSource comes complete with two cables
that are to be connected onto the back of the PowerSource using the sockets. Do not over tighten
and check no wire is exposed. Observe correct polarity. (Red + positive, Black - negative). The other
end with the crocodile clips are then clamped to the battery terminals again be sure to observe the
correct polarity.
Connecting your PowerSource
Connect the PowerSource input to the vehicle/leisure battery using the cables supplied. Ensure the
load requirements are within the parameters of the PowerSource output; plug your appliance into the
socket of the PowerSource. Ensure the PowerSource is switched off prior to plugging any accessories
and connecting to battery or power supply.
CAUTION Some rechargeable products have a charger that is designed to be plugged directly into
mains 240v sockets. These can damage the PowerSource. When first using a rechargeable product,
monitor its temperature for 10 minutes to ensure overheating does not occur.
Fuse replacement
RINV500 – 35amp (x2) Internal blade fuses.
Please consult a qualified electrician to replace any fuses.
Positioning of PowerSource
The following points should be noted:
• The PowerSource is not waterproof.
• The PowerSource should be placed on a ventilated flat surface.
• Do not put the PowerSource on or near direct heat or expose to sunlight.
• Do not place the PowerSource in or around flammable environments.
Operating tips
NOTE: The PowerSource is not designed to run products that provide heat, such as hair dryers or
irons.
Protective features
Low battery alarm – An alarm will sound when the voltage from the battery drops to 10.6v DC. This
indicates that the battery the PowerSource is connected to will require recharging. (If connected to a
vehicle battery, starting the vehicle engine should be sufficient) The PowerSource will automatically
shutdown if its voltage is allowed to drop to 10v or below.
Over voltage protection – The PowerSource will automatically shutdown if the input voltage
exceeds 15v DC.
Reverse polarity protection – Reverse polarity (incorrect battery connection) may result in the blow-
ing of the internal blade fuses. If this occurs immediately disconnect the battery. The internal blade
fuses will need to be checked by a qualified electrician if the PowerSource does not continue to work.
Overload protection – The PowerSource will automatically shut down if the continuous power draw
exceeds its maximum rating of the PowerSource.
Temperature protection – If the temperature of the internal heat sink reaches >65˚C the
PowerSource will shut down automatically. Allow the PowerSource to cool before using again.
