RS3 Pure Sine Wave Inverter
PRODUCT FUNCTION
The REDARC RS3 range of Pure Sine Wave Inverters have
been designed to provide safe, efcient, and reliable 230VAC
power for your electronic devices in remote environments.
Built with safety in mind, the RS3 Inverters feature a residual
current circuit breaker with overcurrent protection (RCBO).
This will safely and effectively shut-down power to a
connected load in an over current or short circuit event whilst
also protecting against electrocution, making it a safe and
reliable choice for a wide range of applications.
Available in 12V and 24 V input variants, the RS3 range is
suitable for installations in a range of applications including
caravans, camper trailers, motor homes, truck sleeper cabs,
4x4's and commercial vehicles.
RS3 Inverters are also equipped with an inbuilt Automatic
Transfer Switch (ATS) to automatically switch from battery
power to mains power when available.
Discover power and convenience on the go like you've never
experienced before with 1200W, 2000 W, 3000 W models
available to power appliances such as laptops, power tool
battery chargers, coffee machines, kettles, induction cookers
and toasters.

potential hazard.

Warnings and Safety Instructions | 5
Some components in the inverter can cause arcs and sparks. Do not put batteries, ammable materials,
liquids, or anything that should be ignition–protected around the inverter. Doing so may result in re or
explosion.
Be extra cautious to reduce the risk of dropping a metal tool onto a vehicle battery. Doing so might cause
the battery to spark or might short-circuit the battery or other electrical parts that may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
battery. A battery can produce a short-circuit current high enough to weld a ring or the like to metal,
causing a severe burn.
If battery acid contacts your skin or clothing, remove the affected clothing and wash the affected area of
your skin immediately with soap and water. If battery acid enters your eye, immediately ood the eye with
running cold water for at least 10 minutes and seek medical assistance immediately.
NEVER smoke or allow a spark or ame in vicinity of battery. This may cause the battery to explode.
Batteries are capable of providing very large currents in the case of a short circuit. A fuse must be installed
on the positive supply cable as close as practical to the battery. Failure to do so provides inadequate
protection against re in the case of a short circuit. Only use high quality copper cable and keep the cable
length short, refer to Section 3.1 (page 14) for more information.
NOTICE
Upon receipt, examine the box for damage. If you have found any damage on the box, please notify the
company you purchased this unit from.
Install the inverter in a well-ventilated area with reasonable clearance. Do not install the inverter in a
zero-clearance compartment or obstruct the ventilation openings. Doing so may result in the inverter
overheating and ultimately damage the inverter.
Reverse Polarity connection will blow the internal fuse and may damage the inverter permanently and could
void the warranty.
Do not operate appliances that may feed power back into the inverter. Damage to the inverter may occur
as a result.
The RS3 Inverters are tted with RCBO, which incorporates both a residual current device as well as a
circuit breaker. The RS3 Inverters comply with AS/NZS 4763 standard and can be used to power xed
wiring in accordance with AS/NZS 3001 when installed by a licensed electrician. A proper ground bond is
required for the RCD to work as intended, see page18 for more information.
Ensure that the frequency output of the inverter matches the frequency requirements of all loads attached
to the inverter. Attempting to use appliances that requires an AC frequency different to the inverter output
may result in damage to your appliances.
All RS3 Series Inverters are suitable for indoor use only.
When the ATS is passing grid power through the load(s), the RCD and over-current protection must be
provided by the 'shore power' supply (refer to Section 1.4 (page 10)).
When the ATS is passing through AC power from the AC Input connection, the integrated M.E.N.
connection (Main Earth Neutral - required for correct operation of the RCD) is not in circuit. The external
AC supply must provide the safety mechanism for the connected loads – consult a qualied electrician.

PIN 3 (N.C), PIN 4 (COM) AND PIN 5 (N.O)
Pins 3, 4 and 5 are contacts of a Form C relay circuit that can be used to connect remote status
indicators such as LED's. The relay is rated up to 30VDC / 2 A. When the Inverter is in a "FAULT"
condition, the relay will switch Pin 4 (COM) from Pin 3 (N.C) and make contact with Pin 5 (N.O).
This relay is switched when a fault condition occurs including:
Input Over / Under Voltage
Output Short Circuit / Overload
Under / Over Temperature
For example, the installer may want to connect LED indicators if the Inverter is operating normally or in
a fault condition. To do this, the installer may connect Pin 4 (COM) to battery positive (BAT+), a "OK"
LED to Pin 3 (N.C) and a "Fault" LED to Pin 5 (N.O).

3 INSTALLATION
3.1 CABLE AND FUSE REQUIREMENTS
WARNING: When exposed to high temperatures (such as found in engine bays and adjacent
exhaust components), use suitably rated high-temperature cables and conduits. Avoid routing cables
over sharp edges or where moving parts of the vehicle could adversely affect the cable. Conduit
should also be used to protect cables against physical damage in vulnerable locations.
CAUTION: Batteries are capable of supplying very large currents. Fuses must be placed as close as
possible to the positive battery terminal to protect the cable from damaging currents — failure to do so
could cause re or personal injury.
NOTICE: A cable size that is below the specication for the installation length, will result in an increased
voltage drop when the inverter is under load. Common symptoms of incorrect cable size may include poor
surge capability, low input voltage warnings, shutdowns, and overheating/melting of the cable.
For cable connections from the Inverter to the supply batteries refer to Table 1 and Table 3 for the
correct cable size; and refer to Table 2 and Table 4 for correct fuse sizes.
REDARC recommend for the cables to be short as possible being no longer than the values
in Table 1 and Table 3 and to apply heatshrink to the DC Input cables.
The cable between the Inverter and battery must be a large enough gauge to prevent excessive voltage
drop over its length. As voltage drop occurs between battery positive and ground, the total cable install
length of positive and negative cable combined must be considered (refer to Figure 7).

The RS3 Inverter should be used in an environment that meets the following requirements:
The Inverter must be mounted on a structural surface using all four mounting holes with
appropriate M6 fasteners.
Dry—Do not allow water to drip on or enter into the inverter.
Cool—Ambient air temperature should be between 0°C to 40°C (32°F to 104°F).
Safe—Do not install the inverter in a battery compartment or other areas where volatile fumes may
exist, such as fuel storage areas or engine compartments.
Ventilated—Keep the inverter at a distance (at least 25 mm (1")) away from surrounding objects.
Ensure all ventilation openings are not obstructed.
Dust free—Do not install the inverter in a dusty environment where the dust can enter into the unit,
and especially not drawn into the product when the cooling fan is working.
Fused—Batteries can supply very large currents; a fuse must be tted between the battery and the
inverter. The fuse must be located as close as possible to the battery's positive terminal to protect
the cabling. Use the recommended cable and fuse sizes (see page14).
Close to batteries—Avoid excessive cable runs between battery and inverter to reduce the voltage
drop across the cable. For safety reasons however, even when installed in a well
ventilated area the inverter should not be installed within 300 mm (11.8") of the battery. The inverter
must never be installed within the same enclosed compartment with the battery.
Do not mount the inverter where it will be exposed to the gasses produced by the battery.
These gasses are very corrosive, and prolonged exposure will damage the inverter.
