RS SERIES INVERTERS
REDARC Pure Sine Wave Inverters produce a pure sine wave output. This means that the power output
from a REDARC Pure Sine Wave Inverter is not only the same as the mains supply, it’s often better.
The R-12-1000RS-NA and R-12-1500RS-NA are compliant for residential and industrial applications
whereas the R-12-2000RS-NA and R-12-3000RS-NA are compliant for industrial applications only.

CAUTION
1. This appliance is not intended for use by
persons (including children) with reduced
physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they are
supervised or have been instructed on how to
use the appliance by a person responsible for
their safety. Children should be supervised to
ensure that they do not play with the appliance.
2. Do not operate the inverter with damaged or
substandard wiring. Selecting the wrong cable
or fuse size could result in harm to the installer
or user and/or damage to the inverter or other
appliances installed in the system. The installer
is responsible for ensuring that the correct
cable and fuse sizes are used when installing
this inverter. Refer to Section 2.2.4 (page 19)
for more information.

WARNINGS AND SAFETY INSTRUCTIONS
3. Ensure that all the DC connections are tight — torque between 9to10 ftlbf (11.7to13Nm). Loose
connections could result in overheating and can be a potential hazard.
4. Some components in the inverter can cause arcs and sparks. Do not put batteries, flammable
materials, or anything that should be ignition-protected around the inverter. Doing so may result in fire
or explosion. Be extra cautious so as 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.
5. 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.
6. 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 flood the
eye with running cold water for at least 10 minutes and seek medical assistance immediately.
7. NEVER smoke or allow a spark or flame in the vicinity of a battery. This may cause the battery to
explode.
8. 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 fire in the case of a short circuit. Only use high quality copper cable and
keep the cable length short, refer to Section 2.2.4 (page 19) 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
will void warranty.
• Do not operate appliances that may feed power back into the inverter. Damage to the inverter may
occur as a result.
• Ensure that the frequency output of the inverter matches the frequency requirements of all
appliances and equipment to be used with the inverter. Attempting to use appliances that requires
an AC frequency different to the inverter output may result in damage to your appliances. Output AC
frequency is dip switch selectable, see Section 2.1.3 (page 14).
• All RS Series Inverters are suitable for indoor use only.
• The direction of fan air flow must be horizontal.

2.2.3 Chassis Ground
Use 16 AWG (1.5mm²) or a thicker cable to connect the vehicle earth or chassis ground. Perform this
connection prior to any other connection.
2.2.4 DC Input Connection
Prior to installation:
• The cable and fuse sizes in Table 2.2.4.1 are recommended for connection between supply battery
and inverter. The DC supply cables should be as short as possible and no longer than the values
shown in Table 2.2.4.1.
• The size of the cable should be thick enough to maintain a voltage drop of less than 2% when
carrying the maximum input current. This will help prevent frequent low-input voltage warnings and
shutdown.

3 INSTALLATION
3.1 Mounting
Install the inverter in a well-ventilated area with reasonable clearance, avoid installing 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.
The power inverter should be used in an environment that meets the following requirements:
1. Dry — Do not allow water to drip on or enter into the inverter. Do not allow moisture to
condense on the inverter.
2. Cool — Ambient air temperature should be between 32°F (0°C) and 104°F (40°C).
3. 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.
4. Ventilated — Keep the inverter at a distance (at least 1" (25mm) away from surrounding objects.
Ensure the vents on the rear and the bottom of the unit are not obstructed.
5. Dust — Do not install the inverter in a dusty environment where the dust can enter into the unit both
when the fan is operating and not operating.
6. Fused – A fuse must be fitted between the battery and the inverter, positioned as close to the
battery as possible.
7. Do not mount the inverter where it will be exposed to the gasses produced by the battery.
These gasses present a risk of explosion and are very corrosive, prolonged exposure may
damage the inverter.
WARNING
RISK OF ELECTRICAL SHOCK. DO NOT EXPOSE THE INVERTER TO RAIN, SNOW, SPRAY, BILGE OR DUST. DOING SO
MAY RESULT IN DAMAGE TO THE INVERTER OR OTHER APPLIANCES INSTALLED IN THE SYSTEM OR RESULT IN
ELECTRIC SHOCK OR FIRE.
RISK OF ELECTRICAL SHOCK. DO NOT DISASSEMBLE THE INVERTER - THE INTERNAL CIRCUITRY CONTAINS
HAZARDOUS VOLTAGES. ATTEMPTING TO SERVICE THE UNIT YOURSELF MAY RESULT IN ELECTRIC SHOCK OR FIRE
AND WILL VOID THE UNIT WARRANTY.

3.2 Ventilation Fan
The fan is load and temperature controlled and will operate when the AC Power Consumption and
temperature requires it. The fan will also occasionally come on when no load is connected. Ensure that
the fan is not obstructed and the inverter is at a distance of at least 1" (25mm) from surrounding objects.
