5. HEALTH AND SAFETY INFORMATION
5.1 GENERAL SAFETY INSTRUCTIONS FOR POWER TOOL USE
Warning! Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future reference.
The term “power tools” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust
or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not
use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the
power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or
entangled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
f) If operating a power tool in a damp location is unavoidable, use a residual current
device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury.
b) Use personal protective equipment Always wear eye protection. Protective equipment
such as a dust mask, non-skid safety shoes, hard hat or hearing protection use for
appropriate conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position before
connecting to power source and/or battery pack, picking up or carrying the tool.
Carrying power tools with your finger on the switch or energising power tools that have the
switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a
key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
– 6 –
5. HEALTH AND SAFETY INFORMATION
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing
away from moving parts. Loose clothes, jewellery or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of dust collection can reduce
dust-related hazards.
h) Do not let familiarity gained from frequent use of tools allow you to become
complacent and ignore tool safety principles. A careless action can cause severe injury
within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your application. The
correct power tool will do the job better and safer at the rate for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
c) Disconnect the plug from the power source and/or remove the battery pack, if
detachable, from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow persons
unfamiliar with the power tool or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
e) Maintain power tools and accessories. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the power tool’s
operation. If damaged, have the power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to be
performed. Use of the power tool for operations different from those intended could result
in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for safe handling and control of the tool in
unexpected situations.
5) Service
a) Have your power tool serviced by a qualified repair person using only identical
replacements parts. This will ensure that the safety of the power tool is maintained.

8. PREPARATION
8.3 GROUNDING CONNECTION –
FIG. 5
WARNING! Before using this equipment you
must provide a ground connection to the
inverter.
On the casing of the inverter is an earthing terminal
(14). This earthing terminal is connected to the
case of the inverter and also to the earth terminal
of the AC output socket. The use of this earthing
terminal will depend on your particular installation.
In any installation, heavy duty, green+yellowinsulated wire should be used for this connection.
In a stationary land based installation, the earth
terminal should be connected to a metal earthing
stake driven into the ground to a depth of 1.2M or
more, If the battery system powering the inverter
does not have a connection to ground, one of the
battery terminals (commonly the negative terminal)
should also be connected to the earthing stake.
In a vehicle where the inverter is wired directly to
the battery, the earth terminal is simply connected
to the vehicle chassis. If the inverter is to be used
in a vehicle on a temporary basis and will be
powered via the cigarette lighter socket in the
vehicle, the earth terminal should be connected via
a short link to either the negative or positive DC
input terminal of the inverter, depending on whether the vehicle has a negative or positive chassis
connection. However, when using the inverter to power equipment used outside the vehicle, an
earthing stake should also be used, as described above.
In a boat, the grounding terminal should be connected to the existing grounding system, which
may be the hull of the craft, or a network of ground wires.
Note: The grounding terminal of the AC outlet is connected to the neutral terminal. This is the
same as a standard household power point where the neutral line is bonded to grounding and
there is normally no voltage between them.
5 FIG.
(14)
(14)
8.4 CHASSIS EARTHING
The chassis earthing lug should be connected to an earthing point, which will vary depending
on where the power inverter is installed. In a vehicle, connect the chassis ground lug to the
chassis of the vehicle. In a boat, connect to the boat’s grounding system. In a fixed location,
connect to grounding.

9. OPERATION
9.1 230V AC OUTPUT – FIG. 6
Most electrical tools, appliances and equipment
have a rating label indicating the power
consumption in amps or watts. Calculate the power
consumption of these items you will be using
simultaneously, keeping the rating under the
inverter’s maximum capacity.
Note: If the rating is stated in amps, multiply
the value by the voltage (230V) to determine
the wattage.
− Place the inverter in a well ventilated area for
optimum cooling.
− Plug the device to be powered into the AC
outlet (1). Position the ON/OFF switch (2) to
the ‘ON’ position.
FIG.
9.2 5V DC USB OUTPUT – FIG. 7
− Insert USB plug (3). Position the ON/OFF
switch (2) to the ‘ON’ position.
The current draw will vary depending on the load
being placed on the battery. The battery life will
also vary depending on the age and condition of
the battery. Ensure the vehicle is started and run
regularly to avoid starting problems due to a flat
battery. However, do not start the engine while
running the inverter.
• Switch off the inverter • Start the engine • Switch on the inverter.
FIG.
9.3 DISRUPTED VOLTAGE WARNINGS AND ALERTS
If the battery voltage drops significantly an audible alarm will sound. When the battery voltage
reaches a low level the LED will illuminate red and the unit will automatically shut off. Switch the
unit off and unplug the load. The battery will need recharging before using again.
The typical vehicle battery has a minimum operating time of 1 to 2 hours, depending on the
current use of the load being driven. We recommend that the operator start the vehicle every hour
to recharge the battery system. This will prevent unexpected shut downs of equipment and will
ensure that there is always sufficient battery capacity to start the engine.
The inverter circuitry constantly monitors the following hazardous conditions:
A. Low battery voltage – this condition is not harmful to the inverter, but could damage the
power source. An audible alarm is sounded when input voltage drops to 10.5 volts. The
inverter shuts down when input voltage drops to 10.0 volts. When the condition is corrected
(i.e. alternator charges battery), the unit may be restarted.
B. Short circuit – reverse polarity or short circuit condition of the load will usually result in
opening of the short circuit protection.
C. High temperature – when the temperature of the internal heat sinks reaches 65°C (150°F),
the solid state temperature sensor located in the power inverter will automatically shut down
the unit. Once allowed to cool, it may be restarted.
Note: The alarm may sound momentarily when the unit is being connected to, or disconnected
from, the power source. This is normal and does not indicate any problem.
For further information, consult the troubleshooting guide on page 15.

9. OPERATION
9.4 FUSE REPLACEMENT – FIG.8
− Ensure the unit is disconnected/switched off.
− In the event of the fuse blowing, remove the
12V DC car cigarette lighter
− 12V DC battery connector leads (12) (model
28814 IN200/USB only).
− Pull out the blown fuse (16) and replace with a
fuse of the same rating and design determining
the cause of the fault prior to re-using.
9.5 OPERATING TIPS
Resistive loads, such as incandescent lights, are
the easiest for the inverter to drive, though larger
resistive loads, such as electric stoves or heaters,
require more power than the inverter can deliver continuously.
Inductive loads, such as TV’s and stereos (any device with a coil or a transformer in it) require
more current to operate than a resistive load of the same power rating. Induction motors (motors
without brushes), as well as some televisions, may require 2 to 6 times their power rating to start
up. This condition may require the repeated on and off switching of the inverter power switch
several times in order to get them started.
The most demanding appliances are those that start under load, i.e. compressors and pumps.
Since motor and television characteristics vary widely, only experimentation will determine if a
specific load can be started and how long it can be run.
There are no standards for ‘surge power’ partly because it can not be simply represented by a
simple, single number. Though a 300W power inverter can provide power up to 600W for a short
period, experimentation is the only method of determining whether an inverter can handle the
surges generated by a particular load.
Important: The power inverter will not operate most appliances designed to produce heat, such
as hair dryers, coffee makers, irons, heaters, and toasters. The current use of most of these
exceeds rated power watts far beyond the capacity of these units. The inverter may be used either
while the engine is running or turned off, however, the inverter should not be operated while the
engine starting, since the battery voltage can drop substantially during cranking. The power
inverter draws less than 1.3 ampere from the battery when it is not supplying power to the load. In
most cases, the power inverter may be left connected to the battery when it is not in use, since it
draws so little current. If the vehicle will not be used for several days, disconnect the power
inverter from the battery.
