1. SAFETY
DANGER! - Beware, lead-acid batteries generate explosive gases during normal battery operation.
Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush immediately with cool clean running
water for at least 15 minutes and seek immediate medical attention.
DO NOT smoke or allow a spark or flame in the vicinity of the battery or engine.
If the battery terminals are corroded or dirty, clean them before attaching the clips.
WARNING! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow them to
touch the battery terminals.
Before attaching to battery, remove personal metallic items such as rings, bracelets, necklaces and watches. A lead acid battery can produce a
short-circuit current which is high enough to weld such items to the vehicle and cause severe burns.
Keep children and unauthorised persons away from the working area.
WARNING! DO NOT use on any vehicles other than those with 12Vdc systems.
WARNING! For delicate items such as laptops, an anti-surge device is recommended.
DO NOT connect to any AC power source.
DO NOT dismantle. The inverter must be checked by qualified service personnel only.
DO NOT get inverter wet or use in damp or wet locations or areas where there is condensation.
DO NOT use the inverter for any purpose other than for which it is designed.
DO NOT pull the cables or clips from the battery terminals.
DO NOT operate the inverter if damaged.
DO NOT connect to a positive earthed system. Ensure you have the polarity correct before connecting, red clip to positive (+) battery terminal
and black clip to negative (-) battery terminal.
Before connecting ensure nothing is plugged into the inverter, and the inverter is switched OFF.
WARNING! Inverters become hot during use.
When not in use store inverter in a safe, dry, childproof location.

4.1. Power Source Requirements.
4.1.1. The inverter must be connected to a 12Vdc negative earth system. DO NOT use with a positive earth system.
4.1.2. The power source must be capable of providing between 11.0V and 15.0V and able to supply the necessary current to operate the load.
The alarm will sound if the voltage is less than 11V.
4.2. Connecting Battery Clips or Vehicle Accessory Plug to Inverter.
4.2.1. To attach the Battery Leads remove the terminal screws on the rear of the inverter (fig.1 or 2)
4.2.2. Attach the black battery lead ring connector to the Negative (-) terminal screw on the inverter, and tighten.
4.2.3. Attach the red battery lead ring connector to the Positive (+) terminal screw on the inverter, and tighten.
4.2.4. Check that the battery leads are secure.
4.3. Connecting Vehicle Accessory Socket Power Source.
4.3.1. To connect the vehicle accessory plug, attach the ring connectors to the terminal screws as in section 4.2.
4.3.2. Plug the accessory plug into the vehicle accessory socket.
Note: some vehicles will require the ignition to be switched to the accessory position to supply power to the accessory socket.
NOTE! Vehicle accessory sockets are generally fitted with a 15A to 20A fuse. To avoid overload and blowing the fuse, if the
device to be connected exceeds 200W then use the battery clips instead of the vehicle accessory plug.
4.4. Connecting to Battery Terminals.
NOTE! Check the battery is 12Vdc. DO NOT use with a 6V or 24V battery
4.4.1. Ensure battery terminals are clean, if necessary clean away any corrosion.
4.4.2. Check to make sure the inverter is turned OFF and no flammable fumes are present.
4.4.3. Clip the red (+) battery clip to the red (+) terminal post on the battery.
4.4.4. Clip the black (-) battery clip to the black (-) terminal post on the battery.
4.4.5. Check all connections are secure.
4.5. Connection to Load.
NOTE! Most electrical appliances, tools etc, have a rating plate indicating the power consumption in amps or watts. Use
these ratings to ensure you remain within the inverters maximum capacity. If the rating is shown in Amps, multiply
the value by the voltage (230V) to determine the wattage.
4.5.1. Ensure that the inverter is switched OFF. Plug the equipment you wish to use into the inverter 3 pin socket or into the USB port as
required (fig.3).
4.5.2. Make sure the load does not exceed the wattage rating of the inverter.
4.5.3. Switch the inverter on, check that everything is working and the green LED is lit.
WARNING! DO NOT connect the inverter to any AC distribution wiring or any AC load circuit in which the neutral conductor is connected
to ground (earth).
NOTE! Some rechargeable devices do not operate well with a moderated sine wave inverter. They only operate from a standard
household outlet which provides a pure sine wave. It is recommended that these devices be operated from a standard
household outlet only. This problem does not occur with most battery operated equipment. Most of these devices use a separate
charger or transformer that is plugged into a separate AC socket.
4.6. Placement of Inverter.
4.6.1. For best and safest operation the inverter should be placed on a flat and stable surface, electrically insulated from the vehicle. If required,
fix to an insulated surface by means of the four screws provided.
4.6.2. Use only in a dry location, do not allow inverter to get wet.
4.6.3. Use in cool ambient temperature of between 5°C and 35°C. Do not place on or near a heating vent.
4.6.4. Allow sufficient space around the inverter for cooling. If the inverter overheats it will shut down and will not restart until it has cooled down.
4.6.5. DO NOT use near flammable materials or anywhere that flammable gasses could accumulate.
4.6.6. The inverter may become uncomfortably hot during extended periods of full power use.
WARNING!DO NOT place on or near materials that may be affected by heat.
4.7. Wattage Loading.
4.7.1. Inductive loads, such as TV’s and stereos, require more current to operate than do resistive loads of the same wattage rating. Induction
motors, as well as some televisions, may require 2 to 6 times their wattage rating to start up. The most demanding in this category are
those that start under load, such as compressors and pumps. Testing is the only definitive way to determine whether a specific load can
be started and how long it can run. The unit will simply shut down if it is overloaded. To restart the unit after a shutdown due to
overloading, remove the overload.
NOTE! The inverter will not operate high wattage appliances or equipment that produce heat, such as hair dryers, microwave
ovens and toasters.
4.8. Battery Operating Time.
4.8.1 With a typical vehicle battery, a minimum operating time of 1 to 2 hours can be expected depending on the load draw. It is recommended
that the operator starts the engine every hour to recharge the battery. This will prevent any unexpected shutdown of the equipment and
will ensure that there is always sufficient battery capacity to start the vehicle. The inverter may be used either with the engine running or
turned off. However, the inverter must be switched OFF when starting the vehicle.
4.8.2 The inverter draws less than 1.3 Amperes from the battery when it is not supplying power to a load. In most cases, the inverter may be
left connected to the battery when it is not in use. If the vehicle will not be used for several days, disconnect the unit from the battery.
4.9. The inverter monitors the following potentially hazardous conditions:
4.9.1. Low Battery Voltage - This condition is not harmful to the inverter but could damage the power source. An alarm will sound when input
voltage drops to between 10.2 and 10.8V. The inverter automatically shuts down when input voltage drops to between 9.2 and 9.8V.
When the condition is corrected, the unit may be restarted.
5.1.2 Short Circuit - Reverse polarity or short circuit of the load will usually result in the opening of the short circuit protection and blowing the
fuse(s).
5.1.3 High Temperature - When the temperature of the internal heat sink reaches 65°C, the solid state temperature sensor will automatically
shut down the unit. Once it is allowed to cool, the unit may be restarted.
