2. CONNECTIONS
Connect to lighter for appliances 0-150W or connect directly to battery (clips

included) for appliances of 150-300W . The length of the cable is ≤ 2m.
Please verify if you have chosen the right operating voltage for both input and output.

3. OPERATION
When connected to an appliance, remember to turn on the inverter before turning

on the appliance. If the buzzer sounds during operation, this indicates that the
battery voltage is very low and that the inverter will be disconnected in 5 minutes.

4. OUTPUT CAPACITY
The inverter will switch off automatically if the total wattage of the electrical

appliances exceeds the inverter's output capacity. This will also happen if the
temperature of the inverter exceeds 55°C due to prolonged use.

5. SPECIAL RECOMMENDATIONS
Unplug the AC inverter when not in use and when starting the vehicle's motor.
If the AC inverter makes a beeping sound : switch off your appliance, unplug the

inverter and restart your vehicle's engine. The beeping sound is simply the low­battery warning which indicates that the voltage of your battery is getting low.
Your inverter will shut down automatically if you do not restart your engine and
continue the use of your inverter. This will leave your vehicle's battery at about

10.5VDC (21VDC for a 24V inverter), enabling you to start your engine and
resume operation of the inverter. It also eliminates the possi bil ity of being
stranded with a dead battery.

To avoid over-discharging the battery, it is advisable to let your engine run for 10
to 20 minutes after every 2-3 hours of using the AC inverter. This allows your
vehicle's battery to recharge.

Please remember to connect the "+" wire to the "+" terminal and the "-" wire to the
"-" terminal if you choose to use an adapter for a direct connecti on between the
AC inverter and the battery terminals. IF YOU CONNECT THE WIRES TO
INCORRECT TERMINALS, THE POLARITY WILL BE REVERSED AND THIS
WILL DAMAGE THE INVE RTER. REVERSED POLARITY WILL INSTANTLY
VOID YOUR INVERTER'S WARRANTY.

Please remember to disconnect the AC inverter before using the battery charger
to replenish you battery's voltage. Failure to disconnect the inverter prior to
connecting a charger may result in an input spike which will damage the inverter.
CONNECTING THE INVERTER'S INPUT TO A BATTERY CHARGER WILL
VOID THE WARRANTY AND MAY DAMAGE THE INV ERTER.

The battery's voltage must never exceed 15VDC (30VDC for a 24V inverter).
CONNECTING THE INVERTER TO A DC POW ER SOURCE GREATER THAN
15VDC (30VDC) WILL VOID THE WARRANTY AND MAY DAMAGE THE
INVERTER.

6. ADDING EXTENSION CO RDS
We recommend that the buyer refrain from using an extension cord between the

DC power source and the inverter's DC input. Connecting an extension cord to
the DC input will create a voltage drop, entailing reduced efficiency and output.
Instead, we recommend the use of an extension cord between the AC output and
the AC appliance. You may use up to 100ft (30m) of high quality extension cord.
A longer cord may result in reduced power.

7. EARTHING CONNECTION

WARNING : YOU MUST PROVIDE THE INVE RTER WITH AN EARTHING
CONNECTION BEFORE USING THE INVERTER.

• The rear panel of the inverter is equipped with a terminal fitted with a wing nut.
This terminal is connected to the case of the inverter and also to the ea rthi ng
terminal of the AC output socket. The nature of your installation will determine
whether or not you need this terminal. Always use heavy-duty yellow and green
wiring for this connection.

• In a stationary land-based installation, the earthing terminal should be
connected to a metal earthing stake driven into the ground to a minimum depth
of 1.2m. One of the battery terminals (preferably the negative one) should also
be connected to the earthing stake if the battery system powering the inverter is
not equipped with a ground connection.

• If the inverter is used in a vehicle, where it is wired directly to the battery, the
earthing terminal is simply connected to the chassis of that vehicle. If, however,
the inverter has to power equipment used outside the vehicle, an earthing stake
should be used as described above.

• Connect the earthing terminal to the existing grounding system when the
inverter is used on a boat.

NOTE : The earthing terminal of the AC outlet is connected to the neutral

terminal. This is the same as with a standard household po wer point
where the neutral connection is bonded to earth and there is no voltage
between the two.

8. FUSE

Please check the fuse if the voltage indicator is not lit during operation. Replace
blown fuses with an identical one.

FUSE : max. 35A for a 12V inverter or 20A for a 24V inverter.

9. MEASURING AC VOLTAGES

The output wave of the AC inverter is a MODIFIED SINEWAVE. If you choose to
measure the AC output voltage, you must use an AUTHENTIC RMS VOLT
METER. Using any other type of voltage measuring device will result in an AC
voltage reading that is up to 20 to 30 volts lower than the rated value. The reading
will only be accurate when using an authentic RMS voltmeter.

10. VENTILATION

IMPORTANT ! During operation, make sure the fan keeps revolving. Check the
inverter for possible malfunctions if the fan does not work when this unit is being
used.

Make sure the fan is not blocked in order to avoid poor ventilation.

11. CHASSIS EARTHING

The chassis earthing lug should be connected to an earthing point. This point will
vary depending on where the power inverter is installed. If the power inverter is
installed in a vehicle, you should connect the chassis ground lug to the chassis of the
vehicle. If the inverter is being used on a boat, you should connect it to the boat's
grounding systems. Connect your inverter to earth if used in a fixed location.

12. CAUTION

In case of trouble with the AC output, e.g. short-circuit, overload, etc… the
protection circuit will automatically cut off the output.
In such cases : (A) switch off the power at once
(B) disconnect all units
(C) check the connected devices
(D) use the units again as soon as any problems

concerning the connected devices have been solved

When in use for a prolonged period of time, the AC output may suddenly be cut
off although the battery voltage is still very strong. This may be caused by
excessive temperatures. If this happens, please proceed as follows :
(A) Switch off the inverter at once
(B) Disconnect some of the appl iances or wait until the inverter cools off
(C) S witch the inverter back on

Always keep the inverter in an environment which is :
(A) Well-ventilated
(B) Not exposed to direct sunlight or any other heat source
(C) Inaccessible to children
(D) Safe from water/moisture, oil or grease
(E) Safe from any flammable substance

If the inverter is connected in the wrong way, this will void the warranty.

13. MAINTENANCE

Very little maintenance is required to keep your inverter operating smoothly.
Clean the exterior of the device periodically using a damp cloth in order to prevent
the accumulation of dust and dirt. Tighten the screws on the DC input terminals
whenever you are cleaning the device.
