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.
9.2 5V DC USB OUTPUT – FIG. 7
− Insert USB plug

. 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.
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.
