1. Important Safety Instructions
1-1. General Safety Precautions
1-1-1. Do not expose the Inverter to rain, snow, spray, bilge or dust.
To reduce risk of hazard, do not cover or obstruct the ventilation
openings. Do not install the Inverter in a zero-clearance compartment.
Overheating may result.
1-1-2. To avoid a risk of fire and electronic shock. Make sure that existing
wiring is in good electrical condition; and that wire size is not
undersized.
Do not operate the Inverter with damaged or substandard Wiring.
1-1-3. This equipment contains components which can produce arcs or
sparks. To prevent fire or explosion do not install in compartments
containing batteries or flammable materials or in locations which
require ignition protected equipment. This includes any space
containing gasoline-powered machinery, fuel tanks, or joints, fittings,
or other connection between components of the fuel system.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters eye, immediately flood eye with running
cold water for at least 20 minutes and get medical attention
immediately.
1-2-2. Never smoke or allow a spark or flame in vicinity of battery or Engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or
short-circuit on the battery of other electrical part may cause an
explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces,
and watches when working with a lead-acid battery,
A lead-acid battery produces a short-circuit current high enough to
weld a ring or the like to metal, causing a severe burn.
WARNING!
Before using the Inverter, read and save the safety
instructions.

3. Introduction
This power inverter series is the member of the most advanced line of mobile AC
power systems available.
To get the most out of the power inverter, it must be installed and used properly.
Please read the instructions in this manual before installing and using this model.
3-1. Front Panel Operations
3-1-1. Front view
3-1-2. ON / OFF switch
Power ON/OFF switch, leave in the OFF position during installation.
3-1-3. Battery Voltage indicator
The battery voltage bar graph indicates the voltage at the input
terminals of the power inverter. At low input current, this voltage is very
close to the battery voltage. At high input current, this voltage will be
lower than the battery voltage because of the voltage drop across the
cable and connections. Ideally, the voltage should remain in the green
Ares of the bar graph. If the voltage goes into the red area at top and
bottom of the graph, inverter may shutdown.

3-1-4. Battery Voltage indicator
The AC load watt bar graph indicates the power drawn from the power
inverter by the load. For long term operation, the watt indicator
should remind in the green & orange area of the bar graph.
Short term operation is possible with watt indicator in the red area.
If the watt indicator rises to high values the bar will flash and the
inverter will shutdown to protect itself.
3-1-5. OVP : Over Voltage indicator
The over voltage indicator indicates that the power inverter has shut
itself down because its input voltage exceeded 12 / 24 VDC version.
3-1-6. UVP : Under Voltage Protection indicator
The under voltage indicator indicates that the power inverter has shut
itself down because its input voltage fell below 12 / 24 VDC.
3-1-7. OTP : Over Temperature Protection indicator
The over temp indicator indicates that the power inverter has shut itself
down because its temp has become overheated. The power inverter
may overheat because it has been operated at power levels above its
rating, or because it has been installed in a location which does not
allow it to dissipate heat properly. The power inverter will restart
automatically, once it has cooled off.
3-1-8. OLP : Over Load Protection indicator
The overload indicator indicates that the power inverter has shut itself
down because its output has been short circuited or drastically
overloaded.
Switch the ON/OFF switch to OFF, correct the fault condition, and then
switch the ON/OFF switch back to ON to reset the unit.
3-1-9. Power Saving: Power energy saving enable.
See appendix 9-2 for detailed information.
