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.

3-1-10. AC Outlet (Outlet sockets available):

North America (GFCI) North America (NEMA 5-15R)

Continental European (SCHUKO)Australia / New Zealand

United Kingdom

Universal

3-2. Rear Panel Operations

3-2-1. Ventilation Openings

Do not obstruct, allow at least 3 inch for air flow.

3-2-2. DC Terminals

Connect to 12V / 24 V battery or the other power sources.

【+】is positive, 【-】is negative. Reverse polarity connection will

blow internal fuse and may damage inverter permanently.

Model voltage Min voltage Max. voltage

SA-1500-112 10.0 VDC 16.0 VDC

SA-1500-124 20.0 VDC 32.0 VDC

WARNING!

Do not connect the 12V model to a 24 battery,

The unit will be destroyed immediately.
