1. Important Safety Instructions

WARNING !

Before using the Inverter, read and save the 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.

2. Functional Characteristics

2-1. General Information

ST-series completes with stand –alone power inverter with AC transfer

switch and is suitable for RV, Marin and Emergency appliances.

When utility AC power cutoff, the transfer relay is de-energized and the

load is automatically transferred to the Inverter output. Once the AC utility

is restored, the relay is energized and the load is automatically

reconnected to AC utility.

This power inverter series is a 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 installation and

operation this model.

2-2. Application

2-2-1 Power tools–circular saws, drills, grinders, sanders, buffers, weed and

hedge trimmers, air compressors.

2-2-2. Office equipment – computers, printers, monitors, facsimile machines,

scanners.

2-2-3. Household items – vacuum cleaners, fans, fluorescent and incandescent

lights, shavers, sewing machines.

2-2-4. Kitchen appliances – coffee makers, blenders, ice markers, toasters.

2-2-5 Industrial equipment – metal halide lamp, high – pressure sodium lamp.

2-2-6. Home entertainment electronics – television, VCRs, video games,

stereos, musical instruments, satellite equipment.

2-3. Features

2-3-1. Pure sine wave output (THD < 3%) to operate higher-end electronic

Equipments.

2-3-2. Output frequency：50 / 60Hz switch selectable

2-3-3. Built in 16A or 25A rating transfer switch.

2-3-4. Speed up transfer time and synchronized operation with the AC source

at all times that allows the transfer to be interruption-free for sensitive

equipments.

2-3-5. Built in advance microprocessor to make friendly interface with user.

2-3-6. Low power “ Power Saving Mode “ to conserve energy

2-3-7. Capable of driving highly reactive & capacitive loads at start moment.

2-3-8. Hardwire AC connection model option.

2-3-9. Loading controlled cooling fan.

2-3-10. Smart remote controller.

2-3-11. 3 LED indicators with tri-color display all operation status.

2-3-12. High efficiency 88 ~ 93%.

2-3-13. Protection:

Input over voltage and Input low voltage protection.

Low battery alarm

Over temperature protection.

Over load protection

Short Circuit protection

Reverse polarity protection.
