1. Important Safety Information

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 take place.

1-1-2

To avoid a risk of fire and electric shock, please 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, 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 wash eyes 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 or 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 similar item to metal causing a severe burn.

WARNING!

Before using the Inverter, read and save the safety

instructions.

1-3. Installation

The power inverter should be installed in a location that meets the following

requirements:

1-3-1

Dry –Do not allow water to drip or splash on the inverter.

1-3-2

Cool –Ambient air temperature should be between -20℃and 50℃,

but he cooler the better.

1-3-3

Safety –Do not install batteries in the compartment or other areas

here flammable fumes existence such as fuel storage areas or

engine compartments.

1-3-4

Ventilated –Allow at least one inch of clearance around the Inverter

for air flow. Ensure the ventilation shafts on the rear and bottom of

the unit are not obstructed.

1-3-5

Dust-free –Do not install the Inverter in dusty environments here

dust, wood particles or other filings/shavings are present. The dust

can be pulled into the unit when the cooling fan is in operation.

1-3-6

Close to batteries –Avoid excessive cable lengths but do not install

the inverter in the same compartment as batteries.

Use the recommended wire lengths and sizes (see section 4-3).

Do not mount the inverter where it is exposed to the gases

produced by the battery. These gases are very corrosive and

prolonged exposure will damage the inverter.

2. Functional Characteristics

2-1. General Information

SD-series is new generation power inverter equipped with N+1 parallel power

function , 3-phase capability, and AC transfer switch. SD series is suitable for RV,

Marine and Emergency appliances.

WARNING !

Shock Hazard. Before proceeding further, carefully check that the

inverter is NOT connected to any batteries, and that all wiring is

disconnected from any electrical sources . Do not connect the

output terminals of the inverter to an incoming AC source.

Features

Parallel redundancy design for power expansion

Multiple industrial applications that create 1Ф3ω / 3Ф4ω power systems

User-friendly remote control

Automatic master mechanism to eliminate single point failure and optimize

reliability

Built-in ATS and AC circuit breaker

Optional STS module, transfer time is less than 4ms.

RS-232 communication

Input & output fully isolation

Output voltage / power saving mode is selectable by DIP switch and remote

control (CR-10)

Input Protection: Reverse Polarity (Fuse) / Under Voltage / Over Voltage

Protection

Output Protection: Short Circuit / Overload / Over Temperature / Over Voltage

Protection

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 of this

model.
