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.

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.
Either mode is front panel programmable.
In the first option, Off-line mode,
A
C output power will be supplied through
the AC bypass mode in its normal operation. Upon AC input failure, output
power will be diverted through the DC to AC Inverter Mode. Once AC
mains are restored, the unit will revert from the Inverter Mode to the
Bypass Mode.
In the second option, On-line mode, AC output power will be provided
directly by the inverter from the DC source. Should the DC source or
inverter fail, the system will transfer its output power through the bypass
mode. Once the DC power source is restored, the system will revert to the
inverter mode.
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.
WARNING!
The above two option are fixed during the production and
customer unable to modify.

3-1-1. Power ON / OFF / REMOTE (Main) switch:
a. Before installing the inverter, you need to ensure the main switch
is in the OFF position.
b. Before using the remote unit, you need to ensure the main switch
is in the REMOTE position.
3-1-2. AC input Circuit Breaker:
The AC input circuit breaker protects the model from overload.
When an overload condition exists, the circuit breaker stops to supply
output AC grid power. To reset it, push the circuit breaker switch
then the model will be back in normal operation. The source fault
should be corrected before you reset it.

3-3 DC Wiring Connections
Follow the instructions to connect the battery cables to DC input terminals of
the Inverter. The cable should be as short as possible (less than 6 feet / 1.8
meters ideally) so that it can handle the required current in accordance with
the electrical codes or regulations application. Inappropriate length of cables
will deteriorate the inverter performance such as poor surge capability,
frequent low-input voltage warnings, and shutdown. UVP warning occurs
when DC voltage drops across the cables from the inverter to the batteries.
The longer or narrower the cables, the more the voltage drop.
Increasing your DC cable size will help improve the situation.
The following recommended cables are for the best performance of the
inverter. (Apply both 120V and 230V versions)

3-3-1. Connect the cables to the power input terminals on the front panel of the
inverter. The red terminal is positive (+) and black terminal is negative (-).
Insert the cables into the terminals and tighten screw to clamp the wires
securely.
Also, only use high quality copper wire and keep the cable length short
which is a maximum of 3 - 6 feet.
Do not place anything between
battery cable lug and terminal surface.
Assemble exactly as shown.
AWG#2 - #6
Battery to inverter cable connection
WARNING!
The installation of a fuse must be on positive cable.
Failure to place a fuse on “+” cables running between
the inverter and battery may cause damage to the
inverter and will void warranty.
WARNING!
Make sure all the DC connections are tight (torque
to 9 – 10 ft-lbs, 11.7 – 13 Nm). Loose connections
could result overheat in a potential hazard.
