safety instructions.
A. General Safety Precautions
A-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.
A-2. To avoids 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.
B. Explosive Gas Precautions
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.
C. Precautions When Working With Batteries
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.

G. Connection And Testing:
For a quick connection and performance check,
please follow these guidelines.
G-1. Unpack and inspect the power inverter, check to see
that the power switch in the OFF position.
G-2. Connect the DC NEGATIVE cable to the Negative
(NEG-) terminal on the battery. Next, connect the
BLACK cable to the negative terminal on the inverter.
The connection to the negative terminal of the
inverter should be the last connection made. A spark
when making this final connection is normal.
G-3. Before proceeding further, carefully check that cable
you have just connected from the negative terminal of
inverter to the Negative output terminal of power
source.
G-4. Connect the RED cable from the positive terminal of
inverter to the positive terminal of the power source.
Make secure connection.
WARNING!
Make sure tall the DC connections are tight (torque
to 9-10 ft-lbs, 11.7-13 Nm). Loose connections
will overheat and could result in potential hazard.
WARNING!
Reverse polarity connection will blow a fuse in
Inverter and may permanently damage the inverter.
Damage caused by reverse polarity connection is
not covered by our warranty.

G-5. Set the power switch to the ON position, the indicator
lights may blink and the internal alarm may sound
momentarily. This is normal.
G-6. Check the meters and indicators on the front panel of
the inverter. The voltage bar graph indicate
depending on the voltage of the power source.
If it does not, check your power source and the
connections to the inverter. The other indicators
should be off. Plug the test load into the AC
receptacle on the front panel of the inverter. Leave
the test load switch off.
G-7. Set power inverter switch to the ON position and turn
the test load on, the inverter should supply power to
the load. If you plan to measure the true output r.m.s.
Voltage of inverter, the meter such as FLUKE 45
BACKMAN 4410 or TRIPLETT 4200 or other digital
meters must be used.
H. Installation:
H-1. Where to install
The power inverter should be installed in location that
meets the following requirements:
H-1-1. Dry
Do not allow water to drip or splash on the inverter.
WARNING!
Reverse polarity connection will blow a fuse in
Inverter and may permanently damage the inverter.
Damage caused by reverse polarity connection is
not covered by our warranty.

H-1-2. Cold
Ambient air temperature should be between 0℃
and 40℃, the cooler the better.
H-1-3. Safe
Do not install in battery compartment or other areas
where flammable fumes may exist, such as fuel
storage are as or engine compartments.
H-1-4. Ventilated
Allow at least one inch of clearance around the
inverter for air flow. Ensure the ventilation openings
on the rear and bottom of the unit are not
obstructed.
H-1-5. Dust-free
Do not install the Inverter in a dusty environment where
either dust, wood particles or other filings/ shavings
are present. These can pulled into the unit when the
cooling fan is operating.
H-1-6. Close to battery/ batteries
Avoid excessive cable lengths but do not install the
Inverter in the same compartment as batteries. Also
do not mount the Inverter where it will be exposed to
the gases produced by the battery. These gases are
very corrosive and prolonged exposure will damage
the Inverter.
H-2. AC safety Grounding:
During the AC wiring installation, AC input and output
ground wires are connected to the inverter. The AC input
ground wire must connect to the incoming ground from
yourAC utility source.
The AC output ground wire should go to the grounding
point for your loads (for example, a distribution panel
ground bus.)

- -
9
H-2-1. Neutral Grounding:
H-2-1-1. 120V model：
The neutral conductor of the AC output circuit of the
Inverter is automatically connected to the safety
ground during inverter operation. This conforms to
National Electrical Code requirements that separately
derived AC sources (such as inverter and generators)
have their neutral conductors tied to ground in the
same way that the neutral conductor from the utility is
tied to ground at AC breaker panel. For models
configured with a transfer relay, when AC utility power
is present and the Inverter is in bypass mode, this
connection (neutral of the Inverter’s AC output to input
safety ground) is not present so that the utility neutral
is only connected to ground at your breaker panel, as
required.
H-2-1-2. 230V models:
There is no connection made inside the Inverter from
either of the line conductors (line or neutral) to the
safety ground.
Ground Fault Circuit Interrupters (GFCI'S)
Installations in Recreational Vehicles (for North American
approvals) will require GFCI protection of all branch circuit
connected to the AC output of the hardwire terminal equipped
Inverter. In addition, electrical codes require GFCI protection of
WARNING!
Do not operate the power inverter without
connecting it to ground.
Electrical shock hazard may result.

10
certain receptacles in residential installations. While the true
sine wave output of the Inverter is equivalent to the waveform
provided by utilities, compliance with UL standards requires us
to test and recommend specific GFCI’s. State power has tested
the following GFCI-protected 15A receptacles and found that
they functioned properly when connected to the output of the
Inverter.
H-3. Making DC Wiring Connections:
Follow this procedure to connect the battery cables to
the DC input terminals on the Inverter. Your cables
should be as short as possible (ideally, less than 10
feet/ 3 meters) and large enough to handle the
required current, in accordance with the electrical
codes or regulations applicable to your installation.
Cables that are not an adequate gauge (too narrow) or
are too long will cause decreased inverter
performance such as poor surge capability and
frequent low input voltage warnings and shutdowns.
These low input voltage warning is due to DC voltage
drop across the cables from the inverter to the
batteries. The longer and narrower these cables, the
greater the voltage drop.
I. Operation:
To operate the power inverter, turn it on using the ON/ OFF
switch on the front panel. The power inverter is now ready to
deliver AC power to your loads. If you are operating several
loads from the power inverter, turn them on separately after
the inverter has been turned on. This will ensure that the
power inverter does not have to deliver the starting currents
for all the loads at once.

- -
11
I-1. Controls and indicators:
The ON/ OFF switch turns the control circuit in the power
inverter on and off. It does not disconnect power from the
power inverter. The inverter operates from an input
voltage ranging from:
10 to 16 VDC for 12V models.
20 to 32 VDC for 24V models.
42 to 62 VDC for 48V models.
Peak performance for these inverter occurs when DC
input voltage is in the Range of 10 volts to 16 volts for
12V models and 20 volts to 32 volts for 24V models, and
42 volts to 62 volts for 48V models. From 600Watts up to
3000Watts.
l-2. 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 areas of the bar graph. If the voltage goes into the
red area at top and bottom of the graph, inverter may shut
down.
I-3. Load watt indicator:
The AC load watt bar graph indicates the power drawn
from the power inverter. It will indicate watt by loads. For
long term operation, the watt should in the green &
orange area of the bar graph. Short-term operation is
possible with watt in the red area. If the watt rises to the
flash all bar, the inverter will protect it-self.

- -
12
I-4. Over voltage indicator:
The over voltage indicator indicates that the power
inverter has shut itself down because its input voltage has
exceeded over detected voltage 12/ 24V version.
I-5. Under voltage indicator:
The under voltage indicator indicates that the power
inverter has shut itself down because its input voltage has
been lower than detect voltage 12/ 24V version.
I-6. Over temp indicator:
The over temp indicator indicates that the power inverter
has shout itself down because it 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.
I-7. Overload indicator:
The overload indicator indicates that the power inverter
has shut itself down because its output circuit 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.
J. Operating Limits:
J-1. Power output:
The inverter will operate most AC loads within its power
rating. When deeming whether a microwave oven can be
operated by the inverter, remember that the power
commonly advertised for microwave ovens is the cooking
power (the power delivered to the food) not the power
actually consumed by the microwave oven. The

- -
13
microwave over will consume 40% to 100% more than its
advertised cooking power. Check the rating sticker on the
back of the over to determine its actual power draw.
The Power inverter may not be able to start some motors
even though their rated current draw is within the power
inverter. If motor refuse to start, observe the battery
voltage indicator while trying to start the motor. If the
battery voltage indicator drops below 11 volts while
inverter is attempting to start the motor, this may be why
the motor won’t start. Make sure that the battery
connections are good and that the battery is fully charged.
If the connections are good and the battery is charged,
but the voltage still drops below 11 volts, you may need to
use a larger battery.
K. Trouble shooting:
K-1. Common problems Television interference:
Operation of the power inverter can interfere with
television reception on some channels. If this situation
occurs, the following steps may help to alleviate the
problem.
◆Make sure that the chassis ground lug on the back
of the power inverter is solidly connected to the
ground system of your vehicle, boat or home.
◆Do not operate high power loads with the power
inverter while watching television.
◆Make sure that the antenna feeding your television
provides an adequate (“Snow free”) signal and that
you are using. Good quality cable between the
antenna and the television.
◆Move the television as far away from the power

14
inverter as possible.
◆Keep the cables between the battery and the
power inverter as short as possible and twist them
together with about 2 to 3 twists per foot.
This minimizes radiated interference from the cables.
