is disconnected from any electrical sources. Do not connect
the output terminals of the inverter to an incoming AC source.

8
2-3 Installation:
Where to install;
The power inverter should be installed in a location that meets the following requirements.
2-3-1 Dry – Do not allow water to drip or splash on the inverter.
2-3-2 Cool – Ambient air temperature should be between -20and 50, the cooler the
better.
2-3-3 Safe – Do not install in a battery compartment or other areas where flammable
fumes may exist, such as fuel storage areas or engine compartments.
2-3-4 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.
2-3-5 Dust-free – Do not install the Inverter in a dusty environments where are dust, wood
particles or other filings/shavings. The dust can be pulled into the unit when the
cooling fan is operating.
2-3-6 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 ( Ref. point 2-6).
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.
2-4 Quick hooks – up and testing:
2-4-1 Unpack and inspect the power inverter, check to see that the power switch in the OFF
position.
2-4-2 Connect the cables to the power input terminals on the rear panel of power inverter.
The red terminal is positive (+) and black terminal is negative (-).
Insert the cables into the terminals and tighten relative nut to clamp the wires securely.
WARNING!
You may observe a spark when you make this connection since
current may flow to charge capacitors in the power inverter.
Do not make this connection in the presence of flammable fumes.
Explosion or fire may result.

9
2-4-3 Before proceeding further, carefully check that cable you have just connected
negative terminal of inverter to the negative output power source.
2-4-4 Connect the cable from the positive terminal of the inverter to the positive
terminal of the power source. Make a secure connection.
WARNING!
You may observe a spark when you make this connection since
current may flow to charge capacitors in the power inverter.
Do not make this connection in the presence of flammable fumes.
Explosion or fire may result.
2-4-5 Set the power switch to the ON position; you will hear the “bi-bi-bi” sound. At the
same time, the display is showed the word “ASIAN” for two times. After that,
you will hear the continuous sound from internal alarm. Then, the AC voltage
shows on the display. It means the device has done the operation.
2-4-6 Set the power switch to the OFF position; the device shut down completely.
2-4-7 Please use a power meter accurately measure the true output R.M.S. voltage of
inverter. We use a power meter such as IDRC CP-350 or ABM 2019 to measure
our product.
2-5 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 your AC utility
source.
The AC output ground wire should go to the grounding point for your loads (for example, a
distribution panel of ground bus).
WARNING!
Make sure all the DC connections are tight (torque to 9-10 ft-lbs,
11.7-13Nm). Loose connections will overheat and could result in
a potential hazard.
CAUTION!
Reverse polarity connection will blow a fuse in inverter and may
permanently damage the inverter.
Damage caused by reversing polarity connection is not covered by
our warranty.

10
2-5-1 Neutral Grounding (GFCI’s):
2-5-1-1 120V models: The neutral conductor of the AC output circuit of the Inverter is
automatically connected to the safety ground during inverter operation. According
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 the GFCI
breaker panel. For models configured with a transfer relay, while AC utility power
is presenting 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.
2-5-1-2 230V models: There is no connection made inside the Inverter from either the
line or neutral conductor 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 certain receptacles in
residential installations. While the pure 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. Our company has tested the following GFCI-protected 20A
receptacles and found that they functioned properly when connected to the output of the
inverter.
2-6. Marking 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 warnings are 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.
WARNING!
Do not operate the power inverter without connecting it to Ground.
Electrical shock hazard may result.

11
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.
Increasing your DC cable size will help improve the situation.
Our company recommends the following cables for optimum inverter performance (apply
both 120V and 230V versions)

Also, use only high quality copper wiring and keep cable length short from 3-6 feet.
2-7 Inverter 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.
2-7-1 Controls and indicators:
The ON / OFF switch turns the control circuit in the power inverter on and off.
The PSW2KVA/E Inverter operates from an input voltage ranging from:
10.0 to 16.0 VDC for 12V models
20.0 to 32.0 VDC for 24V models
42.0 to 62.0 VDC for 48V models
90.0 to 140.0VDC for 110V models
180.0 to 275.0VDC for 220V models
The Inverter will indicate high and low DC voltage conditions as follows:

2-7-8 Over voltage protection indicator: (OVP)
The over voltage indicator indicates that the power inverter has shut itself down because
its input voltage exceeded 12V/24V/48VDC version. ( Ref. point 2-7-1 )
2-7-9 Under voltage protection indicator: (UVP)
The under voltage indicator indicates that the power inverter has shut itself down because
its input voltage fell below 12V/24V/48VDC. ( Ref. point 2-7-1 )
2-7-10 Over temp protection indicator: (OTP)
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 automatically
back up, once it has cooled off.
2-7-11 Overload protection indicator: (OLP)
The overload indicator indicates that the power inverter has shut itself down. When
output voltage over continue power, then must return to operate manually.
2-8 Cooling fan working code:
Cooling fan of inverter is through detecting output power and over temperature situation to
work.
When start to turn on the inverter and output power is under 300W, the cooling fan does not
start running. It complies with saving energy sources requirement. Until, output power is up
to 300W, the cooling fan will start to work in order to drop the inner temperature.
If the ventilation opening is obstructed, the inverter will enter over temperature protection
mode (OTP). The cooling fan will continue working to drop the inner temperature. When the
temperature comes down to normal situation, the inverter will turn on automatically.
