User Manual
1. Introduction
The Vu Phong Sine Wave series models are used in a wide range
of applications. It will operate most televisions, fans, lamps,
personal computers, small appliances and tools.
The inverter must have a greater power rating than the
load it provides power to.
To get the most out of the power inverter, it must be installed
and used properly.
Please read the instructions in this manual before installing and
using this model.

3. Name and Main Function
3.1. Back side
a) ON / OFF switch: Power ON/OFF switch, leave in the OFF
position during installation.
b) Ventilation port(s): Allow air flow. Do not obstruct.
c) Battery Cables w/ Cable shoe: Connect to 12V battery.
Red is positive; Black / Blue is negative.
3.2. Front side
a) AC outlets: Connect to 220V loads
b) Green Power switch (S400VA / S1500VA): Energy saving
enable. Turn the switch ON to reduce the consumption
of the battery when AC output is without load.
c) LED indicators:
S400VA
-Fault: over temperature / over load (red)
-Normal (green): normal operation (green)
S1000VA
-Fault: over temperature; over load (red)
-Normal: normal operation (green)

4. Installation
4.1. Where to install
The power inverter should be installed in a location that meets
the following requirements:
a) Dry - Do not allow water to drip or splash on the inverter.
b) Cool - Ambient air temperature should be between 0°C and
40°C (the cooler the better).
c) Ventilated - Allow at least two inches of clearance around the
inverter for air flow. Ensure the ventilation openings on the rear
and side of the unit are not obstructed.

d) Safe - Do not install the inverter in the same compartment as
batteries or in any compartment capable of igniting flammable
liquids such as gasoline.
e) Keep the product away from children
4.2. Hook-up and testing
a) Unpack and inspect your Vu Phong Inverter, check to see that
the power switch is in the OFF position.
b) Connect the Red cable of the inverter to the positive (+)
terminal of the battery and the Black / Blue cable to the
negative (-) terminal of the battery. Tighten the screw to
clamp the wires securely.
Caution! Loose connections result in excessive voltage drop and
may cause overheated wires and melted insulation.
Caution! A reverse polarity connection may blow a fuse in the
inverter. Damage caused by reverse polarity connection is not
covered by our warranty.
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, as explosion or fire may result.
c) Plug the test load into the AC receptacle on the front panel of
the inverter. Leave the test load switch OFF.
