IMPORTANT SAFETY INFORMATION

(SAVE THESE INSTRUCTIONS)
This manual contains important safety instructions. Please read and follow all instructions carefully
during installation and operation of the unit. Read this manual thoroughly before attempting to unpack,
install, or operate the unit
Insure the wall outlet and inverter are located near the equipment being attached for proper accessibility.
To reduce risk of damage and injury, please use batteries with good quality.
Provide adequate ventilation for the battery compartment. The battery enclosure should be designed to
prevent accumulation and concentration of hydrogen gas at the top of the compartment.
DO NOT expose the unit to rain, snow or liquids of any type. The unit is designed for indoor use only.
DO NOT obstruct the ventilation openings.
DO NOT connect neutral of the power distribution box on the wall to the output neutral of Inverter.
Otherwise the reversed polarity will damage the Inverter and the connected equipment.
CAUTION! Risk of electric shock, do not remove cover. No user serviceable parts inside.
The battery can energize hazardous live parts inside even when the AC input power is disconnected.
To avoid electrical shock, turn off the Inverter and unplug it from the AC power source before servicing
the battery. Servicing the battery can only be performed by trained personnel.

INSTALLING YOUR Inverter SYSTEM

UNPACKING

Inspect the unit upon receipt. The box should contain the following:
Inverter1; User Manual1; Power cord1

HOW TO DETERMINE THE POWER REQUIREMENTS OF YOUR EQUIPMENT

1. Insure that the equipment plugged into the AC outlet does not exceed the Inverter unit's rated
capacity (refer to TECHNICAL SPECIFICATIONS ). If rated unit capacities are exceeded, an
overload condition may occur and cause the Inverter unit to shut down or the circuit fuse burn down.
2. If the power requirements of your equipment are listed in units other than Volt-Amps (VA), convert
Watts (W) or Amps (A) into VA by doing the calculations below. Note: The below equation only
calculates the maximum amount of VA that the equipment can use, not what is typically used by the
equipment at any one time. Users should expect usage requirements to be approximately 60% of
below value.

HARDWARE INSTALLATION GUIDE

Before installation, please read and understand the following instructions:
1. Placement
The Inverter must be installed in a protected environment away from heat- emitting appliances
such as a radiator or heat register. Do not install this product where excessive moisture is present.
2. Ventilation
The location should provide adequate air flow around the Inverter with 10 CM minimum clearance
on all sides for proper ventilation.
3. Connect the Battery
Connect the external battery pack with the DC cables from the back of the Inverter. Follow battery
polarity guide located near battery cables as below.
"+" Red cable for battery positive polarity;
"-" Black cable for battery negative polarity.
4. Connect to AC and Charge the Battery
Connect the Inverter to a wall outlet. Avoid using extension cords and adapter plugs. Charging the
battery for at least 8 hours is recommended to insure that the battery is fully charged. To recharge
the battery, simply leave the unit plugged into a wall outlet. To maintain optimal battery charge,
leave the Inverter plugged into an AC outlet at all times.
This Inverter can be charged even when Inverter is not turned on.
5. Connect the Load
Connect the equipment to the Inverter outlet. Please make sure that the total loads of your
equipments are less than the maximum total power load of the Inverter.
BASIC OPERATION
DESCRIPTION
1. Power Switch
Press the power switch to turn the Inverter ON or OFF.
2. AC Mode LED
The green LED will light when utility power is normal.
3. Battery Mode LED
The yellow LED will light when power mains are abnormal and the unit will work in battery mode.
4. Fault LED
The red LED will light when fault or over load occurs.
5. AC outlet**
The unit provides one outlet for connected equipment to insure temporary uninterrupted operation
during a power failure and against surges and spikes.
**Note: 2 outlet types available, including Schuko and FR, type.
6. AC Inlet
Connect to utility power through the input power cord.
7. Input Voltage Range Selector
Input voltage range is defined in specification section. Output voltage is the same as input voltage
in AC mode.
A. Select "Narrow" setting for general electrical appliance such as TUBE LIGHT, ENERGY
SAVING LAMP, TV, JUICER & MIXER etc. It is not suitable for high-power motor or inductive
load, such as the fridge of 1KW, the motor of 800W, AIR COOLER（having risk of rebooting）
and so on. In this mode, the Inverter operating voltage in AC mode is within 190~260Vac with
the same output voltage. The line sensitivity is higher.
B. Select "Wide" setting to save energy. In this mode the operating range of voltage for the
Inverter is 100-290Vac. Therefore the output voltage will be the same as the MAINS input
voltage. The Inverter unit in this mode has a lower sensitivity with a longer transfer time for
switching from AC mode to battery mode in the event of power failure. You can safely connect
and use home appliances which are not sensitive to transfer time limitations such as florescent
tubes, bulbs, TV etc.
8. DC Input Cable (Red)
Connect to battery positive polarity.
9. DC Input Cable (Black)
Connect to battery negative polarity.

Functional Test

AC Mode
The Inverter delivers power to the load derived from the utility and maintains proper battery charge.
On-Battery Mode
The Inverter operates on battery when the utility voltage has fallen outside the limits. Local users are
alerted to this mode of operation by visual and audible indicators. The Inverter provides power to the
load from the battery and the output voltage of the Inverter are regulated within a narrow range
1. Switch On
Press the power switch then the status LED will light up.
2. Switch Off
Press again the power switch, the status LED will go off.
3. Cold Start / Start on Battery:
This Inverter can be turned on even when AC is not present.
Press the power switch then the status LED will light up.

ROUTINE MAINTENANCE AND STORAGE

ROUTINE MAINTENANCE

1. Use dry soft clothes to clean the panel and plastic parts. Do not use any detergent that contains
alcoholic ingredient.
