(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 UPS.
Insure the wall outlet and UPS 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 UPS to rain, snow or liquids of any type. The UPS 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
UPS. Otherwise the reversed polarity will damage the UPS 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 UPS and unplug it from the AC power source before
servicing the battery. Servicing the battery can only be performed by trained personnel.

Inspect the UPS upon receipt. The box should contain the following:
(1) UPS Unit 1; (2) User Manual 1
OVERVIEW
The UPS provides battery backup during power outages. The SmartDual series ensures
consistent power to your computer system and its included software will automatically save
your open files and shut down your computer system during a utility power loss.
The 1500/2000 model can connect external batteries for longer back up time.
HARDWARE INSTALLATION GUIDE
Before installation, please read and understand the following instructions:
1. Placement
The UPS 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 UPS with 10 CM minimum
clearance on all sides for proper ventilation.
3. Connect the Battery(only for 1500/2000VA)
Connect the external battery with the DC cables from the back of the UPS. Follow
battery polarity guide located near battery cables as below.
Red wire for battery positive polarity;
Black wire for battery negative polarity.
4. Connect to AC and Charge the Battery
Connect the UPS 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 UPS plugged into an AC outlet at all
times.
This UPS can be charged even when UPS is not turned on.
5. Connect the Load
Connect the equipment to the UPS outlet. Please make sure that the total loads of your
equipment are less than the maximum total power load of the UPS. Connect your
