1. Important Safety Warning
Please comply with all warnings and operating instructions in this manual strictly. Save this
manual properly and read carefully the following instructions before installing the unit. Do not
operate this unit before reading through all safety information and operating instructions
carefully
1-1. Transportation
Please transport the UPS system only in the original package to protect against shock
and impact.
1-2. Preparation
Condensation may occur if the UPS system is moved directly from cold to warm
environment. The UPS system must be absolutely dry before being installed. Please
allow at least two hours for the UPS system to acclimate the environment.
Do not install the UPS system near water or in moist environments.
Do not install the UPS system where it would be exposed to direct sunlight or near
heater.
Do not block ventilation holes in the UPS housing.
1-3. Installation
Do not connect appliances or devices which would overload the UPS system (e.g.
laser printers) to the UPS output sockets.
Place cables in such a way that no one can step on or trip over them.
Do not connect domestic appliances such as hair dryers to UPS output sockets.
The UPS can be operated by any individuals with no previous experience.
Connect the UPS system only to an earthed shockproof outlet which must be easily
accessible and close to the UPS system.
Please use only VDE-tested, CE-marked mains cable (e.g. the mains cable of your
computer) to connect the UPS system to the building wiring outlet (shockproof
outlet).
Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS
system.
When installing the equipment, it should ensure that the sum of the leakage current
of the UPS and the connected devices does not exceed 3.5mA.
1-4. Operation
Do not disconnect the mains cable on the UPS system or the building wiring outlet
(shockproof socket outlet) during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.
The UPS system features its own, internal current source (batteries). The UPS output
sockets or output terminals block may be electrically live even if the UPS system is not
connected to the building wiring outlet.
In order to fully disconnect the UPS system, first press the OFF/Enter button to
disconnect the mains.
Prevent no fluids or other foreign objects from inside of the UPS system.

1-5. Maintenance, Service And Faults
The UPS system operates with hazardous voltages. Repairs may be carried out only
by qualified maintenance personnel.
Caution - risk of electric shock. Even after the unit is disconnected from the mains
(building wiring outlet), components inside the UPS system are still connected to the
battery and electrically live and dangerous.
Before carrying out any kind of service and/or maintenance, disconnect the batteries
and verify that no current is present and no hazardous voltage exists in the terminals
of high capability capacitor such as BUS-capacitors.
Only persons are adequately familiar with batteries and with the required
precautionary measures may replace batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.
Caution - risk of electric shock. The battery circuit is not isolated from the input
voltage. Hazardous voltages may occur between the battery terminals and the
ground. Before touching, please verify that no voltage is present!
Batteries may cause electric shock and have a high short-circuit current. Please take
the precautionary measures specified below and any other measures necessary when
working with batteries:
－remove wristwatches, rings and other metal objects
－use only tools with insulated grips and handles.
When changing batteries, install the same number and same type of batteries.
Do not attempt to dispose of batteries by burning them. This could cause battery
explosion.
Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin
and eyes. It may be toxic.
Please replace the fuse only with the same type and amperage in order to avoid fire
hazards.
Do not dismantle the UPS system.

2-2. Install The UPS
For safety consideration, the UPS is shipped out from factory without connecting battery wires.
Before install the UPS, please follow below steps to re-connect battery wires first.
Step 1 Step 2 Step 3
Remove front panel. Re-connect battery wires. Put the front panel back to the
unit.
Rack-mount Installation
Step 1 Step 2
Tower Installation
Step 1 Step 2 Step 3

2-3. Setup The UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension
cords.
Step 2: UPS output connection
For socket-type outputs, there two kinds of outputs: programmable outlets and general
outlets. Please connect non-critical devices to the programmable outlets and critical
devices to the general outlets. During power failure, you may extend the backup time to
critical devices by setting shorter backup time for non-critical devices.
Step 3: Communication connection
Communication port:
USB port RS-232 port Intelligent slot
To allow for unattended UPS shutdown/start-up and status monitoring, connect the
communication cable one end to the USB/RS-232 port and the other to the communication
port of your PC. With the monitoring software installed, you can schedule UPS
shutdown/start-up and monitor UPS status through PC.
The UPS is equipped with intelligent slot perfect for either SNMP or AS400 card. When
installing either SNMP or AS400 card in the UPS, it will provide advanced communication and
monitoring options.
PS. USB port and RS-232 port can’t work at the same time.
Step 4: Network connection
Network/Fax/Phone surge port
Connect a single modem/phone/fax line into surge-protected “IN” outlet on the back panel of
the UPS unit. Connect from “OUT” outlet to the equipment with another modem/fax/phone line
cable.
Step 5: Disable and enable EPO function
Keep the pin 1 and pin 2 closed for UPS normal operation. To activate EPO function, cut the
wire between pin 1 and pin 2.
It’s in closed status for UPS
normal operation.

Step 6: Turn on the UPS
Press the ON/Mute button on the front panel for two seconds to power on the UPS.
Note: The battery charges fully during the first five hours of normal operation. Do not
expect full battery run capability during this initial charge period.
Step 7: Install software
For optimal computer system protection, install UPS monitoring software to fully configure UPS
shutdown. Please follow steps below to download and install monitoring software:
1. Go to the website http://www.power-software-download.com
2. Click ViewPower software icon and then choose your required OS to download the software.
3. Follow the on-screen instructions to install the software.
4. When your computer restarts, the monitoring software will appear as an orange plug icon
located in the system tray, near the clock.
2-4 Battery Replacement

5. Storage and Maintenance
5-1. Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5 years
at 25°C ambient temperature) has been exceeded, the batteries must be replaced. In this
case, please contact your dealer.
Storage
Before storing, charge the UPS 5 hours. Store the UPS covered and upright in a cool, dry
location. During storage, recharge the battery in accordance with the following table:
Storage Temperature Recharge Frequency Charging Duration
-25°C - 40°C Every 3 months 1-2 hours
40°C - 45°C Every 2 months 1-2 hours
Be sure to deliver the spent battery to a recycling facility or ship it to your
dealer in the replacement battery packing material.
