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 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 (or UL-marked for 110/115/120/127 VAC
models) 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 (or UL-marked for 110/115/120/127 VAC
models) 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.
Temperature Rating - Units are considered acceptable for use in a maximum
ambient of 40°C (104°F).
For Pluggable Equipment - The socket-outlet shall be installed near the equipment
and shall be easily accessible.
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.

2
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!
Caution - Do not dispose of batteries in a fire. The batteries may explode.
Caution - Do not open or mutilate batteries. Released electrolyte is harmful to the
skin and eyes. It may be toxic.
a) 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 watches, rings, or other metal
objects.
b) Use tools with insulated handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of batteries.
e) Disconnect charging source and load prior to installing or maintaining the
battery.
f) Remove battery grounds during installation and maintenance to reduce
likelihood of shock. Remove the connection from ground if any part of the
battery is determined to be grounded.
When changing batteries, install the same number and same type of batteries.

2-3. Setup the UPS
Before installing the UPS, please read below to select proper location to install UPS.
1. UPS should be placed on the flat and clean surface. Place it in an area away from vibration,
dust, humidity, high temperature, flammable liquids, gases, corrosive and conductive
contaminants. Install the UPS indoors in a clean environment, where it is away from window
and door. Maintain minimum clearance of 100mm in the bottom of the UPS to avoid dust and
high temperature.
2. Maintain an ambient temperature range of 0ºC to 45ºC for UPS optimal operation. For every
5ºC above 45ºC, the UPS will derate 12% of nominal capacity at full load. The highest working
temperature requirement for UPS operation is 50ºC.
3. It’s required to maintain maximum altitude of 1000m to keep UPS normal operation at full
load UPS. If it’s used in high altitude area, please reduce connected load. Altitude derating
power with connected loads for UPS normal operation is listed as below:
4. Place UPS:
It’s equipped with fan for cooling. Therefore, place the UPS in a
well-ventilated area. It’s required to maintain minimum clearance
of 100mm in the front of the UPS and 300mm in the back and two
sides of the UPS for heat dissipation and easy-maintenance.

6
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
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:
USBport 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.
Step 4: Disable and enable EPO function
This UPS is equipped with EPO function. By default, the UPS is delivered from factory with Pin
1 and pin 2 closed (a metal plate is connected to Pin 1 and Pin2) for UPS normal operation. To
activate EPO function, remove two screws on EPO port and green connector will be removed.
Note: The EPO function logic can be set up via LCD setting. Please refer to program 8 in UPS
setting for the details.
Step 5: 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 6: Install software
For optimal computer system protection, install UPS monitoring software to fully configure UPS
shutdown. Use supplied RS-232 or USB communication cable to connect RS-232/USB port of
UPS and RS-232/USB port of PC. Then, follow below steps to install monitoring software.
1. Insert the included installation CD into CD-ROM drive and then follow the on-screen
instructions to proceed software installation. If there no screen shows 1 minute after
inserting the CD, please execute setup.exe file for initiating software installation.
2. Follow the on-screen instructions to install the software.
3. When your computer restarts, the monitoring software will appear as an orange plug icon
located in the system tray, near the clock.
It’s in closed status for UPS
normal operation as default.
To activate EPO function, remove
these two screws.

voltage regulation range but lower than high
loss point, the buck AVR will be activated.
Boost mode
when AC is
normal.
When the input voltage is lower than the
voltage regulation range but higher than low
loss point, the boost AVR will be activated.
Battery mode
When the input voltage is beyond the
acceptable range or power failure, UPS will
backup power from battery and alarm is
sounding every 10 seconds.
