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.

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!
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. Installation and setup
NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is
damaged. Please keep the original package in a safe place for future use.

This UPS can be mounted in the 19” rack chassis. Please follow below steps to position this UPS.
Step 1 Step 2

6
2-3. Setup the UPS
Step 1: External battery connection (Only for long-run
model)
This UPS is not including batteries. Please connect external
batteries as chart.
Step 2: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle
only. Avoid using extension cords.
For 200/208/220/230/240VAC models: The power cord is
supplied in the UPS package.
For 100/110/115/120/127VAC models: The power cord is
attached to the UPS. The input plug is a NEMA 5-15P for 1K model and NEMA 5-20P for 2K
model.
Step 3: UPS output connection
For socket-type outputs, simply connect devices to the outlets.
For terminal-type input or outputs, please follow below steps for the wiring configuration:
a) Remove the small cover of the terminal block
b) Suggest using AWG14 or 2.1mm2power cords for 3KVA (200/208/220/230/240VAC
models). Suggest using AWG12-10 or 3.3mm2-5.3mm2power cords for 3KVA
(100/110/115/120/127VAC models). Please also install a circuit breaker (40A) between
the mains and AC input of UPS in 3KVA (100/110/115/120127VAC models) for safety
operation.
c) Upon completion of the wiring configuration, please check whether the wires are
securely affixed.
d) Put the small cover back to the rear panel.
Step 4: 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 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.

7
Step 6: Install software
For optimal computer system protection, install UPS monitoring software to fully configure UPS
shutdown. You may insert provided CD into CD-ROM to install the monitoring software. If not,
please follow steps below to download and install monitoring software from the internet:
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.

3-6. Operating Mode Description
Operating mode
Description
LCD display
Standby mode
UPS is powered off and no output supply
power, but still can charge batteries.
Online mode
When the input voltage is within
acceptable range, UPS will provide pure
and stable AC power to output. The UPS
will also charge the battery at online
mode.
ECO mode
Energy saving mode:
When the input voltage is within voltage
regulation range, UPS will bypass
voltage to output for energy saving.
Converter mode
When input frequency is within 40 Hz to
70 Hz, the UPS can be set at a constant
output frequency, 50 Hz or 60 Hz. The
UPS will still charge battery under this
mode.

17
Battery mode
When the input voltage is beyond the
acceptable range or power failure and
alarm is sounding every 4 second, UPS
will backup power from battery.
Battery test
mode
UPS will turn off charger and check if
battery and DC/DC are normal.
Bypass mode
When input voltage is within acceptable
range but UPS is overload, UPS will enter
bypass mode or bypass mode can be set
by front panel. Alarm is sounding every
10 second.
Fault mode
When a fault has occurred, the ERROR
icon and the fault code will be displayed.
