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.
1
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. Installation and setup
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.

2-2. Setup the UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
The power cord is supplied in the UPS package.
Step 2: 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 2.1mm2 power cords for 3KVA (200/208/220/230/240VAC models).
Suggest using AWG12-10 or 3.3mm2-5.3mm2 power cords for 3KVA
(100/110/115/120/127VAC models). Please also install a 2-port breaker 40A for 3KVA
100/110/115/120127VAC models and 20A, 250V for 3KVA 200/208/220/230/240VAC models
between the mains and AC input of UPS 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 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: 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 5: 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.
Step 6: External battery connection
Follow the right chart to make external battery connection.
