1. Important Safety Warnings
Please strictly comply with all warnings and operating instructions in this manual. Save this manual and
carefully read 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
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 to 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 a 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 individuals with no previous experience.
•The UPS can be operated in TN & TT power distribution.
•Connect the UPS system only to an earthed shockproof outlet which must be easily accessible and
close to the UPS system.
•Please use only UL-tested, UL-marked power cables to connect the loads to the UPS system.
•When installing the equipment, 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.
•CAUTION: The unit is heavy. Lifting the unit requires a minimum of two people.
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 earth 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 terminal blocks 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 and disconnect the
mains.
•Prevent fluids or other foreign objects from getting inside the UPS system.
•The EPO, RS-232 and USB circuits are IEC 60950 safety extra low voltage (SELV) circuits. This
circuit must be separated from any hazardous voltage circuits by reinforced insulation.

Page | 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 capacitors
such as BUS-capacitors.
•To avoid electrical shock, turn off the unit and unplug it from the AC power source before servicing
the battery.
•Only persons that 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, verify
that no voltage is present!
•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.
•When replacing batteries, replace with the same type and number of batteries or battery packs.

•Do not dismantle the UPS system.
•WARNING - A battery can present a risk of electrical shock and high short-circuit current. The
following precautions should be observed when working on batteries:
a) 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 prior to connecting or disconnecting battery
terminals.
f) Determine if battery is inadvertently grounded. If inadvertently grounded, remove source
from ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock can be reduced if such grounds are removed during
installation and maintenance.

2.2 Operating principle
The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger,
DC-to-DC converter, battery, dynamic bypass and UPS output.
2.3 Install the UPS
For safety consideration, the UPS is shipped out from factory without connecting battery wires. Before
installing the UPS, please follow the below steps to re-connect battery wire.
Step 1 Step 2 Step 3
Step 1: Remove front panel.
Step 2: Remove battery panel and re-connect battery wire.
Step 3: Put battery panel and cover back to the unit.
This UPS can be either displayed on the desk or mounted in the 19” rack chassis. Please choose proper
installation to position this UPS.

NOTE: When installing the UPS or battery pack with feet, keep 2.76in distance from the edge of the unit.

Page | 7
2.4 Setup the UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
CAUTION: For 1 and 2 kVA models, to reduce the risk of fire, connect only to a circuit provided with 20
amperes maximum branch circuit overcurrent protection in accordance with the National Electric Code,
ANSI/NFPA 70.
CAUTION: For 3 kVA models, to reduce the risk of fire, connect only to a circuit provided with 30 amperes
maximum branch circuit overcurrent protection in accordance with the National Electric Code, ANSI/NFPA
70.
Step 2: UPS output connection
There two kinds of outputs: programmable outlets and general outlets. 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 one end of the
communication cable to the USB/RS-232 port and the other end to the communication port of your PC.
With the monitoring software installed, you can perform these operations:
•Remote Shutdown of UPS
•Send shutdown commands to remote computers
•Remotely set parameters of the UPS
•Set-up the number of battery strings connected
•Set-up voltage and frequency ranges
See manual for monitoring software for details.
The UPS is equipped with an intelligent slot perfect for either a SNMP or an AS400 card. Installing either a
SNMP or AS400 card in the UPS will provide advanced communication and monitoring options.
NOTE: 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.

1 and pin 2.
Step 6: External battery connection
Connect one end of external battery cable to UPS unit and the other end to battery pack. See below chart
for detailed connection.
CAUTION: Connection to External Battery shall be installed by SERVICE PERSONNEL only.
CAUTION – Risk of fire hazard.
Step 7: 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 8: Install software
Install UPS monitoring software to fully configure UPS shutdown. Follow the 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.
