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.
•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.
•Prevent no fluids or other foreign objects from inside of the UPS system.

EN
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 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. 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 attached to the UPS. The input plug is a NEMA 5-15P.
Step 2: UPS output connection
There are two kinds of output receptacles: programmable outlets and general outlet. 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 Dry contact 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 pin assignment for dry contact is listed as below:
Condition
Pin status

No
Low battery.
Pin 3 and Pin 9 are connected.
Pin 3 and Pin 1 are connected.
Output is abnormal.
Pin 7 and Pin 8 are connected.
Pin 7 and Pin 5 are connected.
Battery mode.
Pin 2 and Pin 6 are connected.
Pin 2 and Pin 4 are connected.
The UPS is equipped with intelligent slot perfect for SNMP card. When installing with SNMP card
in the UPS, it will provide advanced communication and monitoring options.

Step 4: Disable/Enable ROO/RPO function
Contact open: UPS shuts down.
Contact closed: UPS start-up (UPS is connected to AC
power and AC power is available).
Note: The local ON/OFF control by pressing On/Off
button overrides the remote-control function.
Contact open: UPS shuts down and Fault LED (3) will
be ON.
To return to normal operation, de-activate external
remote contact (Fault LED (3) will be OFF) and restart
the UPS by pressing button.
Step 5: Turn on/off the UPS
Press the ON/OFF button on the front panel for two seconds to power on the UPS.
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.

4. Troubleshooting
If the UPS system does not operate correctly, please solve the problem by using the table
below.
Symptom
Possible cause
Remedy
No indication and alarm even
though the mains is normal.
The AC input power is not
connected well.
Check if input power cord
firmly connected to the
mains.
The AC input is connected
to the UPS output.
Plug AC input power cord
to AC input correctly.
The alarm is sounding twice
every second.
UPS is overload
Remove excess loads
from UPS output.
After repetitive overloads,
the UPS is locked in the
Bypass mode. Connected
devices are fed directly by
the mains.
Remove excess loads
from UPS output first.
Then, shut down the UPS
and restart it.
5. Storage and Maintenance
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
