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.
• Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS
system.
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).
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 button to disconnect the
mains.
• 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

‐4‐
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.

reach to 11.0V/pcs, The segment 1 cut off battery voltage can be set by soft tool by RS232
port.
2. Segment 2 outlets: connect to mission-critical loads.
2-2. Install The UPS
For safety consideration, the UPS is shipped out from factory without connecting battery wires
Before install the UPS, please follow below steps to re-connect battery wires first.

Remove front panel. Re-connect battery wires. Fix front panel
2-3. Setup The UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only.
Step 2: UPS output connection
There two segments of outputs: segment 1 outlets and segment 2 outlets. Please connect
non-critical devices to the segment 1 outlets and critical devices to segment 2 outlets. During
power failure, you may extend the backup time to critical devices by setting shorter backup time
for non-critical devices.

Step 3: Communicationconnection
Communication ports:
USB port RS-232port 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 orAS400 card in the UPS, it will provide advanced communication and monitoring
options.
Step 4: Disable and enable EPO function
Keep the pin 1 and pin 2 closed for UPS normal operation. To activate EPO function, cut the
wire between pin 1 and pin 2.
Step 5: Turn on the UPS
Press the ON 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. Please use software CD or go to website http://www.megatec.com.tw/Download.htm
2-4 Battery Replacement
NOTICE: This UPS is equipped with internal batteries and user can replace the batteries without
shutting down the UPS or connected loads.(hot-swappable battery design) Replacement is a
safe procedure, isolated from electrical hazards.
CAUTION!! Consider all warnings, cautions, and notes before replacing batteries.
Note: Upon battery disconnection, equipment is not protected from power outages.

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.
EPO displayed on LCD and alarm
is sounding. EPO function is activated. Set the circuit in close
position to disable EPO
function.

The UPS shut down
automatically because short
circuit occurs on the UPS
output.
Check output wiring and if
connected devices are in
short circuit status.

08,09 on LCD display and alarm is
continuously sounding.
A UPS internal fault has
occurred. Contact your dealer
Battery backup time is shorter than
nominal value
Batteries are not fully
charged
Charge the batteries for at
least 5 hours and then check
capacity. If the problem still
persists, consult your dealer.

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.
» Be sure to deliver the spent battery to a recycling facility or ship it to your
dealer in the replacement battery packing material.
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 1-2 hours
