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 packaging 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
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
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 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.

Maruson Technology Corporation 2 ULTIMA RACK/TOWER SERIES 1K-3KVA |
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 are 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.

2.2. Installing 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.
Step 1
Step 2
Step 3
Remove front panel.
Connect the AC input and
re-connect battery wires.
Put the front panel 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.

Step 3
2.3. Setup the UPS
Step 1: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension
cords.
Step 2: UPS output connection
For socket-type outputs, there two kinds of outputs: programmable outlets and general outlets.

Maruson Technology Corporation 5 ULTIMA RACK/TOWER SERIES 1K-3KVA |
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 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 the 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.
NOTE: USB port and RS-232 port cannot be used 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.
Step 5: Disable and enable EPO function
Keep pin 1 and pin 2 closed for UPS normal operation. To activate EPO function, cut the wire
between pin 1 and pin 2.
Step 6: 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 7: Installing software
For optimal computer system protection, install UPS monitoring software to fully configure UPS
shutdown. Please follow steps below to download and install monitoring software:

On-line
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
On-line mode.
ECO mode
(Efficiency
Corrective
Optimizer)
When the input voltage is within
setting range (±3%Vo max), UPS will
bypass voltage to output for energy
saving. PFC and INVERTER are still
active at this mode.
AECO mode
(Advanced
Efficiency
Corrective
Optimizer)
When the input voltage is within
setting range (±3%Volt. max), UPS
will bypass voltage to output for
energy saving. PFC and INVERTER
are off at this mode.
Frequency
Converter
mode
( Rack )
When input frequency is within 40 Hz
to 70 Hz, the UPS can be set at a
constant output frequency at 50 Hz or
60 Hz. The UPS will still charge the
battery under this mode.
Battery
mode
When the input voltage is beyond the
acceptable range or during power
failure, the alarm will beep every 4
seconds. UPS will provide backup
power from battery.
Bypass
mode
When input voltage is within
acceptable range but UPS is
overloaded, UPS will enter Bypass
mode. Bypass mode can also be set
by the front panel. Alarm is will beep
every 10 seconds.

Maruson Technology Corporation 17 ULTIMA RACK/TOWER SERIES 1K-3KVA |
Standby
mode
UPS is powered off without output
power and the battery will continue
charging.
Fault mode
The UPS is in Fault mode when no
output power is supplied from the
UPS and the fault icon flashes on the

connected well.
Fault code “27” is displayed, the
icon is flashing on the LCD
display and alarm is continuously
beeping.
Battery voltage is too high
or the charger is fault.
Contact your dealer.
Fault code “28” is displayed, the
icon is flashing on LCD
display and alarm is continuously
beeping.
