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.
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 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 UL-tested, UL-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.
The EPO, RS-232 and USB circuits are an IEC 60950 safety extra low voltage (SELV)
1
circuit. This circuit must be separated from any hazardous voltage circuits by reinforced
insulation.
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!
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.
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.

2-2. Operating principle
The operating principle of the UPS is shown as below
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 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.

2-4. Setup the UPS
Step 1: External battery connection (for X models only)
Connect one end of external battery cable to UPS unit and the other end to battery pack. See
below chart for detailed connection.
Step 2: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
CAUTION: Please also install a UL-approved circuit breaker (40A) between the mains and AC
input in 3K model for safety operation.
Step 3: UPS output connection
There two kinds of outputs: programmable outlets and general outlets. 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.
