3. IMPORTANT SAFETY WARNING
Please read the following instructions carefully before installing the unit and strictly comply with all the
warnings and operating instructions herein. Save this manual for future reference and do not operate this unit
before reading through all safety information and operating instructions carefully.
3-1. Transportation
• Please transport the UPS system in the original package only to protect against shock and impact.
3-2. Preparation
• Condensation may occur if the UPS system is moved directly from a 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 acclimatize 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.
3-3. Installation
• Do not connect appliances or devices which would overload the UPS system (e.g. laser printers) to
the UPS output sockets.
• Do not place cables in such a way that 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 individual with no previous experience.
• Connect the UPS system to an earthed shock-proof outlet which must be easily accessible and
close to the UPS system.
• Use only VDE-tested, CE-marked, ISI-marked mains cable (e.g. the mains cable of your computer)
to connect the UPS system to the building wiring outlet (shock-proof outlet).
• Use only VDE-tested, CE-marked, ISI-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 3.5 mA.
• UPS is designed for linear load, worst case inductive resistive load.
3-4. Operation
• Do not disconnect the mains cable on the UPS system or the building wiring outlet
(shock-proof socket outlet) during operations since this would cancel the protective earthing
of the UPS system and 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 fluids or other foreign objects from entering the UPS system.
3-5. 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.
They might be 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 exist in the terminals of high capability
capacitor such as BUS-capacitors.
• Only people adequately familiar with batteries and with the required precautionary measures
may replace batteries and supervise operations. Unauthorized persons must be kept 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 object
• 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 electrolytes can be toxic and cause injury to the skin and eyes.
• Replace the fuse with the same type and amperage in order to avoid fire hazards.
• Do not dismantle the UPS system.
• Connect UPS to short-circuit protected building wiring.
• The UPS system has internal fuses on both DC & AC inputs. Those devices do not protect the
up stream cables connected to DC & AC inputs and upstream breakers or fuses shall be set up
in accordance with AC & DC wires ratings to meet the local national electrical code standard.

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 in online mode.
ECO mode
Energy saving mode: When the input voltage
is within voltage regulation range, UPS will
bypass voltage to output for energy saving.
Frequency
converter mode
When input frequency is within 40 Hz. to 70
Hz, the UPS can be set at a constant output
frequency, 50 Hz. or 60 Hz. The UPS will still
charge battery under this mode.
Battery mode
When the input voltage is beyond the
acceptable range or power failure and alarm
sounds every 4 seconds, UPS will backup
power from battery.
Bypass mode
When input voltage is within the acceptable
range but UPS is overloaded, UPS will enter
Bypass mode or Bypass mode can be set by
front panel. Alarm sounds every 10 seconds.
Standby mode UPS is powered off and no output supply
power, but still can charge batteries.
