1. 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
oCondensation 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.
oDo not install the UPS system near water or in moist environments.
oDo not install the UPS system where it would be exposed to direct sunlight or
near heater.
oDo not block ventilation holes in the UPS housing.
1.3. Installation
oDo not connect appliances or devices which would overload the UPS system
(e.g. laser printers) to the UPS output sockets.
oPlace cables in such a way that no one can step on or trip over them.
oDo not connect domestic appliances such as hair dryers to UPS output
sockets.
oThe UPS can be operated by any individuals with no previous experience.
oConnect the UPS system only to an earthed shockproof outlet which must be
easily accessible and close to the UPS system.
oPlease use only VDE-tested, CE-marked (or UL-marked for
100/110/115/120/127 VAC models) mains cable (e.g. the mains cable of your

Page | 3
computer) to connect the UPS system to the building wiring outlet
(shockproof outlet).
oPlease use only VDE-tested, CE-marked (or UL-marked for
100/110/115/120/127 VAC models) power cables to connect the loads to the
UPS system.
oWhen 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.
oTemperature Rating - Units are considered acceptable for use in a maximum
ambient of 40 °C (104 °F).
oFor Pluggable Equipment - The socket-outlet shall be installed near the
equipment and shall be easily accessible.
1.4. Operation
oDo 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.
oThe 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.
oIn order to fully disconnect the UPS system, first press the OFF/Enter button
to disconnect the mains (commercial power).
oPrevent 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.
oCaution - Risk of electric shock. Even after the unit is disconnected from the
mains (commercial power), components inside the UPS system are still
connected to the battery and electrically live and dangerous.
oBefore 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.
oOnly 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.
oCaution - Risk of electric shock. The battery circuit is not isolated from the

Page | 4
input voltage. Hazardous voltages may occur between the battery terminals
and the ground. Before touching, please verify that no voltage is present!
oDo not dispose of batteries in a fire. The batteries may explode.
oDo not open or mutilate batteries. Released electrolyte is harmful to the skin
and eyes. It may be toxic.
oBatteries 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:
1) Remove watches, rings, or other metal objects.
2) Use tools with insulated handles.
3) Wear rubber gloves and boots.
4) Do not lay tools or metal parts on top of batteries.
5) Disconnect charging source and load prior to installing or
maintaining the battery.
6) Remove battery grounds during installation and maintenance to
reduce likelihood of shock.
7) Remove the connection from ground if any part of the battery is
determined to be grounded.
oWhen changing batteries, install the same number and same type of batteries
or battery packs.
For UPS with internal mounting Batteries
oInstructions shall carry sufficient information to enable the replacement of the
battery with a suitable manufacturer and catalogue number.
oSafety instructions to allow access by Service Personnel shall be stated in the
installation/service handbook.
oIf batteries are to be installed by Service Personnel, instructions for
interconnections, including terminal torque, shall be provided.
oDo not attempt to dispose of batteries by burning them. This could cause
battery explosion.
oDo not open or destroy batteries. Escaping electrolyte can cause injury to the
skin and eyes. It may be toxic.
oPlease replace the fuse only with the same type and amperage in order to
avoid fire hazards.
oDo not dismantle the UPS system.

2.4. Setup the UPS
Before installing the UPS, please read below to select proper location
to install UPS.
1. UPS should be placed on the flat and clean surface. Place it in an area away from
vibration, dust, humidity, high temperature, flammable liquids, gases, corrosive and
conductive contaminants. Install the UPS indoors in a clean environment, where it is
away from window and door. Maintain minimum clearance of 100mm in the bottom
of the UPS to avoid dust and high temperature.

2. Maintain an ambient temperature range of 0 ºC to 45 ºC for UPS optimal operation.
For every 5ºC above 45ºC, the UPS will derate 12% of nominal capacity at full load.
The highest working temperature requirement for UPS operation is 50 ºC.
3. It is necessary to maintain a maximum altitude of 1.000 meters to maintain normal
operation of the UPS at full load. If used in high altitude areas, reduce the connected
load. The decrease of the energy with respect to the altitude are describe below:
ALTITUDE (m)
Derating factor [1]
1.000
1.500
2.000
2.500
3.000
3.500
4.000
4.500
5.000
1.0
0.95
0.91
0.86

0.74
0.7
0.67
Based on density of dry air = 1.225 kg/m3 at sea-level +15 °C.
[1] –Since fans lose efficiency with altitude, forced air-cooled equipment will have a smaller derating.
4. Place UPS:
The equipment has a fan for cooling. Therefore, place the UPS in a well-
ventilated area. It’s required to maintain minimum clearance of 100mm in
the front of the UPS and 300mm in the back and two sides of the UPS for
heat dissipation and easy-maintenance.
