1. Important Safety Warning
SAVE THESE INSTRUCTIONS - This manual contains important instructions that should be followed during installation
and maintenance of the UPS and batteries.
Please comply with all warnings and operating instructions in this manual strictly. Do not operate this unit before
reading through all safety information and operating instructions carefully.
1-1. Transportation
l Please transport the UPS system only in the original package to protect against shock and impact.
1-2. Preparation
l 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.
l Do not install the UPS system near water or in moist environments.
l Do not install the UPS system where it would be exposed to direct sunlight or near heater.
l Do not block ventilation holes in the UPS housing.
1-3. Installation
l Do not connect appliances or devices which would overload the UPS system (e.g. laser printers) to the UPS
output sockets.
l Place cables in such a way that no one can step on or trip over them.
l Do not connect domestic appliances such as hair dryers to UPS output sockets.
l The UPS can be operated by any individuals with no previous experience.
l Connect the UPS system only to an earthed shockproof outlet which must be easily accessible and close to
the UPS system.
l Please use only VDE-tested, CE-marked (UL-marked for UPS9A models) mains cable (e.g. the mains cable
of your computer) to connect the UPS system to the building wiring outlet (shockproof outlet).
l Please use only VDE-tested, CE-marked (UL-marked for UPS9A models) power cables to connect the loads
to the UPS system.
l 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.
l Temperature Rating - Units are considered acceptable for use in a maximum ambient of 40°C (104°F).
l For Pluggable Equipment - The socket-outlet shall be installed near the equipment and shall be easily
accessible.
l CAUTION: The unit is heavy. Lifting the unit requires a minimum of two people.
l Batteries with minimum case flame rating V-2 are intended for use in a computer room as defined in the
Standard for the Protection of Information Technology Equipment, ANSI/NFAP 75. Batteries with case
flame rating HB are not intended for use in a computer room. (US installations only.)

1-4. Operation
l 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.
l 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.
l In order to fully disconnect the UPS system, first press the OFF/Enter button to turn off the unit.
l Prevent fluids or other foreign objects from inside of the UPS system.
l The EPO and USB circuits are an IEC 60950-1 safety extra low voltage (SELV) circuit. This circuit must be
separated from any hazardous voltage circuits by reinforced insulation.
1-5. Maintenance, service and faults
l The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified
maintenance personnel.
l 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.
l 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.
l To avoid electrical shock, turn off the unit and unplug it from the AC power source before servicing the
battery
l Only persons 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.
l 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!
l Caution - Do not dispose of batteries in a fire. The batteries may explode.
l Caution - Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may
be toxic.
l A battery can may cause 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.
f) Determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock
can be reduced if such grounds are removed during installation and maintenance.

l When changing batteries, install the same number and same type of batteries or battery packs.
l Please replace the fuse only with the same type and amperage in order to avoid fire hazards.
l Do not dismantle the UPS system.
l WARNING: This is a category C2 UPS product. In a residential environment, this product may cause radio
interference, in which case the user many be required to take additional measures. (only for CE models)
l NOTE: This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio communications. Operation of this
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
l WARNING: Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.

This UPS can be either displayed on the desk or mounted in the 19” rack chassis. Please choose proper installation to
position this UPS.
UPS Rackmount Installation with 4-point Rail Kit
Step 1: Mount the 4-point rail kit to the rack. Use the (8) 10-32 screws provided to mount left and right support rails
(front and rear).
Step 2:
Attach the mounting brackets to the UPS. CAUTION—DO NOT use mounting brackets to lift the UPS; brackets
are only to secure it to the rack.

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, gas, 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. Place UPS: It’s equipped with 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.
Step 1: External battery connection
For safety consideration, the UPS is shipped out from factory without connecting battery wires.
Before connecting to external batteries, it’s required to have the internal battery wire disconnected.
Follow the below steps to make external battery connection.
1. Turn off UPS and remove power plug from the mains.
2. Remove front panel and disconnect internal battery wire.
3. Remove the cover of the external battery connector by using a screwdriver.
4. Plug the battery cable into the external battery connector of the UPS and the battery pack(s).
Note: If you have multiple battery packs available, connect them serially. An example is shown in the diagram
below (connecting the second battery connector of the first battery pack to the first battery connector of the
second battery pack).
