3.3. Important Notice for UPS
• The equipment may only be installed and commissioned by authorized LEGRAND UPS Technical Service Personnel.
• This manual contains important instructions that you should follow during installation and maintenance of the
UPS and batteries. Please read all instructions before installing the equipment and save this manual for future
reference.
• Not obeying the instructions written on this manual which may result with possible injury of the operator or
damage of the equipment.
• The equipment shall be packed properly during transportation and proper equipment should be used for
transportation. Never transport in horizontal position.
• The UPS must always stands in a vertical position. Make sure that the oor can support the weight of the system.
• Connect the PE ground connector before connecting any other cable.
• Because of “LITTLE LEAKAGE CURRENTS” generated by EMI Filter of the UPS, it is necessary to double ensure if the
earth of the UPS is properly grounded before AC mains is connected with.
• UPS is designed for indoor use. To reduce the risk of re or electric shock, install this UPS in a temperature and
humidity controlled indoor environment, free of conductive contaminants. Ambient temperature must not exceed
40°C (104°F). Do not operate near water or excessive humidity (95% maximum without condensation).
• UPS requires 1Ph-N+PE input connection.
• Neutral system: refer to Section 5.3.1.5 Output Connection.
• Even when connections removed, residual voltages of capacitors and/or high temperature may exist on
connection terminals and inside the UPS. Before working on terminals, check between all the terminals included
PE that no hazardous voltages exist.
• The connections shall be made with cables of appropriate cross-section in order to prevent the risk of re. All
cables shall be of insulated type and shall not be laid out on the walking path of the persons.
• According to IEC 62040-2; this is a category C2 UPS product. In a residential environment, this product may cause
radio interference, in which case the user may be required to take additional measures.
• Contact your local recycling or hazardous waste center for information on proper disposal of the used battery or
UPS.
• Make sure that the UPS is not overloaded to provide a higher quality supply to the loads.
• In case of an extraordinary situation (damaged body, cabinet or connections, penetration of foreign materials
into the body or cabinet etc.) de-energize the UPS immediately and consult to the LEGRAND Technical Assistance
Center.
• When used for particular applications such as life support systems or any other application where product failure
is likely to cause substantial harms to person, we would advise you to contact LEGRAND UPS to conrm the ability
of these products to meet the requested level of safety, performance, reliability and compliance with applicable
laws, regulations and specications.

3.4. Important Notice for Battery
• The batteries may only be installed and commissioned by authorized LEGRAND UPS Technical
Service Personnel.
• Make sure that the battery qty is proper for the unit and they are same type and capacity. Otherwise
danger of explosion and re is within the bounds of possibility.
• Do not dispose of batteries in a re. The batteries may explode.
• Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.
• In case of electrolyte in contact with skin, immediately wash the contaminated skin with water.
• Replaced batteries must be disposed of at authorized battery waste disposal centers.
• A battery can present risk of electric shock and high short circuit currents.
The following precautions should be observed when working on batteries;
• Remove rings, watches, necklaces, bracelets and all metal objects.
• Only use tools with insulated handles.
• Wear rubbers gloves and a rubber apron when handling batteries.
• Do not lay tools or metal parts on top of batteries.
• Eye protection should be worn to prevent injury from accidental electrical arcs.
• Before a maintenance or repair work on the UPS;
• Switch the input and output circuit breakers (Q1 and Q2) to “OFF” position.
• Switch battery circuit breakers (Q3) to “OFF” position.
• If UPS has external batteries; switch the circuit breakers (F5) of the battery cabinet(s) to “OFF” position.
• Determine if the battery is inadvertently grounded. If inadvertently grounded; remove source of ground.
Contact with any part of a grounded battery can result in electrical shock.
3.5. Emergency interventions
The following information is of a general nature. For specic interventions please consult the laws existing
in the country where the equipment is installed.
First aid interventions
If any rst aid intervention is required, comply with company rules and traditional procedures.
Fire-prevention measures
Never use water to extinguish re but only the extinguishers designed specically for electronic equipment
or battery res.
12
4.2. Placement
• UPS is not designed for outdoor application.
• The equipment and the batteries should not be exposed to direct sunlight or placed near to a heat source.
• Recommended operating temperature and humidity values are listed on the Appendix-3 Technical
Specications section. To provide the required environmental condition.
• Avoid dusty environments or areas where dust of conductive or corrosive materials is present.
• The connection and the circuit breakers are at the back side of UPS. Leave at least 30 cm at the back side
of the UPS for maintenance.
• Air outlets of the UPS are present on the front and back sides. Leave at least 30 cm at the front and back
side of the UPS for ventilation.
• To eliminate any overheating of the UPS, keep all ventilation openings free from obstruction, and do not
store “things” on top of the UPS.
• Even though the operating temperature of the UPS and batteries are between 0-40 °C, It is suggested to
provide an environment temperature between 20-25°C to get maximum performance from the UPS and
batteries.
• Advised environmental humidity condition is between 30%~90% (non-condensing).
The UPS must be placed and stand in a vertical position throughout the transportation.
Use suitable equipment to remove the UPS from the pallet.
The equipment shall be packed properly during transportation. Therefore it is
recommended to keep the original package for future need.
Optimal battery life time is reached when battery ambient temperature is kept
between 15°C and 25°C. Operating battery at 30°C ambient temperature compared
to 20°C will divide by factor 2 battery life time. Room thermal management as
specied above is then necessary to avoid battery life time reduction. The Battery
warranty does not apply if the temperature in the room exceeds 25°C.
All packing material must be recycled in compliance with the laws in force in the
country where the system is installed.
