3.3 STORAGE
3.3.1 Storage of the UPS
The UPS is carefully packed for transport and storage so that it is in perfect condition when installed.
Never leave a UPS outside the building and don’t store other packages on the top of the UPS.
It is advisable to store the UPS in its original package in a dry, dust-free room, away from chemical
substances, and with a temperature range not exceeding -13°F (-25°C) to 131°F (55°C).
In case the battery is included please refer to Section 3.3.2.
Some important functions of the UPS, such as the customized functions, are defined by parameters
stored in a RAM memory.
A small backup battery located on the Control Unit board supplies the RAM.
If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorized
Service Center before putting the UPS into operation.
3.3.2 Storage of Battery
When the delivery includes a maintenance free Battery, keep in mind that they are subject to self-
discharge and therefore you must recharge the Battery.
The storage time without Battery recharge depends on the temperature of the storage site.
The optimal temperature for Battery storage is 68°F (20°C) to 77°F (25°C) and shall never exceed the
range -4°F (-20°C) to 104°F (40°C).
Recharge stored maintenance free Battery every:
6 months when the storage temperature is 20°C (68°F)
3 months when the storage temperature is 30°C (86°F)
2 months when the storage temperature is 35°C (95°F)

3.4 PLACE OF INSTALLATION
3.4.1 UPS location
NOTE !
A QUALIFIED ELECTRICAL CONTRACTOR must carry out the installation and cabling
of the UPS.
It is important to have a clean, dust-free environment provided with proper ventilation and air-
conditioning to keep the ambient temperature within the specified operating range.
The recommended air inlet temperature is from 68°F (20°C) to 77°F (25°C) (max. 104°F / 40°C).
Refer to Section 3.5.
Check for sufficient floor load capacity before installing the UPS and the Battery.
Refer to Section 3.1.1.
The inverter cabinet and rectifier cabinet must be installed on level floor.
For Battery installation follow the local codes and the recommendation of the battery supplier.
NOTE !
Temperature is very important for valve-regulated batteries (maintenance free).
Operation at temperatures higher than 77°F (25°C) will reduce battery life.
The SG Series UPS can radiate radio frequency energy.
Although some RFI filtering is inherent to the UPS there is no guarantee that the UPS will not influence
sensitive devices such as cameras and monitors that are positioned close by.
If interference is expected, the UPS should be moved away from the sensitive equipment.

3.4.2 Battery location
Batteries require a well-ventilated room with controlled temperature to obtain reliable operation.
The Battery can be installed immediately adjacent to the UPS (left or right side) or remotely from the
UPS.
If the Battery is installed remotely from the UPS, a wall mounted DC disconnect device must be installed
within line-of-site to both the UPS and the Battery.
The optimal room temperature for Battery storage is 68°F (20°C) to 77°F (25°C) and shall never exceed
the range -4°F (-20°C) to 104°F (40°C).
The life of valve-regulated batteries will be reduced by 50% for each additional 18°F (10°C) that the
Battery ambient temperature is above 77°F (25°C).
The Battery System associated with larger UPS is usually either rack mounted or installed in multiple
Battery Cabinets.
Installation and assembly must be made according to the local standards and Battery System
manufacturer‘s recommendations.
The Battery Circuit Breaker or Battery Fuse Box must be mounted as near as possible to the Battery.
WARNING !
Battery installation and connection must be performed by QUALIFIED PERSONNEL
only.
Read all safety instructions before proceeding with the installation.

3.5 VENTILATION AND COOLING
Fig. 3.5-1 Installation on solid floor
The heat produced by the UPS is transferred
to the environment by its ventilation.
Air inlets for UPS ventilation are located on the
front and bottom of the UPS, while air outlets
are on top of the cabinet.
A suitable ventilation or cooling system must
be installed to extract the heat from the UPS
room.
NOTE !
Do not put anything on the top of the cabinet.
Air filtration systems could be required when the UPS operates in a dirty environment.
Contact your Dealer or the nearest Service Center for appropriate solutions.
In order to prevent overheating of the UPS, the available air intake flow rate must exceed the total air
exhaust flow rate requirement of the UPS system.
The below tables indicate the heat dissipation at full Load at PF = 0.9 lag. and charged Battery, up to
3,280 ft (1,000 m) altitude, for cooling air 77°F (25°C) to 86°F (30°C).
