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 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).
Recharge stored maintenance free battery every:
6 months when the storage temperature is 68°F (20°C)
3 months when the storage temperature is 86°F (30°C)
2 months when the storage temperature is 95°F (35°C)

3.4 PLACE OF INSTALLATION
3.4.1 UPS location
WARNING !
A QUALIFIED ELECTRICAL CONTRACTOR must carry out the installation and cabling
of the UPS.
If optional cabinets and accessories are included with the UPS, please refer to those
accompanying manuals for installation and operating instructions.
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.
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 10-20-30-40 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.
A single-phase power outlet (120Vac) should be provided near the UPS for connection of power tools,
test equipment or connectivity devices. This outlet must be grounded.
Positioning of the UPS SG Series 10-20-30-40
Fig. 3.4.1-1 SG Series 10-20-30-40 clearances
The rear panel of the UPS may be mounted flush to a
wall or other structure.
Clearance around the front of the unit should be
sufficient to enable free passage of personnel with the
doors fully open, and to allow sufficient airflow to the
door vents.
Check Section 110-26(A) of the NEC code for specific
requirements.
Recommended minimum clearance between ceiling
and top of the UPS should be 16” (400 mm) for proper
cooling air exhaust.
In case of additional cabinets (external batteries or
input, output transformers) these can be placed on
either side of the cabinet.

protective plate.
Positioning of the UPS cabinet
SG Series 10-20-30-40 is equipped with
wheels for easy placement of the UPS.
To make the UPS movable on wheels, the
bolts on each leg of the cabinet have to be
turned counter-clockwise, until they are
free from the floor and thus the cabinet
supported on wheels.
After having positioned the UPS at its final
location, the cabinet has to be secured by
rotating the bolts on each leg clockwise,
but the wheels must still touch the floor.
Fig. 3.4.1-4 Bolts for the regulation of the cabinet
The UPS cabinet is free
standing and normally does
not require to be bolted to
the floor.
The UPS cabinet can be fixed
however to the floor by
bolting it with the supporting
blocks to the floor.
The supporting blocks can be
used in different positions (0°
- 360°)
These supporting blocks are
part of the shipping package.

In case of parallel system, try to place
the UPS modules in sequence of their
numbers (marked on the packing).
If the units are positioned “side by side”,
the side panels must be mounted on all
units.
3.4.2 Battery location
Batteries require a well-ventilated room with controlled temperature to obtain reliable operation.
The battery can be install 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 location 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.
NOTE !
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 plain floor
Fig. 3.5-2 Installation on raised 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 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 table indicates the heat dissipation at full load at PF = 0.8 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).

3.7 ELECTRICAL WIRING
WARNING !
UPS installation and connection must be performed by QUALIFIED SERVICE
PERSONNEL ONLY.
It is the responsibility of the installation technician to ensure that all local and
national electric codes are adhered to.
3.7.1 Utility input connection
NOTE !
Ensure that the AC and DC external isolators are OFF and locked out to prevent their
inadvertent operation.
Do not apply power to the equipment prior to the commissioning by a qualified
service engineer.
Before any other input connection, connect and check the grounding wire.
The UPS has available input terminations for the Rectifier and Bypass.
The unit may be powered from a common input source or dual input sources if desired.
Dual Input Configuration Rectifier & Bypass (recommended)
The Bypass and Rectifier inputs are to be powered from different Utility supplies (F1 and F2 inputs).
In this case, when the Rectifier Input Fuses are opened, the Bypass and the Manual Bypass are
supplied by the other source.
In this case, REMOVE the interconnection links BR1, BR2 and BR3 on the input
terminals or bus bars.
See Fig. 3.8.4-2 for SG Series 10 & 20 and Fig. 3.8.5-2 for SG Series 30 & 40.
Common input Rectifier & Bypass
The same power source is to be used for both Bypass Supply and Rectifier Input (input F3). Bear in
mind that when the Utility Fuses are opened there is a supply failure to the Rectifier as well as to the
Bypass and Manual Bypass.
In this case, the interconnection links BR1, BR2 and BR3 on the input terminals or
bus bars MUST REMAIN CONNECTED.
See Fig. 3.8.4-2 for SG Series 10 & 20 and Fig. 3.8.5-2 for SG Series 30 & 40.

3.7.2 Input/output over current protection and wire sizing
The cabling of the UPS system has to be sized according to the UPS power rating.
Sizing of circuit breakers, fuses and cables for Input Utility, Output Load and Battery must meet the
requirements of local and national electrical codes.
Before connecting the UPS, verify that the Utility Voltage and Frequency, the Output Load Voltage and
Frequency and Battery Data (cells number, floating voltage, autonomy) are according to the required
specifications.
Output load configuration may be such that one phase may carry a load current at 100% of that phases
maximum current rating while the other two phases run at 0% or any combination in between.
Ensure that the load does not consist of any equipment that may require high starting currents such as
electric motors, laser printers, etc.
This may cause the UPS to occasionally go into Bypass due to overload conditions
To choose the correct input fuses or circuit breaker, consider the available short-circuit current of the
system up-stream.
Choose the correct fuse or breaker using current data shown in the chart and the appropriate NEC
code.
The ratings indicated in the following chart do not consider any line voltage drop.
In case of optional input transformer the input protective devices should be sized to allow the
transformer magnetization inrush current.
Caution when using four-pole circuit breakers as protection.
A potential problem exists for situations with non-linear loads:
The neutral current could be greater than the phase currents.
The three-phase Utility power supply must be symmetrical with respect to ground, due to the existence
of voltage surge protection devices inside the UPS.
NOTE !
If you use ELCB breaker (Earth Limiting Circuit Breaker) to protect the input
connections, consider the high leakage current generated by the noise suppression
capacitors.
If these ELCB breakers are strictly necessary, we suggest using the largest type
suitable for non-linear current and for delayed operations.
To ensure coordination when the UPS is configured for Separate Bypass and Rectifier Inputs, special care
must be taken in choosing the fuse or circuit breaker ratings installed in the output distribution circuits.
Protective devices on the output of the UPS should be coordinated with the Bypass Input circuit
protection.
Due to the relatively low short circuit capability of the UPS inverter, a short circuit in the load will cause
an immediate transfer to Bypass.
The largest fuse or circuit breaker in the output distribution should be rated at no more than 60% of the
rating of the protective device supplying the Bypass line.
If circuit selectivity is required while the load is fed from the inverter (Bypass Utility not available), the
largest fuse or circuit breaker should be rated at no more than 20% of the UPS output current rating.
