3.1 Positioning constraints
The UPS must be positioned respecting the following conditions:
- temperature and humidity must be within permitted limits;
- fire regulations must be respected;
- the wiring must be simply made;
- front accessibility must be available for assistance or periodic servicing;
- the cooling flow of air must be guaranteed;
- the air conditioning system must be adequately scaled;
- conductive/corrosive/explosive dust and/or gas must be absent;
- the premises must be free of vibration;
- the rear and side space must be enough to guarantee an adequate circulation of air for cooling. Position the UPS at a
distance of at least 20 cm from the wall so that all the ventilation openings are free from any obstruction.
- Do not expose the equipment to the direct sunlight Do not install the equipment nearby devices that emit heat, such
as radiators or ovens.
To safeguard the batteries as well as possible it is necessary to bear in mind that their average lifetime is strongly influ-
enced by the operating room temperature.
Position the UPS in an environment with a temperature range between +20°C (+68°F) and +25°C (+77°F) to guarantee the
optimum life of the batteries

connections are made on the basis of local installation standards.
After removing the UPS from the packaging and positioning it in its definitive place, the skilled technician can begin to
make the electric connections.
CAUTION
The choice of cable type and their cross sections depending on the current they carry and their installations must
be made as indicated by the installation standards in force and it is a responsibility of the skilled technician.
