VENTILATION AND COOLING
Fig. 4.5-1 Installation on plain floor
The heat produced by the UPS is transferred to the environment by its ventilation.
Cooling air enters the cabinets through the air inlet (grids) located at the bottom and exhausted through
the outlet on the roof.
A suitable ventilation or cooling system must be installed to extract the heat from the UPS room.
NOTE !
Insufficient distances on both sides of the UPS could increase the temperature
inside the UPS.
Do not put any object on the top of the cabinet: it might obstruct the air flow.
If the UPS is placed on a raised floor, the airflow for UPS cooling should enter from underneath the UPS,
through the appropriate aperture on the raised floor.
Air filtration systems could be required when the UPS operates in a dirty environment.
Contact your Dealer or the nearest Service Centre 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
1000 m (3280 ft) altitude, for cooling air 25°C (77°F) to 30°C (86°F).
