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.
