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.
