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.
