4.5 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.
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.
20" (500mm) of air clearance from the top must be left free of any object for a sufficient exhausted
air exchange, proper cooling, service access and safety.
Air filtering systems could be required when the UPS operates in a dirty environment.
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.
Contact your ABB Service Center for appropriate solutions.
