VENTILATION AND COOLING

Fig. 3.5-1 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.
UPS produces maximum heat dissipation while operating in Double Conversion Mode, design ventilation
or cooling system to meet heat dissipation for this operating mode. Install suitable ventilation or cooling
system to extract the heat from the UPS room.
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.
The below table indicates the heat dissipation at full load at PF = 0.9 lag. and charged battery, up to
3,280 ft (1,000 m) altitude, for cooling air 77°F (25°C) to 86°F (30°C).
