2.2.2 Fluoro UPS Option
Illustration 3-1:
The Fluoro UPS batteries require a cooling system to keep ambient temperature
below 25 ºC (77 ºF).
The heat produced by the UPS is transferred to the environment by its ventilation. Cooling
air enters the cabinets through the air inlet (grids) located at the bottom and exhausted
through the outlet on the roof. A suitable ventilation or cooling system must be installed to
extract the heat from the UPS room.
Make sure there is a ventilation air flow, preferably ensured by natural air flow,
otherwise by enforced ventilation, so that hydrogen concentration is below 1%
(according to Standard IEC 62040-1-2).
Do not put anything on the top of the cabinet.
If the UPS is placed on a raised floor, the airflow for UPS cooling should enter from
underneath the UPS, through the appropriate aperture on the raised floor.
If the UPS runs in a dusty environment, we recommend strongly to install filters on the air
inlet of the UPS room. In this case it should be considered that these filters can cause
reduced speed at the air inlet.
The size of the air inlet has therefore to be dimensioned accordingly.
Contact your Local Distributor or one of the Service Centre, which will help you to find
valuable solutions.
The tables below indicate the heat dissipation at full load at PF = 0.8 lag. and charged
battery, up to 1000 m (3280 ft) altitude, for cooling air 25 C (77 F) to 30 C (86 F).

VFI (Voltage Frequency Independent) UPS system where the load is continously
supplied by the inverter through the rectifier.
