NSTALLATION
When choosing the place of installation of the UPS and the Battery Box, observe the following:
avoid dusty environments
ƒ
check that the floor is level and able to support the weight of the UPS and the Battery Box
ƒ
avoid environments which are too restricted as these could hinder normal maintenance operations
ƒ
the relative humidity in the environment must not exceed 90%, without condensation
ƒ
check that the ambient temperature, while the UPS is running, remains between 0 and 40°C
ƒ
The UPS is able to operate at an ambient temperature of between 0 and 40°C. The recommended
operating temperature for the UPS and the batteries is between 20 and 25°C. The battery
manufacturers point out that, if the operating life of the batteries is 5 years on average with an
operating temperature of 20°C, moving the operating temperature up to 30°C halves their lifespan.
avoid positioning in places which are exposed to direct sunlight or hot air
ƒ
In order to ensure the temperature in the place of installation remains within the aforementioned range, it is necessary to
arrange a heat dispersion system (the value of the kW / kcal/h / BTU/h* dissipated by the UPS is shown in the "Technical
data" section"). The methods used are the following:
natural ventilation**
ƒ
forced ventilation, recommended if the external temperature is lower (e.g. 20°C) than the temperature at which
ƒ
the UPS or Battery Box is to operate (e.g. 25°C)
air conditioning system, recommended if the external temperature is higher (e.g. 30°C) than the temperature set
ƒ
for operation of the UPS or Battery Box (e.g. 25°C)
*
3.97 BTU./h = 1 kcal/h
** To calculate the air flow rate, it is possible to use the following formula: Q [m³/h] = 3.1 x P diss [kcal/h] / (a t - e t ) [°C]
P diss is the dissipated power expressed kcal/h in the place of installation by all the installed equipment.
at= ambient temperature, et=external temperature. In order to take leaks into consideration, it is necessary to increase the
resulting value by 10%.
The table shows a sample flow rate where (a t - e t ) =5°C and the rated resistive load (pf=0.9).
(N.B. The formula applies if at>et; otherwise installation requires an air conditioner).
P
OSITIONING THE
When positioning the UPS, it is necessary to bear the following in mind:
there must be enough free space in front of the equipment to allow it to be switched on/off and any maintenance
ƒ
operations to be carried out ( t 1.65 m )
the back of the UPS must be positioned at least 50 cm away from the wall in order to ensure a correct flow of
ƒ
the air coming out of the ventilation fans and to allow access to the "BC/BYP COMPARTMENT"
the top must be at least 50 cm away from the ceiling in order to allow maintenance operations
ƒ
no objects must be rested on the top
ƒ
