STORING THE CPS AND THE BATTERY BOX
The storage room must respect the following conditions:
PREPARING FOR INSTALLATION
PRELIMINARY INFORMATION
Max. relative humidity during operation
Max. height of installation
1000 m at rated power
(-1% Power for every 100 m above 1000 m)
max 4000 m
Power dissipated at rated resistive load
(pf=0.9) and with battery as buffer *

Flow rate of fans for removing heat from
installation room **
Current leak to earth ***
* 3.97 B.T.U./h = 1 kcal/h
** The following formula can be used to calculate the fan capacity: Q [mc/h] = 3.1 x P
diss
[kcal/h] / (t
a
- t
e
) [°C]
P
diss
is the dissipated power of all the installed apparatus at the installation premises expressed in kcal/h.
ta= environmental temperature, te= external temperature. To account for leaks, increase the value obtained by 10%.
The table shows an example of the fan capacity with (t
a
- t
e
)=5°C and with nominal resistive load (pf=0.9).
(N.B.: The formula applies if ta>te; otherwise an air conditioner should be installed).
*** The dispersion current of the load is added to the dispersion current of the CPS on the earth protection conductor.
