5.3 Notes
5.3.1 Climatic and mechanical environmental conditions in operation
Note
The following information refers to the electrical section of the HLA.
IEC 68-2-1, IEC 68-2-2, IEC 68-2-3
If the specified values cannot be maintained, then a heat exchanger or air con-
ditioner must be provided.
Table 5-6 Climatic ambient conditions
Temperature range Lower limit temperature 0°C
Upper limit temperature +55°C
1)
Dew-point temperature td
and relative air humidity U
Annual average U = 75%, td = 17°C
On 30 days (24 hours) in
year (days distributed over
the annual period)
U = 95%, td = 24°C
On other days (<24 hours)
(observing the yearly aver-
age)
U = 85%, td = 20°C
Condensation not permissible
Temperature rate of
change
Within one hour 10 K
Within three minutes 1 K
Atmospheric pressure When operated at an alti-
tude of 1500m above mean
sea level. For greater alti-
tudes, the upper limit tem-
perature must be reduced
by 3.5°C/500m.
86 kPa to 108 kPa
