the following limit values:
Ambient temperature
•
Maximum
•
Maximum 24 hour average
•
Minimum
•
Site altitude
-
≤1000 m above sea level
•
Ambient air
The ambient air is not to be significantly
contaminated by dust, smoke, corrosive or
flammable gases, or salt.
1.3.2 Special operating conditions
Special operating conditions are to be agreed by
the manufacturer and operator. The manufacturer
is to be consulted in advance about each special
operating condition:
•
Site altitude above 1000 m
-
The manufacturer's specifications are to be
observed
•
Increased ambient temperature
-
The current carrying capacity is reduced
-
Additional cooling facilities for heat dissipation
are to be provided
•
Climate
-
In areas with high humidity or major rapid
temperature changes, condensation inside
the low voltage compartment needs to be
prevented (e.g. by installing electric heaters
in that compartment)
