Climate Protection
31 Climate Protection
The "Climate Protection" function:
• Supervises and maintains the internal temperature within allowed
ranges for the units in the RBS
• Controls the connection and disconnection of power, at start (or
restart) of the RBS and at extreme internal temperature.
The external temperature range for each RBS type is product-specific.
To get a complete picture of the climate protection system’s capacity,
this document should be read in conjunction with the relevant product
specification.
The Climate Protection of an RBS can be maintained with one or a
combination of the functions described in this chapter.
31.1 Concepts
External Outside the RBS cabinet.
Internal Inside the RBS cabinet.
Normal range Is internal temperature within +5
Cto
+70
C.
Safe range Is internal temperature range which
guarantees full function of the most
temperature sensitive internal equipment.
Normal operation Is internal temperature range which is 5
C
to 10
C within safe range in both high and
low limits.
Specified external Normal Condition range
Are stated in relevant product chapter.
Normal Condition, safe function and non-destruction
Are defined within the context of
Environmental Capability.
User In this chapter, any unit that needs power
from the RBS power system in order to
function.
