4 Climate Protection
Climate Protection systems have the following functions:
• Supervises and maintains the internal temperature and humidity 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. For a
full understanding 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.
