1.4.4 Climate Control Requirements
The RBS 3202 is designed for normal operation in climate control class 3.1 of
ETS 300 019–1–3 in accordance with IEC/EN 60 721-3-3.
Climate control must be configured to site power consumption and site heat
generation.
The RBS 3202 can function under the following operating conditons:
• Normal operating conditions
Normal operating conditions are defined as environmental conditions
where all units function as specified.
• Exceptional (safe) operating conditions
Exceptional operating conditions are defined as environmental stress
above the limits for normal operation where all units continue to function
under stress, but performance or capacity may be reduced. Reduction
of performance or capacity must be documented. When environmental
stress returns to normal conditions, function as specified is automatically
achieved. Exceptional operating conditions are normally tested with one
parameter at a time exceeding the limits for normal operation. Exceptional
operating conditions are considered to be a period of not more than 72
consecutive hours, and a total of not more than 15 days in one year.
• Non-destructive operating conditions
Non-destructive operating conditions are defined as environmental stress
above the limits for safe function during which no function is guaranteed
and performance may be degraded in an unspecified manner. When
environmental stress returns to normal conditions, no manual intervention
(on the site) is required to restore full performance of the RBS 3202. If
remote control action must be performed to restore specified performance,
the event must be documented. Non-destruction operating conditions are
normally tested with one parameter at a time exceeding the limits for
normal operation. Non-destruction operating conditions are considered to
be a period of not more than 96 consecutive hours, and a total of not more
than 5.5 days in a 3 years period.
Normal, exceptional, and non-destructive operating conditions for the RBS
3202 are shown in table 3.
