ATTENTION
l (1) Operating Limits define the range of operating conditions within which the
system is designed to operate. Performance characteristics are defined when
operating in this state. Refer to ANSA/ISA D 51.1 for more information.
o Transportation and Storage Limits define the range of conditions to which
the system may be subjected without permanent damage to the
equipment. Performance is not guaranteed in this state. Refer to ANSA/ISA
D 51.1 for more information.
l (2) This rating applies to the internal ambient temperature of the enclosure with the
doors closed.
l (3) The maximum relative humidity spec applies up to 40°C. Above 40°C, the RH spec
is de-rated to 55% to maintain constant moisture content.
l (4) Measured with the field strength meter near the surface of the electronics with
doors open.
l (5) Applied to items those are likely to be in contact with discharge sources (For
example, human body) during typical maintenance actions.
l (6) 10 Hz is approximate – exact crossover frequency is determined by the
intersection of the displacement and acceleration.
l (7) Composite Transportation Test Curve--encompassing maximum Random
Vibration power spectral density values associated with ground, air, and sea
transportation environments.
The rail-mounted UIO is not designed to meet the Marine Application requirement.
