to 0 V) or the signal initiates actions on a high-to-low transition.
•
The use of a '\' (backslash) prefix to a signal name indicates an active low

Product Properties
Certification
The product or products described in this technical manual cannot be operated
by themselves. They are components for integration into operational systems or
add-ons to such systems. The products have been designed to meet relevant
regulatory standards like FCC and CE. As mandated by these standards
conformance to these standards can only be certified for complete operational
systems. This has to be done by the end-user or by the systems integrator in
their operational systems. GE Intelligent Platforms have tested some products
in their own systems. Upon request information is available which products
have been tested and about the specific environment under which GE
Intelligent Platforms has tested these components.
Altitude
Altitude, air pressure and ambient temperature influence the thermal operation
of the components described in this manual. They have been developed and
tested at about 500 m (1650 ft.) above sea level at a typical ambient
temperature of 20 °C (68 °F). Because of only marginal variations within a
limited range of altitudes these products operate as specified within altitudes
from sea level to 1000 m (3300 ft.). This is with reference to temperature
ranges of air-cooled versions. GE Intelligent Platforms can assist the user of
these components in planning operation outside this altitude range upon
request.
Options
This manual describes the basic product plus all options. Your product may not
have all options implemented. Please verify with your purchase contract which
