RX3i Universal Backplane Installation

The RX3i system and its components are considered open equipment (having live electrical parts that may be

accessible to users) and must be installed in a protective enclosure or incorporated into other assemblies

manufactured to provide safety.  As a minimum, the enclosure or assemblies must provide protection equivalent to a

NEMA/UL Type 1 enclosure or an IP20 rating (IEC60529). The enclosure must be able to adequately dissipate the

heat generated by all of the components mounted inside so that no components overheat.  A minimum space of at

least 102mm (4 inches) as shown below is required on all sides of the RX3i backplane for cooling.  Additional space

may be required, depending on the amount of heat generated by the equipment during operation. Please refer to the

PACSystems RX3i System Manual, GFK-2314. for information about enclosures and heat dissipation.

Backplane Orientation

Backplanes must be mounted horizontally to meet product

performance and reliability specifications by providing

adequate airflow around the modules.  Other mounting

orientations may affect system performance and/or reliability

and are therefore not recommended.
