§ Route sensitive input wires away from electrically-noisy wires such as discrete output and AC wiring. This can be facilitated by grouping I/O modules to keep output modules separated from sensitive input modules. § Clearance space of 10 cm (4 in) on all four sides of each RX3i backplane for ventilation/cooling is required. § RX3i backplanes are designed to be mounted horizontally due to thermal considerations.

At a minimum, the enclosure or assemblies shall provide a degree of protection against solid objects up to 12mm (e.g. fingers). This equates to a NEMA/UL Type 1 enclosure or an IP20 rating (IEC60529) providing at least a pollution degree 2 environment. When an RX3i system is installed into an area designated as a Hazardous Area, then the enclosure must be one that is only accessible by use of a tool. Refer to Appendix A for reference to specific product certifications, types of Hazardous Area approvals, Hazardous Area warnings, and additional enclosure requirements with respect to ATEX. The enclosure must be able to adequately dissipate the heat generated by all of the components mounted inside so that no components overheat. Heat dissipation is also a factor in determining the need for enclosure cooling options such as fans and air conditioning. A minimum space of at least 102 mm (4 in) 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, or on other PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 22 requirements such as minimum bend radius for system cabling. Appendix B explains how to calculate heat dissipation for RX3i modules and field devices in an enclosure. 2.3.1 RX3i Universal Backplane Dimensions and Spacing * Allowance for cooling Universal Backplane front view Side dimension is for standard modules with doors closed. Side dimension does not include extra depth required for cables and connectors. Modules with Extended High-Density Terminal Blocks (such as Terminal Block IC694TBB132) are approximately ?-inch (13mm) deeper overall. Figure 9: RX3i Universal Backplane Dimensions and Spacing PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 23 The mounting holes for the 12-slot RX3i Universal Backplane match the 10-slot Series 90-30 Backplane exactly, for easy upgrades. Backplanes must be mounted horizontally, as represented above, to meet product performance and reliability specifications by providing adequate airflow around the modules. Other mounting orientations may affect system performance, reliability and agency approvals, and are therefore not recommended.
