Figure 19: Effect on Load Rating, Vertical Mounting Power supply load ratings with the backplane mounted horizontally are: ▪ Temperature at 25°C (77°F) – full load ▪ Temperature at 60°C (140°F) – 50% of full load Figure 20: Effect on Load Rating, Horizontal Mounting PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 34 2.6.3 Mounting a Backplane in a 19-Inch Rack The IC693ACC308 Front Mount Adapter Bracket (Figure 21) can be used to mount a 10-Slot Expansion Backplane, IC694CHS392, to the front face of a 19-inch rack. Install the adapter bracket by inserting the tabs at the top and bottom of the adapter bracket into the corresponding slots at the top and bottom of the plastic backplane cover. It is not necessary to remove the cover to install the bracket. With the bracket in place, insert and tighten the two screws (included with the bracket) through the back of the backplane holes into the threaded holes in the bracket. Insert two screws (one at top; one at bottom) from the back of the baseplate through the baseplate mounting holes into tapped holes in the bracket. Tighten both screws to secure the bracket to the baseplate.

This bracket cannot be used with a Universal Backplane. An Expansion Backplane mounts on the rear panel of this adapter bracket using four 8-32 (4mm) screws, nuts, lock washers, and flat washers. The Adapter Bracket bolts through its four slotted holes to the face of the 19” rack using applicable hardware (lock washers recommended). 4.06mm (0.160 inch) dia. x 4 21.4mm (0.842 inch) 8.8mm (0.346 inch) inside 428mm (16.850 inches) 460.3mm (18.122 inches) 90mm (3.540 inches) 7.1mm (0.280 inch) 34.7mm (1.368 inch) 11.2mm (0.439 inch) 41.4mm (1.630 inches) 101.6mm (4.00 inches) Figure 23: IC693ACC313 Recessed Mount Adapter Bracket 2.6.3.1 Grounding Rack-Mounted Expansion Backplanes If an Expansion Backplane is mounted in a 19-inch rack using an Adapter bracket, the rack must be properly grounded as described in the section, System Grounding Procedures. In addition, the backplane should be grounded according to the guidelines in the section, Backplane Safety Grounding, using a separate ground wire from the PLC backplane. ▪ For a Recessed Mount Adapter Bracket (IC693ACC313), the ground wire can be installed with the ground attached to the Recessed Mount Adapter Bracket. An additional ground wire should be installed that connects the Adapter Bracket to a solid chassis ground. ▪ For a Surface Mount Adapter Bracket (IC693ACC308), the ground wire should be run from the backplane to a solid chassis ground on the rack. PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 36 2.6.4 Modules 2.6.4.1 Hot Insertion and Removal In general, modules in a Universal Backplane (IC695CHS007, CHS012 or CHS016) can be installed or removed while power is applied to the system. This includes backplane power and field power supplied to the module. However, no CPU modules fall into this category. The following table lists the I/O modules that do not support this feature or have not yet been verified to support this feature. Note: For products that support hot insertion, the module must be properly seated on the carrier with the latch engaged and all pins connected within 2 seconds. For removal, the module must be completely disengaged from the carrier within 2 seconds. It is important that the module not remain partially inserted during the insertion or removal process. There must be at a minimum of two seconds between the removal and insertion of modules. Note: A CPU module cannot be installed or removed from a Universal Backplane while power is applied to system. System power must be removed before installing or removing the CPU. The following modules support hot insertion and removal, with restrictions as noted: Catalog Number Hot-Swap Compatible Notes / Restrictions on Hot Swap Capability IC693ACC300 Yes IC694ACC300 Yes IC695ALG106 Yes IC695ALG112 Yes IC693ALG222 Yes - Revision FA & later Revision E & earlier do not support hot swap.
