5: RX3i System using One Universal Backplane and One Expansion Backplane 1.5.2 Using Multiple Expansion and Remote Backplanes The next two example systems are similar to each other except for the distance between the backplanes. The example on the left includes two RX3i Expansion Backplanes and a Series 90-30 Expansion Backplane. The Expansion Backplanes can be any combination of RX3i (IC694) and Series 90-30 (IC693) Expansion Backplanes. I/O modules in the system can be any combination of RX3i and Series 90-30 modules. In the example on the right, two of the backplanes must be installed beyond the 15 m (50-ft) limit of an Expansion system. Two Series 90-30 Remote Backplanes are used in those locations. All other features of the two example systems are the same, including their I/O modules.

If any part of the system is damaged, notify the carrier immediately. The damaged shipping container should be saved as evidence for inspection by the carrier. As the consignee, it is your responsibility to register a claim with the carrier for damage incurred during shipment. However, we will fully cooperate with you, should such action be necessary. After unpacking the RX3i equipment, record all serial numbers. Serial numbers are required if you should need to contact Customer Care during the warranty period. All shipping containers and all packing material should be saved should it be necessary to transport or ship any part of the system. Verify that all components of the system have been received and that they agree with your order. If the system received does not agree with your order, contact Customer Care. If you need technical help, contact Technical Support. For phone numbers and email addresses, refer to Contact Information. PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 20 2.2 System Layout Guidelines A good layout helps minimize the chance of electrical shock to personnel working on the system. It lets maintenance technicians easily access the unit to make measurements, load software, check indicator lights, remove and replace modules, etc. It also makes it easier to trace wiring and locate components while troubleshooting. In addition, proper system layout promotes good heat dissipation and helps eliminate electrical noise from the system. Excess heat and noise are two major causes of electronic component failure. § Locate RX3i equipment away from other components that generate a lot of heat, such as transformers, power supplies, or power resistors. § Locate RX3i equipment away from components that generate electrical noise such as relays and contacts. § Locate RX3i equipment away from high-voltage components and wiring, such as circuit breakers and fusible disconnects, transformers, and motor wiring. § Locate equipment at a convenient level that allows technicians reasonable access for maintaining the system.
