RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 45 2.6.4.3 Installing Modules WARNING Potentially dangerous voltages may be present on the screw terminals of the module, even though power to the backplane is turned off. Always be careful when handling the removable terminal board of the module and any wires connected to it. ? Be sure the module catalog number matches the intended slot configuration. ? Holding the module firmly, align the module with the correct slot and connector. ? Engage the rear pivot hook(s) of the module (Figure 24) in the notch(es) on the top of the backplane (1). ? Swing the module down (2) until the connector of the module engages the backplane connector, and the release lever(s) on the bottom of the module snaps into place in the bottom module retainer (3). ? Visually inspect the module to be sure it is properly seated. 1 2 3 Figure 24: Installing Module in Backplane 2.6.4.4 Removing Modules PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 46 ? If the module has a removable terminal board, remove it as described later in this section. ? Locate the release lever(s) at the bottom of the module (Figure 25) and firmly press upward (1), toward the module. Wider modules have two release levers that must both be pressed up at the same time. ? While holding the module firmly and fully depressing the release lever(s), pivot the module upward until its connector is out of the backplane (2). ? Lift the module up and away from the backplane to disengage the pivot hook. 1 2 3 Figure 25: Removing Module from Backplane 2.6.4.5 I/O Module Terminal Block Assemblies PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 47 Most PACSystems RX3i I/O modules have removable front terminal block assemblies. Each module of this type has a door label that can be removed, marked up as required for the application, then re-inserted into the retaining grooves, (Figure 28). The front of the label (Figure 26) displays the catalog number of the module and a color band to indicate the module type. It also provides space to record identifying application information about the inputs or outputs wired to the module. The wiring diagram is printed on the reverse side and is visible to the technician (Figure 27) once the door is swung open. The terminal blocks have fully-hinged doors that can be opened to either the left or right to access wiring. REL EASE LEV ER Q1 Q2 Q3 Q4 Q5 Q6 IC694MDL734 Figure 26 Module Door Label Front View Figure 27: Wiring Diagram on Reverse Side of Door Figure 28: Insertion of Door Label following Mark-up for Application 2.6.4.6 I/O Module Connections PACSystems* RX3i System Manual Section 3 GFK-2314T Sept. 2019 Installation 48 For most RX3i I/O modules, connections are made to the removable terminal board of the module. Specific wiring information for each module is printed on the door insert and also shown in the module description in this manual. This section describes the 20-Connector removable terminal block (Figure 29), which is used by most RX3i I/O modules. Higher-density modules use other connection methods. Refer to Chapter 17 for details concerning the following: ? 36-pin removable terminal blocks used for most higher-density modules. ? Connections to I/O modules that have two 20- Connector connectors on the front of the module. ? Terminal Board Quick Connect (TBQC) system that allows users to land the field wiring on interposing terminal strips and complete the connection to the I/O module using pre-fabricated interconnect cables. Screw terminals on a 20-Connector terminal block accept from two AWG #22 (0.36 mm2 ) to two AWG #16 (1.3 mm2 ), or one AWG #14 (2.1 mm2 ) copper 90°C (194°F) wire(s). Each terminal can accept solid or stranded wires, but the wires into any given terminal should be the same type (both solid or both stranded) to ensure a good connection. Wires are routed to and from the terminals out of the bottom of the terminal board cavity. The suggested torque for the I/O terminal board connection screws is from 1.1 to1.3 Nm (9.6 to 11.5 in-lb). After the wiring is completed, wires should be bundled and fastened at the bottom of the terminal block, as shown in Figure 29.
