6 Section 2 Product Overview 2.1 Available Termination Panels Available CL6340-Series termination panels are: 2 Type CL6341 Analog Input Termination Panel Type CL6342 Analog/Smart Device Output Termination Panel (HART Compatible) Type CL6343 Discrete Input/Output Termination Panel Type CL6344 Pulse Count Termination Panel Type CL6345 Smart Device Input Termination Panel (HART Compatible) Note... System designers must follow certain requirements when designing an intrinsic safety system using CL6340-Series termination panels. Refer to the vendor s instruction manual, MTL4000 Series Isolating IS interface units, INM4000 and Section 3 of this manual for an overview of these requirements. Table A-3 in this manual provides a cross reference between the PROVOX type number and the MTL model number. 2.2 Available Intrinsic Safety Barriers CL6350-Series Intrinsic Safety (IS) Barriers plug into CL6340-Series termination panels and provide field voltage and current limitations required by an intrinsically safe I/O system. Available barriers are: Type CL6351 IS High-Level Analog Input Isolating Barrier (HART compatible) [4-20 ma] Type CL6352 IS Millivolt Input Isolating Barrier Type CL6353 IS RTD Input Isolating Barrier Type CL6354 IS Thermocouple Input Isolating Barrier Type CL6355 IS Analog Output Isolating Barrier This barrier is available in a 4 to 20 ma version for analog output signals and a HART-compatible version for smart device output signals. Type CL6356 IS Discrete Input Isolating Barrier Type CL6357 IS Discrete Output Isolating Barrier

Product Overview Section 2 7 Type CL6358 IS Discrete Pulse Count Input Isolating Barrier Refer to the vendor s instruction manual, MTL4000 Series Isolating IS interface units, INM4000 and Appendix A of this manual for descriptions and specifications of CL6350-Series barriers. 2.3 Determining the Quantity of Barriers and Termination Panels for Your Application 2 The quantity and type of barriers, and termination panels, used for an application depend on the field signals and backup strategy. CL6350-Series barriers for the following signals are available: Analog Input (AI) Analog Output (AO) Smart Device Input (HART compatible) Smart Device Output (HART compatible) Discrete Input (DI) Discrete Output (DO) Pulse Count Input (PCI) Types of backup strategies you may choose are: Simplex (No backup) 1 for 1 Redundancy 1 for N Redundancy First, determine the number of barriers your system requires. Each signal that you want to connect to the PROVOX system from the hazardous area must connect to a barrier. All CL6350-Series barriers, except Type CL6356, accept one signal from a hazardous area. The Type CL6356 IS discrete input isolating barrier accepts two input signals. Therefore, you need a barrier for each type of signal except a discrete input signal, for which you need one barrier for every two signals. Secondly, determine the number of termination panels required. Each termination panel can accept as many as 16 barriers carrying the same kind of signals, except for the Discrete Input termination panel, which can accept 32 signals (16 barriers with two inputs each.) You cannot mix major barrier types (AI, AO, DI, DO, PCI, Smart Input, and Smart Output) on a termination panel. For example, you cannot put

8 Section 2 Product Overview 2 analog input barriers on the same panel as analog output barriers. Also, you cannot mix analog barriers and smart device barriers on the same panel. However, you can put the Type CL6353 RTD and Type CL6354 Thermocouple IS Input Isolating Barriers on the same panel because they are both analog input barriers, using the same analog I/O card. Next, determine the number of I/O cards needed. To relate the number of termination panels and barriers to the number of I/O cards, consider the number and type of channels an I/O card can have. For example, an Analog I/O card can have as many as 16 analog input channels or as many as 8 analog output channels; a Discrete I/O card can have as many as 16 discrete inputs, 16 discrete outputs, or 8 pulse count input channels. Do not mix input and output signals on the same card. The signals must be all input, or all output, or all pulse count input. Table 2-1 shows the maximum number of input or output channels supported by I/O cards. Knowing the number of channels you wish to use, up to the maximum, you can calculate the number and type of I/O cards you need. Table 2-1. I/O Card Type Maximum Number of Channels Supported by I/O Cards Maximum Number of Input Channels Maximum Number of Output Channels Type CL6721 Discrete I/O 16 (1) 16 8 Type CL6821 Analog I/O 16 8 Type CL6824 Analog Input 16 Type CL6825 Smart Input 16 Type CL6826 Smart Output 8 1. 16 input channels permits 32 input signals, two input signals per input barrier. Maximum Number of Pulse Count Input Channels 2.4 Physical and Electrical Pre-Installation For detailed system planning information before installing the intrinsic safety system, consult the documents listed in Table 2-2. Table 2-2. System Planning Documents INM4000 MTL4000 Series Isolating IS interface units (vendor s manual) PN1:002 Planning the Installation PN1:003 AC and DC Power and Ground Wiring PN1:004 Signal Wiring and Data Highway Guidelines PN1:006 Environmental Conditions for Instrumentation Systems PN1:007 Lightning Protection Guidelines for Instrumentation Systems PN4.4:CP7043 Installing Type CP7043 System Cabinets

Installation Section 3 9 Figure 3-Table 3 3 3 Installation 3 Before a system is installed, both physical planning and electrical planning is required. This section provides information for both. The manuals listed in Table 2-2 describe other pre-installation physical and electrical planning. 3.1 Special Considerations Appropriate precautions must be taken when using control instrumentation in areas where explosive gases or vapors are present. Precautions include special handling and special wiring. Simply installing CL6340-Series termination panels and CL6350-Series barriers does not necessarily provide a certifiable intrinsically safe system. A certifiable system is a matter of design. To be certifiable, a system must be designed and installed according to guidelines relevant to the country of installation and provided by the locally approved certifying authority. Regulations governing intrinsic safety applications may preclude, or make difficult, the mounting of CL6340-Series and CL6350-Series products in cabinets which contain other equipment, such as Control I/O termination panels and MUX I/O files. Consult your certification authority if combined mounting is essential. Also see the vendor s instruction manual, MTL4000 Series Isolating IS interface units, INM4000, especially sections 3, 5, and 9 which describe various precautions and warnings to heed prior to and during installation. 3.2 Planning the Physical Installation The following subsections describe how to install the physical elements of an intrinsically safe system. 3.2.1 I/O Cards and Card File The I/O cards can be installed in any one of the 14 l/o card slots in the Type CP6701 Control I/O Card File (Figure 3-1). An l/o card can be configured either as simplex, or for a redundant configuration, as the

10 Section 3 Installation primary card or backup card. One backup can provide redundancy for a maximum of eight primary cards (1 for 8). Primary Power/Communication Card Secondary Power/Communication Card Backplane 3 Space for 14 I/O Cards Power Connection Card Figure 3-1. Type CP6701 Card File Arrangement X00751 A The three left card slots of the l/o card file are reserved for the power connection card, the primary power/communication card, and the secondary power/communication card. Refer to installation manual, Installing the Control I/O Subsystem, PN4.4:CP6701, for detailed information regarding the installation of an l/o card file. Note... See installation manual, Installing Type CP7043 System Cabinets, PN4.4:CP7043, for termination panel location guidelines in relation to the I/O card file, SR90 controller, door-mounted fans, and other PROVOX equipment. 3.2.2 Termination Panel Installation Termination panels mount on standard 19-inch EIA rails. The panels require no operator access and should be mounted in cabinets or equipment rooms with access for maintenance personnel only. The Type CP7043 System Cabinet is designed specifically to house these products. For more information about the cabinet, refer to product bulletin, BU4.4:CP7043. Figure 3-2 shows the dimensions of a CL6340-Series termination panel with barriers installed.

12 Section 3 Installation 3.2.4 Termination Cables Termination cables connect the I/O cards to CL6340-Series termination panels. The cables can be a maximum of 200 feet (60 m) long. For details on available cables and approved lengths, and a table which lists helpful cable installation tools, refer to Appendix B of this manual. 3 Note... Compliance with electromagnetic compatibility legislation may be compromised through the use of cables other than those supplied with the product. You must make sure that cable ducting does not become too full. With a maximum of ten panels possible on one side of a Type CP7043 cabinet, and a maximum of four cables for each term panel, there can be potentially 40 cables in the ducting; however, the number of cables should not exceed 30. Note... The number of cables in the ducting of the Type CP7043 System Cabinet should not exceed 30. Also, for a Type CL6741, Type CL6841, or Type CL6842 cable interface panel, at least one rack-unit of space between the top of the panel and the next panel above it must be left open. Cables are routed out of the top of the interface panels and require the space to make a proper radius bend. 3.2.4.1 Cabling for Simplex I/O Cards The number of cables and connections you require depends on the type of I/O card and the type of redundancy strategy you are using. For example, assume you have a termination panel that contains 16 Type CL6355 IS Analog Output Isolating Barriers which you are connecting to two Analog cards (with 8 channels each). To implement this example in a simplex system, you need two cables: one to connect each analog I/O card to the termination panel. (The cables for connecting the analog cards to the termination panel are supplied with the termination panel).

Installation Section 3 13 Figure 3-4 shows the connections between the two analog output cards and the termination panel in a simplex system.

Installation Section 3 21 3.2.4.3 Cabling 1 for N Configurations Cabling for 1 for N redundancy (where N = 2 to 8 primary I/O cards) requires a Cable Interface Panel. The panel allows 1 backup I/O card to provide redundancy for two to eight primary I/O cards. The Cable Interface Panel is not required 1 for 1 redundancy. The cable length between the primary I/O card and the termination panel must not exceed 200 feet (60m). Also, the overall length of the cables connecting the I/O card, the Cable Interface Panel, and the termination panel must not exceed 200 feet (60m). 3 All termination panels and cable interface panels have either two or three terminals labeled SHLD. One SHLD terminal on each panel must be connected to the cabinet ground. Note... Cabinet mounting rails are grounded so that a short grounding strap attached to the rail and a mounting bolt or grounding stud on the back plate will provide adequate grounding. The following examples show some multiple card and termination panel combinations. Not every possible redundancy combination is shown. Use these examples to help you determine the correct wiring for your redundancy strategy and card application.

You should attach the spare connector to the end of the termination cable according to the instructions provided with the connector. Refer to Table 3-1 for D-shell connector pin assignments (37-pin and 25-pin). Note... If you find it necessary to route the cable through a small area, cut the cable near the connector that you will attach to the termination panel. An extra connector is provided with cables of 50, 100, or 200 feet (15, 30, or 60m) for this purpose.

28 Section 3 Installation 3.3 Planning the Electrical Installation Each element in the installation has specific electrical requirements that must be considered. The following subsections provide planning information and electrical requirements for the elements. 3 The supplied wiring kit includes pre-terminated wires of the correct gauge and length to make the required connections when the panels are mounted in a Type CP7043 System Cabinet. 3.3.1 Termination Panel Power Termination panels are supplied with nominal 24 Vdc power. Each panel is protected by a fuse. Screw terminals on the panels can accommodate two 14 AWG wires or a single 22 AWG wire. Four screw terminals provide connections for primary and secondary +24 Vdc and Power Supply Common. The primary and secondary power terminals are labeled PRI +24 V and SEC +24 Vdc, respectively. Two redundant Power Supply Common terminals are labeled PSC. Refer to Figure 2-1 to see the location of the power connector on the termination panel. To connect power to the termination panels: Step 1: Step 2: Connect the positive wire from your 24Vdc supply to the terminal labeled PRI +24 V. If you have a secondary power supply, connect the positive line to the terminal labeled SEC +24 Vdc. Note... If redundant power supplies are not used, place a jumper between the terminals labeled PRI +24V and SEC +24V. Step 3: Connect the screw terminal labeled PSC to the return, or negative, line of the 24Vdc power supply. Both simplex and redundant termination panels have two screws labeled SHLD that provide shield grounding for the termination cables. Use the short black wire in the wiring kit to connect one of these terminals to the stud on the metal chassis. For more information about grounding, refer to subsection 3.3.2.

Installation Section 3 29 3.3.2 Shield Grounding A ground bar kit containing grounding terminals is optional and available where field cable shield grounding is required at the termination panel. For detailed information on grounding, refer to the following documentation: AC and DC Power and Ground Wiring, PN1:003 Signal Wiring and Highway System Guidelines, PN1:004 Installing Type CP7010 Cabinets, PN4.4:CP7010 Installing Type CP7043 Cabinets, PN4.4:CP7043 3 Warning... If your system uses shield grounding, ground shields at one end only. The other ends must be carefully insulated to prevent possible sparks or possible current flow between different potential ground points. 3.3.3 DC Grounding The Power Supply Common (PSC) circuitry must be grounded through a local ground bus (LGB) or a master ground bus (MGB) to the designated system earth ground. For specific DC grounding information, refer to the documentation listed in subsection 3.3.2. 3.3.4 Connecting Field Wiring to Barriers Hazardous area field wiring is connected to the BLUE terminal blocks that plug into the front of the barrier. Either connect the wires using the screws on the terminal block (maximum gauge 12 AWG) or by using an optional push-in and crimp type block. Figure 3-19 shows the barrier and terminal connections. For detailed information about barrier field wiring connections, refer to the specifications for the individual barriers in Appendix A and the vendor s instruction manual, MTL4000 Series Isolating IS interface units.
