IS200EXTBG1AAA机械设备卡件
（Triconex零件号3000793-001是一个包含25个垫圈的套件。）除非已知该区域没有可燃气体浓度，否则不得尝试更换电池、保险丝、I/O模块、主处理器、电源模块、通信模块或I/O接口电缆。连接到主处理器和通信模块的所有通信电缆必须是非易燃的，如附录D“非易燃电路参数”所述。延伸穿过危险区域的通信电缆必须经过非易燃认证。只有经批准在2区危险场所使用的这些组件才能使用：•2770H、HART模拟输入接口模块•2870H、与上述I/O模块兼容的HART模拟输出接口模块v9外部接线板警告•当现场设备处于危险区域时，必须对现场电路采取额外的防爆措施。•当8121型增强型低密度扩展底盘用于2区危险场所时，信号接地和底盘接地必须桥接在一起。•在2区危险场所，2870H型HART模拟输出接口模块必须使用隔离器。176第3章Tricon v9–v10系统欧洲联盟应用的安装和维护规划与安装指南为确保符合欧洲低压和EMC指令，请遵循以下安装指南：•任何含有SMM或SRXM的Tricon机箱必须安装在EMI/RFI屏蔽柜中，并且EMI/RFI滤波必须安装在进入或离开这些机柜的所有电缆上。所有其他机箱都可以安装在标准金属外壳中。•必须根据EN 61010-1《测量、控制和实验室用电气设备的安全要求-第1部分：一般要求》的要求，批准现场电源用于安全超低压（SELV）电路。可接受的EMI/RFI机柜和电缆滤波器包括：•带EMI/RFI屏蔽的Rittal PS或TS机柜（例如，TS8）或同等设备•
(Triconex part number 3000793-001 is a kit containing 25 gaskets.) The replacement of batteries, fuses, I/O Modules, Main Processors, Power Modules, Communications Modules, or I/O Interface cables must not be attempted unless the area is known to be free of ignitable gas concentrations. All communication cabling connected to the Main Processor and Communications modules must be nonincendive as described in Appendix D, Nonincendive Circuit Parameters. Communication cabling that extends through a hazardous area must be certified as being nonincendive. Only these components, which are approved for use in Zone 2 hazardous locations, can be used: • 2770H, HART Analog Input Interface Module • 2870H, HART Analog Output Interface Module v9 External Termination Panels compatible with the above I/O modules WARNING • You must take additional explosion protection measures for field circuits when the field apparatus are in a hazardous area. • When the Model 8121 Enhanced Low Density Expansion Chassis is used in Zone 2 hazardous locations, the signal ground and the chassis ground must be bridged together. • In Zone 2 hazardous locations, an isolator must be used with the Model 2870H HART Analog Output Interface Module. 176 Chapter 3 Installation and Maintenance Planning and Installation Guide for Tricon v9–v10 Systems European Union Applications To ensure compliance with European Low Voltage and EMC Directives, follow these installation guidelines: • Any Tricon chassis containing an SMM or SRXM must be installed in an EMI/RFI shielded cabinet, and EMI/RFI filtering must be installed on all cables entering or leaving those cabinets. All other chassis can be installed in standard metal enclosures. • Field power supplies must be approved for use in safety extra-low-voltage (SELV) circuits according to the requirements of EN 61010-1, Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 1: General requirements. Acceptable EMI/RFI cabinets and cable filters include the following: • Rittal PS or TS cabinet with EMI/RFI shielding (for example, TS8), or equivalent •
