• 保持屏蔽的连续性，并确保屏蔽导线不断裂。允许容纳连接的最小数量的非屏蔽电线。如果怀疑存在潜在接地回路，则在两端终止屏蔽，在一端使用电容耦合。•如果铁氧体或线路滤波器安装在进出机柜的信号或电缆上，则必须尽可能靠近机柜出口点。电缆布线必须尽量减少滤波信号和未滤波信号之间的耦合。机柜中未经过滤的电线长度必须尽可能减少到最大限度。警告：对于使用交流逆变器的不间断电源（UPS）的应用，Triconex建议您在每个交流电源的机柜电源入口点安装交流线路滤波器。根据机柜中最坏的交流负载选择滤波器的尺寸，并根据第170页的Tricon Field、Power和Ground Wiring指南安装滤波器。合适的滤波器包括Schaffner FN 350系列或Corcom SK系列。警告：从Tricon机箱背板上卸下ELCO连接器之前，请务必关闭现场电源。现场电源打开时可能会出现危险电压，并可能损坏Tricon背板和终端面板。172第3章Tricon v9–v10系统安装和维护规划与安装指南应用程序特定安装指南以下指南适用于在应用程序特定位置安装Tricon。1类2类危险场所对于北美危险场所应用，Tricon和相关设备必须安装在一个外壳内，以防止火灾和接触带电部件造成的人身伤害。外壳必须需要通过工具进入，如果是非金属的，必须具有适当的可燃性等级。底盘报警触点不得用于危险位置。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。只有经批准用于1类2类危险场所的这些组件才能使用：•2770H，HART模拟输入接口模块增强型低密度扩展底盘•8310，120 V电源模块•8311，24 VDC电源模块•，230 VAC电源模块•与上述I/O模块兼容的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。174第3章Tricon v9–v10系统2区欧洲危险场所的安装和维护规划与安装指南对于欧洲（ATEX）危险场所应用，Tricon和相关设备必须安装在符合EN 60529要求的防护等级最低为IP54的外壳中，外壳防护规范（IP代码）。简单地说，外壳必须提供防尘和溅水保护。此外，外壳必须符合EN 60079-15或EN 50021的适用要求。必须考虑以下几点：•机械强度•非金属外壳和外壳的非金属部件•接地或等电位连接设施必须在外壳外部贴上以下警告标签：通电时不得拆除或更换模块或电缆，除非该区域无易燃气体浓度。所有连接螺钉必须牢固拧紧，以防止松动和分离。底盘报警触点不得用于危险位置。外ELCO接头必须安装垫圈，并且必须在五年寿命结束前更换。.
• Maintain shield continuity and ensure that shield leads are not broken. Allow the minimum amount of unshielded wire that accommodates connection. Terminate the shield at both ends, use capacitive coupling at one end if potential ground loops are suspected. • Where ferrites or line filters are to be installed on signals or cables entering or leaving the cabinet, they must be installed as close to the cabinet egress point as possible. Cables must be routed to minimize coupling between the filtered and non-filtered signals. The non-filtered wire lengths in the cabinet must be minimized to the maximum extend possible. . CAUTION For applications with uninterruptible power supplies (UPS) that use AC inverters, Triconex recommends that you install an AC line filter at the cabinet power entry point for each AC power source. Select the size of the filter based on the worst-case AC load in the cabinet, and install the filter according to the Tricon Field, Power, and Ground Wiring on page 170 guidelines. Suitable filters include the Schaffner FN 350 series, or the Corcom SK series. WARNING Always turn field power off before removing ELCO connectors from the backplane of the Tricon chassis. Dangerous voltage may be present when field power is on and can cause damage to the Tricon backplane and termination panel. 172 Chapter 3 Installation and Maintenance Planning and Installation Guide for Tricon v9–v10 Systems Application-Specific Installation Guidelines The following guidelines apply when installing the Tricon in application-specific locations. Class 1 Division 2 Hazardous Locations For North American hazardous location applications, the Tricon and associated equipment must be mounted in an enclosure that provides protection from fire and from personal injury resulting from access to live parts. The enclosure must require access via a tool, and if nonmetallic, have the appropriate flammability rating. The chassis alarm contacts must not be used in hazardous locations. 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 Class 1 Division 2 hazardous locations, can be used: • 2770H, HART Analog Input Interface Module Enhanced Low Density Expansion Chassis • 8310, 120 V Power Module • 8311, 24 VDC Power Module • 8312, 230 VAC Power 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. 174 Chapter 3 Installation and Maintenance Planning and Installation Guide for Tricon v9–v10 Systems Zone 2 European Hazardous Locations For European (ATEX) hazardous location applications, the Tricon and associated equipment must be installed in an enclosure that provides an IP54 minimum degree of protection per the requirements of EN 60529, Specification of protection provided by enclosures (IP Code). Simply stated, the enclosure must provide protection against dust and splashing water. Additionally, the enclosure must meet the applicable requirements of EN 60079-15 or EN 50021. The following points must be taken into account: • Mechanical strength • Non-metallic enclosures and non-metallic parts of enclosures • Earthing or equipotential bonding connection facilities The following warning label must be placed on the outside of the enclosure: DO NOT REMOVE OR REPLACE MODULES OR CABLES WHILE ENERGIZED UNLESS THE AREA IS KNOWN TO BE FREE OF IGNITABLE GAS CONCENTRATIONS. All connecting screws must be securely tightened, so that loosening and separating are prevented. The chassis alarm contacts must not be used in hazardous locations. Male ELCO connectors must have a gasket installed, and it must be replaced before the end of its five-year life span.
