以太网交换机入门说明书
Figure 1: Fire or Combustion Triangle When it comes to engineering, the design must meet the criteria of the classified location. Basically, there are three techniques to avoid a fire or explosion: containment (explosion proof enclosures and fittings), segregation (purge and pressurization of enclosures),Table 4: Class/Division System Compared to Zone System.*The -ER suffix indicates additional crush and impact test requirements and can be used as ‘exposed’ or ‘open’ wiring. When coming out of the cable tray, and the connection is less than six feet away to an end device such as a motor, cables with an ER rating can be used if they are properly supported and given adequate mechanical protection. Mechanical protection consists of struts, angle, or channels.In addition to the approved cable types there are other acceptable wires/cables that can be used with the proper pathway. Any suitable type of wire or cable can be used if installed in threaded metallic conduit with approved termination fittings. Defining ‘suitable’ type of wire is the responsibility of the AHJ but typically wire or cable approved for unclassified (non-hazardous) will be accepted. Many common off the shelf industrial devices, such as network switches, PLC’s, 24V DC power supplies, and Panduit 24V UPS are rated for Class I Division 2 locations. These devices are designed and manufactured to minimize the risk by addressing factors like spacing, fuses, relays, connectors, and surface temperatures. Manufactures may have a separate model that conforms to CID2 but in many cases there may be only one version. It is common for these devices to not be mounted in the hazardous area, but they have the certification regardless.Class I Division 2Reference ➢ Threaded rigid metal conduit or threaded steel intermediate metal conduit➢ Type PLTC and PLTC-ER (Power Limited Tray Cable – Exposed Run)*Article 725 ➢ Type ITC and ITC-ER (Instrumented Tray Cable – Exposed Run)*Article 727 ➢ Type MC (Metal Clad)Article 330 ➢ Type MV (Medium Voltage)Article 328 ➢ Type TC and TC-ER (Tray Cable – Exposed Run)*Article 336 ➢ Optical Fiber cable types allowed: OFNP , OFCP , OFNR, OFCR, OFNG, OFCG, OFN & OFC Installed in raceways that meet Article 501 requirementsArticle 770Table 6: CID2 Wiring MethodsClass I Division 2 (NEC Article 501)This classification is the most common hazardous environment. Methods that are approved for CID1 are allowed for CID2 locations as CID1 construction is more stringent than C1D2 construction. Division 2 includes additional cable types that can be used since there is less exposure to the hazard. Cable types such as Power Limited Tray Cable (PLTC) must be mounted in cable tray with listed fittings to meet the requirements. Cables with a proper sheath, Metal Clad for example, can be mounted without a pathway as long as the cable run is properly supported. Table 6 summarizes these methods and provides the NEC article reference where more information can be found on a specific cable type. For each type of cable listed there are installation requirements that are described as part of Article 501.NonincendiveNonincendive is not a common term but it is another type of classification for hazardous areas. There are a several types of ‘Nonincendive’ (circuit/component/equipment/field wiring) as defined in the NEC Article 100. Nonincendive is defined as having electrical/electronic equipment that is incapable, under normal operating conditions, of causing ignition of the surrounding atmosphere due to arcing or thermal means. Normal operating conditions are defined as maximum voltage under open circuit conditions and maximum current under short circuit conditions. Nonincendive devices are approved for use in a Division 2environment (also can be used for Class III Division 1) and therefore do not require protection such as an explosion proof enclosure or an intrinsically safe barrier. An advantage of this approach is cost when compared to Intrinsically Safe and explosion proof options. Nonincendive field wiring shall be permitted using any of the wiring methods permitted for unclassified locations and installed according to the control drawing.An example of a nonincendive device for CID2 is the Panduit VeriSafe ™ Absence of Voltage Tester (AVT), see figure 2. This rating allows the device to be mounted in control panels that are in the classified area. Any type of non-hazardous wiring can be used provided the manufacturer’s installation instructions are followed.Standards Apply to VS-AVT2 OnlyISA 12.12.01Nonincendive Electrical Equipment rated for Class I, Division 2 area classification, Groups A, B, C, D, and temperature classification T3.Class III (NEC Article 503)Class III focuses on textile mills where easily ignitable fibers/flyings are present in the manufacturing process. Examples of other Class III areas include cotton gins and seed mills, flax producing or handling facilities, pulverizing or shaping plants, and clothing manufacturing facilities. Sawmills and other woodworking plants where combustible fibers/flyings are present may also become hazardous locations. Fibers/flyings are hazardous because they are easily ignited but also because flames quickly spread through them. Class III locations do not have material group designations. Table 8 summarizes these acceptable methods for Class III division 1 and 2.Intrinsically Safe (NEC Article 504)Intrinsically safe equipment is defined as equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to create a hazardous situation. Intrinsically safe systems commonly use a standalone barrier that contains energy limiting electronics. Conceptually, the function of an intrinsically safe barrier is like that of a fuse or circuit breaker. When too much energy is detected from the barrier the barrier will react and ‘open’ the circuit. Any of the wiring methods for unclassified (non-hazardous) locations can be used as long as the conditions specified in the control drawings are followed. The intrinsically safe application is viewed as a circuit and each device that is part of the system must follow the design. Control drawings are typically supplied with the intrinsically safe barrier and will specify the requirements of the cabling. It is also important that the intrinsically safe wire is isolated and clearly marked so that it is not accidentally mixed with other wiring. Typically, intrinsically safe wire is blue in color and labeled so it can be easily recognized. For more information on intrinsic safety refer to UL 698A and/or NEC article 504.Class III Division 1 and Division 2➢ Rigid metal conduit, PVC conduit, RTRC conduit, intermediate metal conduit, electrical metallic tubing, dust tight wireways➢ Type MC or MI cable with listed termination fittings ➢ Type PLTC and PLTC-ER cable ➢ Type ITC and ITC-ER➢ Type MC, MI, MV, TC/TC-ER cable (requires ventilation and specific spacing)Table 8: Class III Wiring MethodsSummaryThe NEC has an abundance of information and guidance for hazardous locations found in Chapter 5 (Article 500 to 506). Traditionally the NEC has followed the Class/Division segmentation but with the addition of Article 505 and 506 there is now a reference to the Zone schema that is used internationally. When installing outside of the United States be sure to follow the standards and regulations for that area, ATEX and IECEx are common outside of the US. Direct cross referencing of standards is usually not allowed unless the device is provided with a dual rating. Be aware that there are differences between Classes and Divisions that are not incremental and do not transfer from one to the other. For example, a Class I device cannot be used in a Class III area unless it has been rated for that area.Appropriate materials selection and installation practices are documented in the NEC and are used to create a safe design that can be approved by the authority having jurisdiction. Following these 3 steps will provide a proper install; determine the correct hazardous area classification, review the wiring types allowed for proper cable selection, and installing the cable per the requirements of the hazardous location. Each classified area has a list of approved wiring methods as shown in the tables within this paper. Additional details for the applicable standards of these wiring methods should be researched prior to developing a design. Interpretations of the requirements are subjective, so it is crucial to include any local codes and communicate with the proper authority for the specific location. In most cases there are several options available and having the proper information will result in a successful project.Panduit ProductsIt is challenging to generally classify products due to the many details and the variety of standards that apply to different situations. The FAQ section and chart below provides guidance for common situations and a starting point for product specification. Today there are many products that offer Class I Division 2 ratings; this provides more flexibility when installing in a hazardous location.What type of enclosure is needed for Class I Division 2? Can a Panduit Zone enclosure be used?In CID2 locations, enclosures, fittings, and joints are not required to be explosionproof if they contain no arcing devices and the equipment used in the panel is CID2 rated. Control panels containing solid-state relays, solenoids, and control transformers (as long as the devices operating temperature doesn’t exceed 80% of ignition temperature) are considered non-arcing devices per article 501.105(B)(3 and 4). Therefore, a NEMA 4 rated Zone Enclosure with CID2 rated equipment, such as a Stratix® switch or PLC, can be mounted in the CID2 classified area without the need for an explosion proof rating. This guidance is assuming that the area of installation does NOT require explosion proof seal. Division 2 wiring methods indicated in Article 501.10(B) must be adhered to for the installation.Additionally, some motor control devices that are mounted in control panels can have CID2 ratings. For example, devices suchas circuit breakers/motor controllers/switches that are sealed and not arc producing can be listed as CID2 rated devices. Article 501.115 and 501.120 provide more details on the exceptions but reviewing any equipment’s labeling and/or manuals will statethe rating to which it has been tested and certified.What rating is required for cables and connectors used in a Class I Division 2 control panel?Cables and connectors used in a CID2 control panel, not requiring explosion proof seal, do not have to have a hazardous location listing. As long as the equipment is ‘listed’ it can be used. To clarify, there are two types of terminology used in the NEC code;‘listed’ and ‘listed for the location’. Listed for the locations typically refers to an item being rating for the explosion proof area. However, the term ‘listed’ refers to a more general recognition such as general purpose or ordinary. The term ‘listed’ refers to a component that is tested to a standard by a Nationally Recognized Testing Laboratory such as UL or CSA. Therefore, for these CID2 control panels, Panduit network products such as patch cables, RJ45 plugs/jacks, and related equipment that are used inside the control panel are allowed. Any type of wiring that is outside of the enclosure must adhere to the Division 2 wiring methods indicated in Section 501.What type of fittings are needed for Class I Division 2 installations for Zone Enclosures (or other control panels)? Generally speaking, if the installation requires an explosionproof seal, the fitting must be an explosionproof fitting, rated, listed, and marked for either Class I, Division 1 or Class I, Division 2. If the installation does not require an explosionproof seal, all that is required is an ordinary or general-purpose rated and listed fitting compatible with the appropriate Division 2 wiring method being used. When equipment being installed does not rely on an explosionproof method of protection and does not have ignition concerns then explosionproof enclosures and fittings are not needed per section 501.10(B)(4) of the NEC.What cable can be used inside threaded metal conduit that meets Class I applications?Standard Panduit enterprise or industrial copper cable and fiber can be used in threaded rigid metal conduit. The media used in this pathway only needs to be listed (general recognition) and is not required to have any type of explosion proof rating. The threaded metal conduit provides the protection requiredMore Meaningful Connections11 WHITE PAPER – Specifying Cable Infrastructure in Hazardous Locations Per NEC StandardsThis chart contains Panduit products that can be installed in different types of hazardous locations.Part Number DescriptionApplications Type of use in hazardous locationClass IDiv 1Class I Div 2Class II Div 1Class II Div 2Class III Div 1&2IURHT5C04BL-UG Category 5e 4-pair UTP 600 V 22 AWG solid Type PLTC*Ethernet Networks EtherNet/IPRMC Cable Tray RMC Cable Tray Cable Tray ESFLHT5C02FGR-X Category 5e 2-pair SF/UTP 600 V 22 AWG stranded Type AWM, ITC, PLTC*Ethernet Networks PROFINET Type B/C RMC Cable Tray RMC Cable Tray Cable Tray ESFLHT5C02GR-X Category 5e 2-pair SF/UTP 22 AWG solid Type PLTC*Ethernet Networks PROFINET Type A RMC Cable Tray RMC Cable Tray Cable Tray UPS00100DC Maintenance-free, No battery, 100 Watts, 24VDCPower back up for 24VDC devices Not Rated Yes Not Rated Yes Yes Z22U-S14 and -S15Universal Network Zone EnclosureHousing network switches and devices Not RatedYes**Not Rated Yes**Yes**Z23U-S24 and -S25FODPZ12Y OFNP plenum, 50µm OM4, 900µm buffered fibersIndoor Distribution fiberCable Tray FODPZ24Y FSDP912Y OFNP plenum, 50µm OS2, 900µm buffered fibersIndoor Distribution fiberCable Tray FSDP924Y FOPPZ12Y OFCP plenum, 50µm OM4, 900µm buffered fibersIndoor Distribution interlocking armor Cable Tray FOPPZ24Y FSPP912Y OFCP plenum, 9µm OS2, 900µm buffered fibersIndoor Distribution interlocking armor Cable Tray FSPP924Y FOCPZ12Y OFNP plenum, 50µm OM4, 250µm fibers Indoor/outdoor loose tube cableCable Tray FONPZ24Y FSCP912Y OFNP plenum, 9µm OS2, 250µm fibers Indoor/outdoor loose tube cable Cable Tray FSNP924Y FSJD912OFNR-LS riser LSZH, OS2Industrial Dielectric Double Jacketed Cable Tray FOJDZ12OFNR-LS riser LSZH, OM4Industrial Dielectric Double JacketedCable Tray* Power Limited Tray Cable (PLTC) applications reduce rating to 300 V ** When equipped with location approved equipmentAWM = Appliance Wiring Material ITC = Instrument Tray cable PLTC = Power Limited Tray CableRMC = Rigid Metal Conduit (thick walled threaded metal tubing)OFCP = Fiber Optic Conductive Plenum OFNP = Fiber Optic Nonconductive PlenumOFNR-LS = Fiber Optic Nonconductive Riser LSZH = Low smoke Zero HalogenCable tray = Unit or assembly of units and the associated fittings that form a structural system used to securely fasten or support cables and raceways.
