保護(hù)I/O信號(hào)免受噪聲影響-布線時(shí)，將交流I/O信號(hào)線與直流I/O信號(hào)線隔離。如果這不可行，則為每組信號(hào)線使用集體屏蔽線布線時(shí)，將承載較大電流的信號(hào)線與其他信號(hào)線隔離。如果這不可行，則對(duì)承載大電流的信號(hào)線使用屏蔽線如果任何電感負(fù)載要連接到FA-M3的輸入或輸出端子，請(qǐng)?jiān)谪?fù)載附近安裝浪涌保護(hù)器或二極管。有關(guān)更多詳細(xì)信息，請(qǐng)參閱第A3.6.4小節(jié)“連接輸入設(shè)備”或第A3.6.5小節(jié)“連接輸出設(shè)備”中的“感應(yīng)負(fù)載對(duì)策”。注意，當(dāng)FA-M3在雷電頻率較高的地區(qū)使用時(shí)，請(qǐng)安裝保護(hù)設(shè)備，如電涌放電器重新檢查電源模塊的I/O規(guī)格。具體而言，請(qǐng)注意，將交流電源連接到需要直流輸入的電源模塊，并將200-240V交流電源連接至需要100-120V交流輸入的電源設(shè)備模塊，都會(huì)導(dǎo)致機(jī)器故障為避免觸電，接線前請(qǐng)關(guān)閉電源確保直流輸入電源模塊的“+”、“–”和FG端子以及交流輸入電源模塊中的L、N和FG接線端正確連接。端子螺釘和壓接端子F3PU-0S電源模塊使用M4螺釘接線板，而F3PU-0N電源模塊使用M3.5螺釘接線板。
接地程序
當(dāng)FA-M3安裝到基本模塊上時(shí)，它會(huì)自動(dòng)與基本模塊的金屬底盤接觸，因此它與控制器的信號(hào)電位和控制器的信號(hào)接地共用相同的電位。使用橫截面積超過2mm2的電線，通過盡可能短的路線連接到保護(hù)接地（符合每個(gè)國(guó)家的法規(guī)）。有關(guān)FA-M3接地線的詳細(xì)信息，請(qǐng)參閱第A3.3.2小節(jié)，與電源模塊內(nèi)噪聲濾波器的中性端子相連。LG端子接地可適當(dāng)衰減電源的共模噪聲。如果LG端子打開，噪聲濾波器的效果將降低。交流電源模塊需要保護(hù)接地。直流電源模塊需要保護(hù)接地或功能接地。當(dāng)構(gòu)建符合CE標(biāo)記的系統(tǒng)時(shí)，將LG端子連接到FG端子，并使用編織線或其他電線將這些端子接地，以確保即使在高頻下也具有低阻抗。注意：當(dāng)LG端子未連接到FG端子時(shí)，LG端子具有輸入電源電壓的一半電勢(shì)。重新檢查輸入/輸出模塊的I/O規(guī)格。請(qǐng)注意，施加超過輸入模塊最大允許輸入電壓或電流的電壓或電流，或施加超過輸出模塊最大開關(guān)容量的電壓或電壓或電流將導(dǎo)致機(jī)器故障、物理損壞或火災(zāi)危險(xiǎn)為避免觸電，接線前請(qǐng)關(guān)閉電源確保電源端子的極性正確。
Protecting I/O Signals against Noise
- Segregate the AC I/O signal lines from DC I/O signal lines when routing them. If this is not feasible, use collectively shielded lines for each group of these signal lines. - Segregate signal lines carrying larger current from other signal lines when routing them. If this is not feasible, use shielded lines for signal lines carrying large current. - If any inductive load is to be connected to an input or output terminal of the FA-M3, install a surge protector or a diode near the load. For further details, see “Inductive Load Countermeasures,” in subsection A3.6.4, “Connecting Input Devices” or “Inductive Load Countermeasures,” in subsection A3.6.5, “Connecting Output Devices.” CAUTION Install a protective device, such as a surge arrester, when the FA-M3 is to be used in a district with a high frequency of thunder.- Re-check the I/O specifications for the power supply module. Specifically, note that connecting an AC power supply to a power supply module requiring DC input and connecting a 200-240V AC power supply to a power supply module requiring 100- 120V AC input will lead to machine failure. - To avoid electrical shock, turn off the power before wiring. - Make sure that the ‘+’ , ‘–’ and FG terminals of a DC input power supply module and the L, N and FG terminals of an AC input power supply module are connected correctly.Terminal Screws and Crimp-on Terminals The F3PU??-0S power supply modules use M4-screw terminal blocks, unlike F3PU??-0N power supply modules, which use M3.5-screw terminal blocks.
Grounding Procedure
It is automatically brought into contact with the metal chassis of the base module when the FA-M3 is mounted onto the base module so it shares the same electric potential with the controller’s signal potential with the controller’s signal ground. Using a wire with a cross-section area of more than 2mm2 , connect to the Protective earth (Comply with the regulation of each country.) by taking the shortest route possible. For details onthe grounding lines of the FA-M3, see subsection A3.3.2, Is connected with the neutral terminal of the noise filter within the power supply module. Grounding the LG terminal properly attenuates the comon mode noise from the power supply. If the LG terminal is opened, the effect of the noise filter will be reduced.AC power supply module is required protective earth. DC power supply module is required protective earth or functional earth. When building a system compliant to CE Marking, connect LG terminal to FG terminal and ground these terminals with braided or other wires that ensure low impedance even at high frequencies. CAUTION LG terminal has a half potential of the input power supply voltage when LG terminal isn’t connected to FG terminal.Re-check the I/O specifications for the input/output modules. Note that applying a voltage or current that exceeds the maximum permissible input voltage or current of an input module or a voltage or current that exceeds the maximum switching capacity of an output module will lead to machine failure, physical damage or fire hazard. - To avoid electrical shock, turn off the power before wiring. - Make sure that the polarity of power terminals is correct.
