連接電源注意事項? 您必須使用24 Vdc輸入裝置和2級電源。? 要提高抗電磁噪音的能力，請確保在將電源線連接到電源插頭之前，先扭動電源線的兩端。? 面板的電源線不應(yīng)與主電路線（高壓、大電流）或輸入/輸出信號線捆綁或靠近主電路線。? 連接避雷器以處理電涌。? 為了減少電磁噪音，請盡可能縮短電源線。電源連接向面板供電時，請將輸入/輸出線和電源線分開，如圖所示。? 將浪涌吸收器（E1）與面板（E2）分開接地。? 選擇最大電路電壓大于電源峰值電壓的浪涌吸收器。如果提供的電壓超過面板范圍，請連接恒壓變壓器。避免對電源電纜施加過大的力，以防止意外斷開? 將電源電纜牢牢連接到HMIGTO或機(jī)柜。? 使用指定的扭矩擰緊裝置接線盒螺釘。? 在連接電源和通信線之前，將HMIGTO安裝并緊固在安裝面板或機(jī)柜上。? 將浪涌吸收器（E1）與面板（E2）分開接地。? 選擇最大電路電壓大于電源峰值電壓的浪涌吸收器。如果提供的電壓超過面板范圍，請連接恒壓變壓器。在線路和接地之間選擇低噪聲電源。如果噪音過大，請連接絕緣變壓器。使用容量超過功耗值的恒壓和絕緣變壓器。
專用接地
向面板供電時，按如下所示分開輸入/輸出和電源線。將電源插頭上的機(jī)架接地（FG）端子連接到專用接地。預(yù)防措施如果設(shè)備接地不當(dāng)，可能會產(chǎn)生電磁干擾（EMI）。EMI會導(dǎo)致通信中斷。除下述授權(quán)配置外，請勿使用公共接地。如果無法單獨接地，請使用公共接地點。正確接地錯誤接地? 檢查接地電阻是否小于100Ω*1.? FG導(dǎo)線的橫截面積應(yīng)大于2 mm2（AWG 14）（1）。創(chuàng)建盡可能靠近配電盤的連接點，并使導(dǎo)線盡可能短。使用長接地線時，請將細(xì)導(dǎo)線更換為粗導(dǎo)線，并將其放置在導(dǎo)管中。? FG和SG端子在面板內(nèi)部連接。當(dāng)使用SG端子將外部設(shè)備連接到面板時，請檢查在設(shè)置系統(tǒng)時是否不會產(chǎn)生短路回路*1遵守當(dāng)?shù)匾?guī)范和標(biāo)準(zhǔn)。確保接地連接的電阻為100Ω，接地線的橫截面至少為2 mm2或AWG 14。使用HMIGTO和SD卡時，請遵守以下規(guī)定，以避免丟失有價值的數(shù)據(jù)：? 由于隨時可能發(fā)生意外數(shù)據(jù)丟失，請定期備份HMIGTO屏幕和SD卡數(shù)據(jù)。HMIGTO數(shù)據(jù)一旦丟失，將無法恢復(fù)。? 在從HMIGTO中卸下SD卡之前，請使用SD卡卸下過程停止對其進(jìn)行的所有操作。如果不運行刪除過程并強(qiáng)制提取SD卡，SD卡上的數(shù)據(jù)可能會損壞。? 訪問SD卡時，不要關(guān)閉或重置HMIGTO，也不要插入或取出SD卡。這樣做可能會損壞SD卡或損壞其數(shù)據(jù)。? 使用SD卡之前，請熟悉SD卡的正面和背面方向，以及SD卡連接器的位置。如果SD卡插入HMIGTO時未正確定位，則卡的內(nèi)部數(shù)據(jù)和HMIGTO可能會損壞。
Connecting the Power Supply
Precautions ? You must use a 24 Vdc input unit with a Class 2 power supply. ? To increase the electromagnetic noise resistance, make sure that you twist the ends of the power cord wires before connecting them to the power plug. ? The panel's power supply cord should not be bundled with or kept close to main circuit lines (high voltage, high current), or input/output signal lines. ? Connect a lightning surge absorber to handle power surges. ? To reduce electromagnetic noise, make the power cord as short as possible. Power Supply Connections When supplying power to the panel, separate the input/output and power lines, as shown.? Ground the surge absorber (E1) separately from the panel (E2). ? Select a surge absorber that has a maximum circuit voltage greater than that of the peak voltage of the power supply. If the supplied voltage exceeds the panel range, connect a constant voltage transformer.Avoid excessive force on the power cable to prevent accidental disconnection ? Securely attach power cables to the HMIGTO or cabinet. ? Use the designated torque to tighten the unit terminal block screws. ? Install and fasten the HMIGTO on installation panel or cabinet prior to connecting power supply and communication lines.? Ground the surge absorber (E1) separately from the panel (E2). ? Select a surge absorber that has a maximum circuit voltage greater than that of the peak voltage of the power supply. If the supplied voltage exceeds the panel range, connect a constant voltage transformer.Select a power supply low in noise for between the line and ground. If there is an excess amount of noise, connect an insulating transformer.Use constant voltage and insulating transformers with capacities exceeding the Power Consumption value.
Exclusive Grounding
When supplying power to the panel, separate the input/output and power lines as shown below. Connect the frame ground (FG) terminal on the power plug to an exclusive ground. Precautions Electromagnetic Interference (EMI) can be created if the devices are improperly grounded. EMI can cause loss of communication. Do not use common grounding, except for the authorized configuration described below. If exclusive grounding is not possible, use a common grounding point. Correct grounding Incorrect grounding ? Check that the grounding resistance is 100 Ω or less.*1 ? The FG wire should have a cross sectional area greater than 2 mm2 (AWG 14) (1). Create the connection point as close to the panel as possible, and make the wire as short as possible. When using a long grounding wire, replace the thin wire with a thicker wire, and place it in a duct. ? FG and SG terminals are internally connected in the panel. When connecting an external device to the panel using the SG terminal, check that you do not create a short-circuit loop when you set up the system. *1 Observe local codes and standards. Ensure that the ground connection has a resistance of 100 Ω and that the ground wire has a cross-section of at least 2 mm2 or AWG 14.When using the HMIGTO and a SD card, observe the following to avoid losing valuable data: ? Since accidental data loss can occur at any time, back up HMIGTO screen and SD card data regularly. Once HMIGTO data is lost, it cannot be recovered. ? Before removing the SD card from the HMIGTO, stop all operation on it using the SD card removal process. If you do not run the removal process and forcibly extract the SD card, data on the SD card may become corrupted. ? While a SD card is accessed, do not turn OFF or reset the HMIGTO, and do not insert or remove the SD card. Doing so could damage the SD card, or corrupt its data. ? Before using the SD card, familiarize yourself with the SD card's front and rear face orientation, as well as the position of the SD card connectors. If the SD card is not positioned correctly when inserted into the HMIGTO, the card's internal data and HMIGTO could become damaged.
