在安裝或卸下組件之前
請斷開計算機的所有電源。靜電放電預防措施遵循下列預防措施：?將計算機和替換部件放在靜電安全容器中運輸，如導電管、袋子或盒子。?將靜電敏感部件存放在容器中，直到它們到達指定的無靜電工作區域。?用經批準的防靜電材料覆蓋指定的工作區域：–使用連接到工作表面的防靜電腕帶。–使用正確接地的工具和設備保持指定工作區域無非導電材料，如普通塑料輔助裝配工具和泡沫包裝。?避免接觸引腳、引線或電路。?始終用印刷電路板（PCB）握住組件的邊緣，并將組件面朝下放置。
電擊危險：
卸下組件之前，請斷開計算機的所有電源。未能斷開電源可能會導致個人嚴重觸電或對計算機和組件造成靜電放電（ESD）損壞。注意：靜電放電（ESD）會損壞靜電敏感器件或微電路。?按照第23頁“電壓注意事項”中的詳細說明，在操作計算機之前斷開所有電源。?遵守正確的包裝和接地技術，以防止損壞。24用于危險場所的工業計算機自動化出版物6181X-IN001D-EN-P-2015年7月預配置在拆除蓋子或更換硬件組件之前，請遵循以下步驟。1.關閉計算機及其連接的所有外圍設備。2.斷開所有電纜與電源插座的連接，以避免暴露在高能量水平下。如有必要，為每條電纜貼上標簽，以加快重新組裝。3.斷開電信電纜，以避免暴露于環電壓的電擊危險。
Before installing or removing components
Please disconnect all power from the computer. Electrostatic discharge precautions Observe the following precautions: ? Transport the computer and replacement parts in electrostatic safe containers, such as conductive tubes, bags, or boxes. ? Store static sensitive parts in containers until they reach the designated static free work area. ? Cover the designated work area with an approved anti-static material: – Use an anti-static wrist strap connected to the work surface. – Use properly grounded tools and equipment to keep the designated work area free of non-conductive materials, such as ordinary plastic auxiliary assembly tools and foam packaging. ? Avoid touching pins, leads or circuits. ? Always hold the edge of the component with the printed circuit board (PCB) and place the component face down.
Electric shock hazard:
Before removing components, disconnect all power from the computer. Failure to disconnect the power supply may cause serious personal electric shock or electrostatic discharge (ESD) damage to the computer and components. Note: Electrostatic discharge (ESD) may damage electrostatic sensitive devices or microcircuits. ? Disconnect all power supplies before operating the computer as detailed in "Voltage Precautions" on page 23. ? Observe correct packaging and grounding techniques to prevent damage. 24 Industrial Computer Automation Publication 6181X-IN001D-EN-P-2015 for use in hazardous locations Pre configured July Please follow the steps below before removing covers or replacing hardware components. 1. Turn off the computer and all attached peripherals. 2. Disconnect all cables from the power socket to avoid exposure to high energy levels. If necessary, label each cable to speed up reassembly. 3. Disconnect the telecommunication cable to avoid the risk of electric shock exposed to the ring voltage.
