WOODWARD 9907-175可编程控制卡
在安装或卸下组件之前
请断开计算机的所有电源。静电放电预防措施遵循下列预防措施：•将计算机和替换部件放在静电安全容器中运输，如导电管、袋子或盒子。•将静电敏感部件存放在容器中，直到它们到达指定的无静电工作区域。•用经批准的防静电材料覆盖指定的工作区域：–使用连接到工作表面的防静电腕带。–使用正确接地的工具和设备保持指定工作区域无非导电材料，如普通塑料辅助装配工具和泡沫包装。•避免接触引脚、引线或电路。•始终用印刷电路板（PCB）握住组件的边缘，并将组件面朝下放置。
电击危险：
卸下组件之前，请断开计算机的所有电源。未能断开电源可能会导致个人严重触电或对计算机和组件造成静电放电（ESD）损坏。注意：静电放电（ESD）会损坏静电敏感器件或微电路。•按照第23页“电压注意事项”中的详细说明，在操作计算机之前断开所有电源。•遵守正确的包装和接地技术，以防止损坏。24用于危险场所的工业计算机自动化出版物6181X-IN001D-EN-P-2015年7月预配置在拆除盖子或更换硬件组件之前，请遵循以下步骤。1.关闭计算机及其连接的所有外围设备。2.断开所有电缆与电源插座的连接，以避免暴露在高能量水平下。如有必要，为每条电缆贴上标签，以加快重新组装。3.断开电信电缆，以避免暴露于环电压的电击危险。
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.
