靜電敏感，某些組件比其他組件多。
為防止這些部件受到靜電損壞，必須采取特殊措施
盡量減少或消除靜電放電的預(yù)防措施。
使用或靠近控制裝置時，請遵循這些預(yù)防措施。
1、在對電子控制裝置進行維護之前，應(yīng)將靜電放電
通過觸摸和握住接地的金屬，將身體上的電接地
對象（管道、機柜、設(shè)備等）。
2、不要穿衣服，以免靜電積聚在身體上
由合成材料制成。盡可能多穿棉質(zhì)或棉質(zhì)混紡材料
因為它們不會像
合成材料。
3、保存塑料、乙烯基和泡沫塑料材料（如塑料或泡沫塑料
杯子、杯托、香煙包裝、玻璃紙包裝、乙烯基書籍或
文件夾、塑料瓶和塑料煙灰缸）遠離控制
模塊和工作區(qū)。
4、不要從控制柜上卸下印刷電路板（PCB）
除非必要。如果必須從控件中卸下PCB
機柜，請遵循以下預(yù)防措施：
•請勿觸摸PCB的任何部分，邊緣除外。
•不要接觸電導(dǎo)體、連接器或
帶有導(dǎo)電設(shè)備或手的組件。
•更換PCB時，將新PCB放在塑料防靜電盒中
在您準備好安裝之前，它會一直放在保護袋中。立即
從控制柜中卸下舊PCB后，將其放入
防靜電保護袋。
防止不當操作導(dǎo)致電子元件損壞
處理、閱讀并遵守伍德沃德手冊中的注意事項
82715，電子控制裝置的操作和保護指南，
印刷電路板和模塊。
static-sensitive, some components more than others. To protect these components from static damage, you must take special precautions to minimize or eliminate electrostatic discharges. Follow these precautions when working with or near the control. 1. Before doing maintenance on the electronic control, discharge the static electricity on your body to ground by touching and holding a grounded metal object (pipes, cabinets, equipment, etc.). 2. Avoid the build-up of static electricity on your body by not wearing clothing made of synthetic materials. Wear cotton or cotton-blend materials as much as possible because these do not store static electric charges as much as synthetics. 3. Keep plastic, vinyl, and Styrofoam materials (such as plastic or Styrofoam cups, cup holders, cigarette packages, cellophane wrappers, vinyl books or folders, plastic bottles, and plastic ash trays) away from the control, the modules, and the work area as much as possible. 4. Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If you must remove the PCB from the control cabinet, follow these precautions: • Do not touch any part of the PCB except the edges. • Do not touch the electrical conductors, the connectors, or the components with conductive devices or with your hands. • When replacing a PCB, keep the new PCB in the plastic antistatic protective bag it comes in until you are ready to install it. Immediately after removing the old PCB from the control cabinet, place it in the antistatic protective bag. To prevent damage to electronic components caused by improper handling, read and observe the precautions in Woodward manual 82715, Guide for Handling and Protection of Electronic Controls, Printed Circuit Boards, and Modules.
