拆下印刷電路板
除非絕對(duì)必要，否則不要從控制柜上拆下印刷電路板（PCB）。如果必須從控制柜上拆下PCB，請(qǐng)遵循以下預(yù)防措施：?請(qǐng)勿觸摸PCB的任何部分（邊緣除外）。?不要用導(dǎo)電裝置或手觸摸電導(dǎo)體、連接器或部件。?更換PCB時(shí)，將新PCB放在塑料防靜電保護(hù)袋中，直到準(zhǔn)備好安裝。從控制柜中取出舊PCB后，立即將其放入防靜電保護(hù)袋中。注意——靜電放電為了防止因處理不當(dāng)而損壞電子部件，請(qǐng)閱讀并遵守手冊(cè)82715《電子控制裝置、印刷電路板和模塊的處理和保護(hù)指南》中的注意事項(xiàng)。負(fù)載共享模塊手冊(cè)26011 6第3章安裝簡(jiǎn)介本節(jié)包含負(fù)載共享模塊的一般安裝說(shuō)明。包括環(huán)境預(yù)防措施和位置考慮因素，以確定負(fù)載分配模塊的最佳位置。其他信息包括開箱說(shuō)明、電氣連接和安裝檢查程序。
在處理負(fù)載共享模塊
“靜電放電意識(shí)”。拆下負(fù)載共享模塊時(shí)要小心。檢查裝置是否有損壞跡象，如面板彎曲或凹陷、劃痕、零件松動(dòng)或斷裂。通知托運(yùn)人任何損壞。位置注意事項(xiàng)選擇安裝位置時(shí)應(yīng)考慮以下要求：?冷卻通風(fēng)充足?維修和維修空間?防止直接暴露于水或易冷凝環(huán)境?防止高壓或高電流設(shè)備，或產(chǎn)生電磁干擾的設(shè)備?防止過(guò)度振動(dòng)?環(huán)境工作溫度范圍為–40至+70°C（–40至+158°F）請(qǐng)勿將負(fù)載分配模塊安裝在發(fā)動(dòng)機(jī)上。圖1-2是負(fù)載共享模塊的外形圖。將裝置安裝在盡可能靠近電子發(fā)動(dòng)機(jī)控制裝置的位置，但不要安裝在發(fā)動(dòng)機(jī)本身上。它可以安裝在任何位置。為了保持符合CE標(biāo)志要求，歐盟低壓指令要求負(fù)載共享模塊（LSM）安裝在EN60529中定義的IP43外殼。必須限制合格人員進(jìn)入負(fù)載共享模塊。
Remove the printed circuit board
Do not remove the printed circuit board (PCB) from the control cabinet unless absolutely necessary. If the PCB must be removed from the control cabinet, please observe the following precautions: ? Do not touch any part of the PCB (except the edges). ? Do not touch electrical conductors, connectors or components with conductive devices or hands. ? When replacing a PCB, place the new PCB in a plastic anti-static protective bag until it is ready for installation. Take out the old PCB from the control cabinet and put it into the anti-static protective bag immediately. Attention - Electrostatic discharge To prevent damage to electronic components due to improper handling, please read and follow the precautions in the manual 82715 "Guidelines for Handling and Protection of Electronic Control Devices, Printed Circuit Boards and Modules". Load sharing module manual 26011 6 Chapter 3 Installation introduction This section contains general installation instructions for the load sharing module. Include environmental precautions and location considerations to determine the optimal location of the load distribution module. Other information includes unpacking instructions, electrical connections, and installation inspection procedures.
Processing load sharing module
"Electrostatic discharge awareness". Take care when removing the load sharing module. Check the unit for signs of damage such as bent or dented panels, scratches, loose or broken parts. Notify the shipper of any damage. Location Precautions The following requirements should be considered when selecting the installation location: ? Adequate cooling and ventilation ? Maintenance and repair space ? Prevent direct exposure to water or condensation prone environments ? Prevent high-voltage or high current equipment, or equipment that generates electromagnetic interference ? Prevent excessive vibration ? Ambient operating temperature range is – 40 to+70 ° C (– 40 to+158 ° F) Do not install the load distribution module on the engine. Figure 1-2 is the outline drawing of the load sharing module. Install the unit as close to the electronic engine control as possible, but not on the engine itself. It can be installed anywhere. In order to maintain compliance with the CE mark, the EU low-voltage directive requires that the load sharing module (LSM) be installed in the IP43 enclosure defined in EN60529. Access to the load sharing module must be restricted to qualified personnel.
