ICS TRIPLEX T8431C通訊卡件中文資料:
ICS TRIPLEX T8431C通訊卡件除了以下基本信息外,我們強(qiáng)烈建議您遵守適用于您所在地區(qū)的所有適用規(guī)范。例如,在美國(guó),大多數(shù)地區(qū)都采用了國(guó)家電氣規(guī)范標(biāo)準(zhǔn),并規(guī)定所有布線都符合其要求。在其他國(guó)家,將適用不同的規(guī)范。為了確保人員和財(cái)產(chǎn)的最大安全,您必須遵守這些規(guī)范。未能做到這一點(diǎn)可能意味著人員受傷或死亡、財(cái)產(chǎn)損失或兩者兼而有之??删幊踢壿嬁刂葡到y(tǒng)的所有部件及其控制的設(shè)備必須正確接地。ICS TRIPLEX T8431C這一點(diǎn)特別重要,原因如下。?從系統(tǒng)所有部件到接地的低電阻路徑可在發(fā)生短路或設(shè)備故障時(shí)最大限度地減少電擊。?Series 90-30 PLC系統(tǒng)需要正確接地才能正確運(yùn)行。接地導(dǎo)體?接地導(dǎo)體應(yīng)以樹(shù)形方式連接,分支布線至中心接地點(diǎn),如下圖所示。這確保了沒(méi)有接地導(dǎo)體從任何其他分支輸送電流。該方法如下圖所示。ICS TRIPLEX T8431C
英文資料
In addition to the following grounding information, we strongly urge that you follow all applicable codes that apply to your area. For example, in the United States, most areas have adopted the National Electrical Code standard and specify that all wiring conform to its requirements. In other countries, different codes will apply. For maximum safety to personnel and property you must follow these codes. Failure to do so can mean injury or death to personnel, damage to property, or both. All components of a programmable logic control system and the devices it is controlling must be properly grounded. This is particularly important for the following reasons. ? A low resistance path from all parts of a system to earth minimizes exposure to shock in the event of short circuits or equipment malfunction. ? The Series 90-30 PLC system requires proper grounding for correct operation. Ground Conductors ? Ground conductors should be connected in a tree fashion with branches routed to a central earth ground point, shown in the figure below. This ensures that no ground conductor carries current from any other branch. This method is shown in the following figure.ICS TRIPLEX T8431C
