WOODWARD 5466-274現(xiàn)場電纜的敷設(shè)與AC 800M連接的現(xiàn)場電纜和通信電纜的敷設(shè)無特殊要求。但是：?用于無調(diào)制解調(diào)器的短距離通信的電纜應(yīng)始終與其他電纜相距10cm（4英寸）。?連接到AC 800M的所有電纜應(yīng)與所有電力電纜相距30cm（12英寸），WOODWARD 5466-274與符合相關(guān)國際抗擾度標準4級的電纜相距10cm（4英寸）?，F(xiàn)場電纜類型在以下應(yīng)用中始終使用屏蔽電纜：?通信?高頻脈沖傳輸?低電平模擬信號，例如Pt100和熱電偶。非屏蔽電纜可用于其他應(yīng)用。信號導線和回流導線應(yīng)位于同一電纜中。防雷工業(yè)裝置和發(fā)電廠通常配有集成良好的接地網(wǎng)絡(luò)，作為配電系統(tǒng)的一部分。除非在室外環(huán)境中使用架空電線或懸掛電纜，否則此類安裝不需要額外的防雷保護。WOODWARD 5466-274
Laying Field Cables There are no special requirements for laying field and communication cables connected to AC 800M. However: ? Cables for short-distance communication without modems should always be routed at a distance of 10 cm (4 in) from other cables. ? All cables connected to AC 800M should be routed at a distance of 30cm (12 in) from all power cables and 10 cm (4 in) from cables belonging to the relevant international immunity standard, class 4. Type of Field Cable Always use shielded cables for the following applications:WOODWARD 5466-274? Communications ? High-frequency pulse transmission ? Low level analog signals, for example Pt100 and thermocouples Unshielded cables may be used for other applications. The signal and return conductor should be located in the same cable. Lightning Protection Industrial installations and power plants are normally provided with well-integrated grounding networks, installed as part of the power distribution system. Such installations do not require additional lightning protection unless using overhead wiring or suspended cables in an outdoor environment.WOODWARD 5466-274
