負(fù)載共享模塊手冊26011 8屏蔽布線所有屏蔽電纜必須是帶箔或編織屏蔽的絞合導(dǎo)線。不要試圖鍍錫（焊接）編織屏蔽。應(yīng)屏蔽所有信號線，以防止拾取來自相鄰設(shè)備的雜散信號。將屏蔽連接到設(shè)備接線圖中所示的端子。暴露在屏蔽之外的電線必須盡可能短。屏蔽的另一端必須保持打開，并與任何其他導(dǎo)體絕緣。不要將屏蔽信號線與其他承載大電流的電線一起敷設(shè)。更多信息，請參見應(yīng)用注釋50532，電子調(diào)速系統(tǒng)的EMI控制。如果需要屏蔽電纜，將電纜切割至所需長度，并按照以下說明和圖3-1所示準(zhǔn)備電纜。不要在離負(fù)載分配模塊最近的一端切割屏蔽。切斷遠(yuǎn)離裝置一端的護(hù)罩。2.使用鋒利的尖頭工具小心地展開防護(hù)罩的線束。3.將內(nèi)部導(dǎo)體拉出屏蔽。扭轉(zhuǎn)編織屏蔽以防止磨損。
將接線片連接到屏蔽和控制線
大多數(shù)安裝使用6號開槽或圓形壓接端子。將導(dǎo)線連接到模塊上的相應(yīng)端子。具有嚴(yán)重電磁干擾（EMI）的安裝可能需要導(dǎo)管內(nèi)屏蔽線、雙屏蔽線或其他預(yù)防措施。手冊26011負(fù)載分配模塊9發(fā)電機(jī)連接注意：所有PT和CT連接使用1 mm2（18 AWG）或更大的導(dǎo)線。端子3和4上的接線片之間的間距必須為6.5 mm（0.256英寸）或更大，以符合歐盟低壓指令（見圖1-3）。接線片必須有絕緣套管。重要事項(xiàng)電壓互感器和電流互感器的三相連接必須正確，負(fù)載分配模塊才能正常工作。在模塊中對三相進(jìn)行排序是非常繁瑣的，需要多次啟動和停止發(fā)電機(jī)。如果可能，請確保安裝時接線正確，發(fā)電機(jī)和模塊上的相位正確且永久地標(biāo)識。將A支路的PT輸出連接到端子1。將B支路的PT輸入連接到端子2。
Load Sharing Module Manual 26011 8 Shielded Wiring All shielded cables must be stranded conductors with foil or braided shielding. Do not attempt to tin (solder) braid the shield. All signal lines shall be shielded to prevent picking up stray signals from adjacent equipment. Connect the shield to the terminals shown in the equipment wiring diagram. The wires exposed outside the shield must be as short as possible. The other end of the shield must remain open and insulated from any other conductor. Do not lay shielded signal wires together with other wires carrying large current. For more information, see Application Note 50532, EMI Control for Electronic Speed Governing Systems. If shielded cable is required, cut the cable to the required length and prepare the cable according to the following instructions and Figure 3-1. Do not cut the shield at the end closest to the load sharing module. Cut off the shield at the end away from the unit. 2. Use sharp pointed tools to carefully unfold the harness of the protective cover. 3. Pull the inner conductor out of the shield. Twist the braided shield to prevent wear.
Connect the lug to the shield and control wire
Most installations use 6 # slotted or round crimp terminals. Connect the wires to the appropriate terminals on the module. Installations with severe electromagnetic interference (EMI) may require in conduit shielding, double shielding, or other precautions. Manual 26011 Load Distribution Module 9 Generator Connections Note: 1 mm for all PT and CT connections 2 (18 AWG) or larger. The spacing between the lugs on terminals 3 and 4 must be 6.5 mm (0.256 inch) or greater to comply with the EU Low Voltage Directive (see Figure 1-3). Lugs must have insulating sleeves. Important: The three-phase connection of voltage transformer and current transformer must be correct for the load distribution module to work normally. It is very tedious to sort the three phases in the module, and the generator needs to be started and stopped for many times. If possible, please ensure that the wiring is correct during installation, and the phases on the generator and module are correct and permanently identified. Connect the PT output of branch A to terminal 1. Connect the PT input of branch B to terminal 2.
