IS420ESWBH2A工控備件
其尺寸符合NEMA標準ICS 3-302.62-動態制動。如果負載慣性大于電機的慣性，則必須根據NEMA標準ICS 3.302.62進行計算，以確定正確的導線尺寸和DB電阻器瓦數。出版物1370-IN011B-EN-P 1370直流回路接觸器和接線片套件7。以下程序描述了正確安裝接線片所需的步驟。推薦使用的壓縮工具是Thomas&Betts Corporation的TBM6或TBM6S型壓縮工具。1.確保驅動器的電源已斷開。2.仔細準備UL列出或認可和/或CSA認證電線的端部，安裝適當的接線片和壓接。對其余接線片/電線重復上述步驟。3.使用隨接觸器提供的螺釘/螺栓，將接線片連接到適當的端子。擰緊至表B中列出的扭矩要求。有關接線片和端子標識，請參閱圖3。重要提示：當將螺釘/螺栓擰緊至適當值時，確保所有裸露的電線/接線片具有符合UL 508和/或CSA 22.2第14號表B接觸器端子扭矩要求維護要求的適當電壓間隔。1370直流接觸器的構造應確保所需維護量最小。
and has been sized to satisfy NEMA Standard ICS 3-302.62 - Dynamic Braking. If the load inertia is larger than that of the motor, calculations must be made to determine correct conductor sizing and DB resistor wattage per NEMA Standard ICS 3.302.62. Publication 1370-IN011B-EN-P 1370 DC Loop Contactors and Lug Kits 7 The following procedure describes the steps required to properly install the lugs. The recommended compression tool is the Thomas & Betts Corporation Compression Tool model TBM6 or TBM6S. 1. Ensure that power to the drive has been removed. 2. Carefully prepare the ends of the UL listed or recognized and/or CSA certified wire, install the appropriate lug and crimp. Repeat for remaining lugs/wires. 3. Using the screws/bolts supplied with the contactor, connect the lugs to the appropriate terminals. Tighten to the torque requirements listed in Table B. Refer to Figure 3 for lug and terminal identification. Important:When torquing the screws/bolts to the proper value, assure that all exposed electrical wires/lugs have the proper voltage spacings according to UL 508 and or CSA 22.2, No. 14. Table B Contactor Terminal Torque Requirements Maintenance The 1370 DC Contactors are constructed such that a minimum amount of maintenance is needed.
