IS420ESWBH2A工控备件
其尺寸符合NEMA标准ICS 3-302.62-动态制动。如果负载惯性大于电机的惯性，则必须根据NEMA标准ICS 3.302.62进行计算，以确定正确的导线尺寸和DB电阻器瓦数。出版物1370-IN011B-EN-P 1370直流回路接触器和接线片套件7。以下程序描述了正确安装接线片所需的步骤。推荐使用的压缩工具是Thomas&Betts Corporation的TBM6或TBM6S型压缩工具。1.确保驱动器的电源已断开。2.仔细准备UL列出或认可和/或CSA认证电线的端部，安装适当的接线片和压接。对其余接线片/电线重复上述步骤。3.使用随接触器提供的螺钉/螺栓，将接线片连接到适当的端子。拧紧至表B中列出的扭矩要求。有关接线片和端子标识，请参阅图3。重要提示：当将螺钉/螺栓拧紧至适当值时，确保所有裸露的电线/接线片具有符合UL 508和/或CSA 22.2第14号表B接触器端子扭矩要求维护要求的适当电压间隔。1370直流接触器的构造应确保所需维护量最小。
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.
