扭矩要求
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。重要事项：当将螺钉/螺栓拧紧至正确值时，确保所有外露电线/接线片具有符合UL 508和/或CSA 22.2第14号规定的正确电压间距。表B接触器端子扭矩要求维护1370直流接触器的构造应确保所需维护量最小。作为正常使用的结果，触点最终将开始退化。定期检查这些触点应成为任何传动系统预防性维护计划的一部分。如果触点检查发现电源极触点严重腐蚀，建议更换电源极（如果可能）或接触器。更换接触器将有助于减少触点闭合不均匀和不均匀的影响。
机械完整性
如果接触器长时间未使用，应在使用前对机械完整性和触点腐蚀进行简要检查！注意：为了保持1370接触器的UL列表和CSA认证，您必须使用Thomas&Betts Corporation压缩工具TBM6或TBM6S，并遵循工具随附的说明。压接不当可能导致过热、火灾和/或人身伤害！注意：为防止人身伤害，确保在将工具手柄放在一起时，手指远离模具套。大多数压缩工具都设计有全行程强制机构，因此在初始闭合后很难释放手柄。操作前，请参考压缩工具的制造商说明。接触器负载和线路端子动态制动端子螺钉/螺栓尺寸扭矩N-m（lb-in.）螺钉/螺栓大小扭矩N-m。)
Torque requirements
Tighten to the torque requirements listed in Table B. Refer to Figure 3 for lug and terminal identification. IMPORTANT: When tightening the screws/bolts to the correct value, ensure that all exposed wires/lugs have the correct voltage spacing in accordance with UL 508 and/or CSA 22.2 No. 14. Table B Contactor Terminal Torque Requirements Maintenance 1370 The construction of the DC contactor shall ensure the minimum amount of maintenance required. As a result of normal use, contacts will eventually begin to deteriorate. Periodic inspection of these contacts should be part of any drive system preventive maintenance program. If the contact inspection shows that the power pole contact is severely corroded, it is recommended to replace the power pole (if possible) or contactor. Replacing the contactor will help reduce the effects of uneven contact closure and uneven contact closure.
Mechanical integrity
If the contactor has not been used for a long time, the mechanical integrity and contact corrosion shall be briefly checked before use! Note: In order to maintain the UL list and CSA certification of 1370 contactors, you must use Thomas&Betts Corporation compression tool TBM6 or TBM6S, and follow the instructions attached to the tool. Improper crimping may cause overheating, fire and/or personal injury! Note: To prevent personal injury, make sure that your fingers are away from the mold sleeve when putting the tool handles together. Most compression tools are designed with a full stroke forcing mechanism, so it is difficult to release the handle after initial closing. Refer to the manufacturer's instructions for the compression tool before operation. Contactor load and line terminal dynamic brake terminal screw/bolt size torque N-m (lb in.)
