7、应用注意事项：
●不要在接触器通电状态下，触摸负载接线端子，谨防触电危险；
Do not touch the Relay terminal when it is energized or in danger of electric shock
●当对控制回路及非金属材料做耐压测试时，应断开负载电压；
Disconnect the load voltage when the voltage withstand test is conducted on the control circuit and non-metallic materials
●避免将产品安装在强磁场的地方 (变压器或磁铁) ，或靠近热辐射的物体；
Avoid installing the product in places with strong magnetic fields (transformers or magnets) or near objects with heat radiation
●不要将杂物和油污沾到主引出端子，且外引线端子与主引出端子可靠接触，否则会造成端 子发热很厉害，导致连接电缆皮熔化；
Do not stick sundries and oil stains on the main outgoing terminal, and the external lead terminal shall be in reliable contact with the main outgoing terminal, otherwise the terminal will be heated seriously and the connecting cable will melt
●在进行动作电压测试时，不要使电压缓慢上升，请通过阶段跃进式供电方式对线圈驱动；
Please drive the coil through step power supply instead of making the voltage rise slowly during the action voltage test
●接触器各部位螺钉拧紧力矩控制在规定的范围。负载安装部位的螺母拧紧力矩为 7N.m；接 触器安装部位螺柱扭力 8-9N.m；
Install within the specified range. The tightening torque of the screws at the load installation position is 7N.m · m; The tightening torque of the screws at the installation position of the contactor is 8-9N.m
●在接触器意外跌落并受到冲击的情况下，原则上请不要继续使用；
Do not use the relay in case of accidental drop and impact.
●接触器寿命终点,即绝缘仪直流 500V 时引出负载端之间绝缘强度低至 50 兆欧。
The end point of contactor life, that is, when the DC of the insulator is 500V, the insulation strength between the outgoing load ends decline to 50mΩ
