Matters needing attention
1.When installing the contactor, the tightening torque of the main circuit wiring screw nut is 8～10N.m;
Control circuit wiring screw nut tightening torque 1～1.5N.m.
2.The driving circuit power of the product coil must be greater than or equal to the product coil power,
Otherwise the cutting capacity of the product will be reduced.
3.The voltage continuously applied to the coil shall not exceed the maximum allowable voltage.
