4. REMARKS


 


1) While assemble contactor, tighten torque of nut of terminal screw in main circuit is      10~13N.m; tighten torque of nut of terminal screw in control circuit is 1~1.5N.m.


2) Driving circuit power for coil must be no less than coilpower; otherwise, it will              reduce cutting capacity of product.


3) Continuous applied voltage should not exceed the maximum permission voltage.        Otherwise, abnormal heating of coil will shorten the life of insulating coating.


4) This contactor is non-waterproof, please don’t use in water, solvent, oil and other         environment that may contact with the shell or terminal. Otherwise, it may cause         abnormal heating due to the burn-in of shell or corrosion, dirty of terminal.
