Be sure to use washer to prevent screws from loosening, all the terminals or copper bar must be in direct contact with the contactor’s terminals. Screw tightening torque is specified below. Exceeding the maximum torque can lead to product failure. is 7 .0 mm

• Mounting torque: 20 lb.in (2.3 N.m) 2. Contact terminals are polarized so refer to drawing during connecting. We suggest using a varistor rather than diode as a surge protector. 3. Do not use if dropped. 4. Avoid installing in a strong magnetic field (close to a transformer or magnet), or near a heat source. 5. Electrical life Use per load capability and life cycle limits so as not to cause a function failure (treat the contactor as a product with specified life and replace it when necessary). It is possible to make parts burn around the contactor once operating failure occurs. It is necessary to take layout into account and to make sure power shall be cut off within 1 second. 6. Lifetime of internal gas diffusion The contactor is sealed and filled with gas, lifetime of gas diffusion is determined by temperature in contact chamber (ambient temperature + temperature generated by contact operation). Operate only in an ambient temperature from -40 to +85 ˚C. 7. Drive power must be greater than coil power or it will reduce performance capability. 8. Avoid debris or oil contamination on the main terminals to optimize contact and avoid excess heat generation. Estimated Life (Cycles) Load Current (A)
