Usage Cautions

1、 This document is only for customer selection reference, AOKAI has tried the best to ensure the accuracy of the information in this document. Product specifications and parameters may be changed due to product improvement etc., they may be inconsistent because of not updated in time. For the specific parameters and performance of each product, please refer to the samples provided by AOKAI and the corresponding signed and controlled specification.

2、 Regarding the application of this product, please select the matching product according to your specific use conditions and environmental requirements when selecting the product. If the requirements are not clearly specified, please contact AOKAI to obtain more technical support.

3、 When installing and using this product, regardless of wiring or fixed installation, it is required to use anti-loose spring washers.

4、 The torque for installing fasteners should be within the standard range required by this specification. It may cause the unstable installation or damaging the product if the torque is lower than the minimum torque or higher than the maximum torque.

5、 Do not install the contactor in places with strong magnetic fields (such as transformers or strong magnets), or close to objects with thermal radiation. It is recommended to use it with a cooling fan.

6、 It is forbidden to use the product that have been dropped from a high place (height≥30cm).

7、 The driving power of the product coil must be bigger than or equal to the coil power of the product, otherwise the product switching ability will be reduced.

8、 When the coil is continuously energized, the coil voltage cannot exceed the maximum allowable voltage, otherwise the abnormal heating of the coil will affect its service life.

9、 This product is not waterproof. Please do not use it in an environment where water, solvent, or oil may come into contact with the casing or terminals. Otherwise, the aging of the casing or corrosion of the terminals may cause abnormal heating.

10、It is forbidden to use the product beyond the rated electrical life. When the rated electrical life is reached, although the product can continue to work, there is a risk of failure, explosion, and burning because of non-breaking.

11、This product cannot be used as a protector, and the circuit must be connected with a protector in series when using.

12、AOKAI only does the resistive electrical life verification and quality assurance. When the product is used in an environment with inductive load or capacitive load, it is recommended that the circuit should be connected in parallel with a surge protection device.

13、After continuous work, restarting immediately after disconnection will affect the pull-in voltage because the product is in a hot state, and the pull-in voltage will increase, which is a reasonable phenomenon.

14、It is strictly prohibited to wiring when power on.
