Do not touch the relay terminal when it is energized or in danger of electric shock

Disconnect the load voltage when the voltage withstand test is conducted on the control circuit and non-metallic materials

Avoid installing the product in places with strong magnetic fields (transformers or magnets) or near objects with heat radiation

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

Please drive the coil through step power supply instead of making the voltage rise slowly during the action voltage test

Install within the specified range. The tightening torque of the screws at the load installation position is9~11N ·m; The tightening torque of the screws at the installation position of the contactor is4~5N ·m

Do not use the relay in case of accidental drop and impact
