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 is 7N.m · m; The tightening torque of the screws at the installation position of the contactor is 8-9N.m
Do not use the relay in case of accidental drop and impact.
The end point of contactor life, that is, when the DC of the insulator is 500V, the insulation strength between the outgoing load ends decline to 50mΩ
Notes:continuous output with current of 400A and lead of 300mm ² X2 wire. ( the temperature of control wire at 400A current is 85℃) Contact us if you want more details.
