1、Installation and maintenance of the soft starter should be carried out by qualified professionals.

2、The use of high voltage test equipment (such as megohmmeter) to test the insulation of the soft starter is strictly prohibited.

4、If the motor is required to run reversibly, a reversing contactor can be installed on the incoming side, note that it should not be installed on the output side of the soft starter.

5、After the winding motor rotor is strung with proper starter resistance to increase the starting torque, the soft starter can also be used to start the railing motor. When the motor reaches full speed and is stable, the starter resistance should be bypassed to reduce the power loss.

6. It is strictly forbidden to put the power factor compensation capacitor on the output side of the soft starter and not to switch the capacitor during the starting period.
