Note:
 Cables of the sizes recommended for the main circuit can be used in scenarios where the
ambient temperature is lower than 40° C, the wiring distance is shorter than 100 m, and
the current is the rated current.
 The terminals (+) and PB are used to connect to braking resistors.
 If the control cable and power cable need to be crossed, ensure that the angle between
the control cable and the power cable is 90 degrees.
 If the inside of the motor is wet, the insulation resistance will decrease. If you think there is
moisture inside the motor, dry the motor and re-measure it.
C.4 Breaker and electromagnetic contactor
You need to add a fuse to prevent overload.
You need to configure a manually manipulated molded case circuit breaker (MCCB) between
the AC power supply and VFD. The breaker must be locked in the open state to facilitate
installation and inspection. The capacity of the breaker needs to be 1.5 to 2 times the rated
current of the VFD.
 According to the working principle and structure of breakers, if the
