WARNING

Ensure that the input power is consistent with the rated value of the AC drive. Otherwise, the
AC drive will be damaged.

Ensure that the motor is adaptable to the AC drive. Failure to comply may result in motor
damage or cause trips to the AC drive.

Do not connect the power supply to the U, V, W terminals. Otherwise, the AC drive will be
damaged.
