1. Turn on the main power switch and check if the device's power supply is functioning properly and if the power indicator light is on. Proceed to the next step after normal operation.

2. Close the power switch of each circuit and check if it is normal. Under normal conditions, the device is not operating, the belt line operation indicator light is not on, the power indicator light of devices such as frequency converters is on, and the display panel of frequency converters shows normal (no fault code display).

3. Start each electrical equipment in sequence according to the process flow. After the previous electrical equipment starts normally (the motor or other equipment has reached normal speed and state), proceed to the next electrical equipment start.
