1. Full-voltage starting or reduction voltage starting are both OK for centrifugal fan,but the electric current of full-voltage starting is about 5 to 7 times to the rated current.
When electrical capacity is insufficient, reduction voltage starting is better.
2. Before centrifugal fan commissioning, check whether the wiring methods are consistent with the wiring diagram; whether the working voltage of power supply is conform to the requirements; whether the power supply is lack of phase; whether the capacity of electrical components meet the requirements.

Stop running after five minutes, and confirm no abnormal phenomenon, then start operation.
4. Check whether the input current is normal when the fan speed reach normal speed, and centrifugal fan running current should not exceed rated current.If the current exceeds its rated current operation, check whether the supply voltage is normal.
