It can only operate under the condition that the fan is perfectly normal. At the same time, it is necessary to ensure that the capacity of the power supply facility is sufficient and the voltage is stable. It is forbidden to exceed or fall below the product voltage range. In addition, inter-phase operation is not permitted. The power line must be a dedicated line. Long-term use of temporary rows.
The operating environment of the DC cooling fan must always keep the air smooth, dry and clean. The fan surface should be kept clean and there should be no debris at the air inlet and outlet. Periodically remove dust and other debris from the fan and pipeline.
