What are the daily maintenance methods for AC power supply?
1. The place where the AC power supply is placed should ensure that it is used indoors with ventilation, dryness, no direct sunlight, and no corrosive gas.
2. Power-on process: Confirm that the equipment under the AC power supply in the classroom is in the shutdown state, and then turn on the power supply in turn to turn on the equipment.
3. Shutdown process: first turn off the equipment under the AC stabilized power supply, and then turn off the stabilized power supply again after confirming that it is correct.
4. The ground wire should be installed for the stabilized power supply during the safety of electricity use. For example, an alarm sound will appear after the ground wire is installed. Because the ground wire conflicts with the leakage protector you installed, the alarm sound will sound. Please remove the leakage protection you installed The protector is removed.
