10. Safety Precautions

1. Once the safety protection of the equipment is damaged, the equipment must be stopped and handled in accordance with the relevant maintenance regulations.
2. When the power supply equipment is moved from a cold environment to a warm environment, condensation may cause electric leakage hazards. Therefore, the grounding requirement must be strictly implemented; only qualified personnel are allowed to connect the equipment to the power supply.
3. Before conducting maintenance on the power supply equipment, the power supply must be cut off and the equipment must be shut down for 5 minutes to allow sufficient time for the capacitors to discharge.
4. Pay attention to safety in use: Avoid touching parts marked with safety warning signs or high-voltage signs to prevent electric shock or burns.
