11 9. 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. After the power supply is cut off, the equipment must be shut down for 5 minutes to allow sufficient time for the capacitors to discharge before maintenance work is performed on the power supply equipment.
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.
