Electrical control cabinet installation need to pay attention to the following safety issues:

1. Power off operation: Before installation, be sure to cut off the power supply and hang a clear "Do not close" sign to prevent accidental power transmission and electric shock.

2. Personal protective equipment: Installation personnel should wear insulation gloves, insulation shoes and other protective equipment to reduce the risk of electric shock.

3. Tool inspection: Ensure that the tools used are intact, especially power tools, and check whether their insulation performance is good.

4. Prevent short circuit: In the wiring process, to avoid the wire contact with each other, resulting in short circuit.

5. Fire and explosion-proof: For the environment where there may be flammable and explosive gas or dust, electrical control cabinets and components that meet the explosion-proof requirements should be selected.

6. Esd prevention: When operating sensitive electronic components, take ESD preventive measures, such as wearing an ESD bracelet.

7. Heavy load handling: When handling heavy objects such as the control cabinet, pay attention to prevent smashing and crushing injuries.

8. Climbing operation: If climbing installation is required, use stable climbing equipment and fasten the safety belt.

9. Electrical grounding: Ensure that the grounding of the control cabinet is reliable to prevent electric shock caused by leakage.

10. Environmental safety: The installation site should be kept dry and clean to avoid water, debris, etc., resulting in slip or other accidental injuries.

11. Training and qualification: The installation personnel should be professionally trained and have the corresponding electrical installation qualifications and skills.

12. Follow the operation procedures: strictly follow the installation and operation procedures of the electrical control cabinet, and do not change the operation steps at will.
