If in a dangerous area, ventilation and removal of flammable gases and other measures should be taken in advance to make the working environment meet the safety requirements.

3. Select the appropriate model: The model, specification, performance parameters, etc. of the new explosion-proof starter should match the original equipment and meet the actual work requirements and the explosion-proof requirements of the on-site environment.

4. Installation qualification: The installation work should be carried out by personnel with corresponding qualifications and professional skills, following the relevant installation specifications and standards.

5. Correct wiring: When connecting the lines, it is necessary to ensure that the wiring is correct and firm, and to avoid loose connections and wrong connections to prevent faults or safety accidents.

6. Sealing and fastening: After installation, it is necessary to check the sealing and fastening conditions of the shell, inlet, outlet and other parts of the explosion-proof starter to ensure its explosion-proof performance.

7. Grounding protection: Ensure that the grounding system of the explosion-proof starter is well connected to ensure the safety of the equipment and personnel.

8. Debugging and testing: After the installation is completed, debugging and testing are required to check whether the various functions of the starter are normal and whether the electrical parameters meet the requirements.

9. Acceptance and recording: After the replacement is completed, it should be accepted by professional personnel, and the replacement process and relevant parameters should be recorded and filed for future reference.

10. Safety signs: Set obvious safety signs and warning signs near the installed explosion-proof starter.
