6. Installation and Maintenance
Installation
- Ensure installation is carried out after power is cut off.
- Use bolts of appropriate specifications for fastening to avoid poor contact due to looseness.
- Avoid installation in high-temperature, humid or corrosive gas environments.
Maintenance
- Regularly check the bolt tightness and the surface condition of the fuse.
- Record the time, cause and fusing current of each fusing event as the basis for subsequent analysis.
- If the shell is deformed, bolts are loose or the fuse wire is excessively ablated, replace it immediately.
