5. To open an explosion-proof electronic clock, follow the guidelines on the warning label and disconnect the power supply before opening the cover.
6. After opening the cover, inspect the explosion-proof joint surface for integrity, check if the rubber seals are hardened or sticky, verify whether the wire insulation is deteriorated or carbonized, and examine if the insulation and electrical parts are deformed or charred. Address these issues with prompt repair and replacement.
7. Ensure that the specifications and characteristics of replaced lamps, parts, and electrical components are consistent with those before maintenance.
