1. Explosion-Proof Markings

Explosion-proof designations, hangē ko e “Exd II CT6,” ʻOku totonu ke fakaʻilongaʻi mahino pe li ki tuʻa ʻa e meʻangaue.

2. Product Nameplate

• Explosion-proof markings;

• Fika ʻo e tohi fakamoʻoni ʻo e fakaʻauha;

• Fakaʻilonga ʻo e laiseni;

• Ngaahi fie maʻu pau;

• ʻAho ʻo e faʻu/fika fakahokohoko.

3. Overall Appearance

• Explosion-proof metal enclosures: Ensure wall thickness and surface finish (casting and argon welding) are smooth and free from irregularities to meet explosion strength standards and porosity requirements.

• Larger products should maintain effective heat dissipation and meet temperature classification needs to extend service life.

• Equipment should feature both internal and external grounding with clear grounding indications.

• Check the configuration of electrical entry devices to support necessary construction wiring.

4. Structural Rationality

Components such as decoder boxes and power supply units should accommodate a specific number of circuits and the maximum allowable current and power.
