3. Corrosion resistance and protection function: consider the corrosion resistance and protection function of explosion-proof products. In harsh environmental conditions explosion-proof products need to be able to withstand the attack of chemicals, humidity and corrosive gases. Choose products with corrosion resistant materials and good protection.
4. Safety certification: to ensure that the selected explosion-proof products meet the relevant safety standards and certification requirements, such as explosion-proof certification, explosion-proof grade certification, etc. These certifications ensure the quality and safety of the product.
5. Installation and maintenance: The installation and maintenance of explosion-proof electrical equipment shall comply with specific safety specifications. The type, grade, group, environmental conditions and special marks of the equipment shall conform to the design regulations. The shell and transparent part of the equipment shall be free from cracks, damage, fastening bolts shall be taken anti-loosening measures, free from loosening and rust. The electrical equipment shall be installed on a support made of metal, the support shall be firm, the fixing bolts of vibrating electrical equipment shall have an anti-loosening device. The internal cables of the junction box should be secured. The electrical gap and creepage distance between the exposed live part should meet the requirements of safety regulations.
6. Use under specific conditions: explosion-proof certificate number suffix "U" symbol of the product used with other electrical equipment or systems, should be first additional certification before installation and use. Where is numbered with the suffix "X", should be noted for the specific conditions of its safe use.
7. Read the user manual before installation. If you encounter difficulties during installation, do not attempt any unauthorized handling of the equipment. Please contact our services department.
