Four: Explosion-proof positive pressure cabinets - Piano Bench Style, Explosion-proof Control Cabinets, Positive Pressure Type, Explosion-proof Distribution Cabinets - Precautions:

4.1 Check the technical data on the label to ensure it matches the usage before installing and using the product.

4.2 Cut off the power supply before installation and maintenance.

4.3 The incoming and outgoing cables must pass through a rubber seal, and they should be securely fastened with a washer and a tightening nut to ensure a seal and prevent the cables from becoming loose.

4.4 In the event of corrosion, cracking, deformation, sticking, or hardness change exceeding 20% beyond the factory setting during use, the seal ring should be promptly purchased and replaced from the manufacturer to ensure reliable explosion-proof performance.

4.5. During maintenance and disassembly, ensure that the explosion-proof surface is not bumped, scratched, or corroded, and apply 204-1 anti-rust oil regularly.

4.6 The distribution box should be checked regularly during use to ensure its proper operation.

4.7 Non-maintenance personnel are strictly prohibited from opening the cover for repair or inspection.
