The explosion-proof lamp should be checked from the nameplate and the product manual before installation: explosion-proof type, category, grade, group; protection grade of the casing; installation method and fastener requirements for installation. The installation of the explosion-proof lamp should ensure that the fixing is firm, the fastening bolts must not be replaced arbitrarily, and the spring washers should be complete.
The sealing ring for dustproof and waterproof should be placed as it is when it is installed. At the cable entry point, the cable and the sealing gasket should be closely matched. The section of the cable should be round, and the surface of the sheath should not have defects such as bumps. The excess inlet port shall be sealed according to the type of explosion-proof, and the compression nut shall be tightened to seal the inlet port.
