In hazardous locations with explosive gases such as petroleum, chemical, and mining industries, lighting fixtures inevitably generate electrical sparks or form hot surfaces during operation. When these meet the explosive gas mixtures present at production or rescue sites, they can cause explosions. As the most widely used lighting fixtures, the usage and maintenance of explosion proof luminaire have long attracted widespread attention and high importance.

Installation of Explosion-Proof Luminaire

• Explosion-proof LED lights should be securely fixed during installation. Bolts should not be arbitrarily replaced, and spring washers should be complete.
  

• The sealing rings used for dust and waterproofing should be placed as they are during installation.

• At the cable entry, the cable and the sealing gasket should fit tightly, the cable cross-section should be round, and the sheath surface should be free from indentations and other defects.

• Spare entry points must be sealed according to the explosion-proof type and the compression nut should be tightened to seal the entry point.

Precautions of Explosion-Proof LED Lights

• Before the light fixture is put into use, it must be securely grounded internally and externally and connected to the user's on-site grounding system.

• When introducing the sealing ring of the device, ensure its reliable compression, and the cable must be tightly clamped.

• Use blocking plates and compression nuts to reliably seal unused entry points on the light fixture, ensuring the explosion-proof and protective performance is intact.

• After freshly manufactured explosion-proof lights are almost empty, they can be used normally after power-on testing.

• Avoid opening during lighting installation and maintenance while powered.

• Regularly inspect the sealing surface. If aging is found, promptly replace the light fixture. The model, specification, size, and performance of the light source, parts, and electrical components after maintenance and replacement should be completely consistent with those before the maintenance and replacement.

Maintenance of Explosion-Proof LED Lights

• Regularly remove dust and dirt from the enclosure of the explosion proof led lights to improve the lighting effectiveness and heat dissipation performance of the fixture.

• Cleaning methods can be based on the protective ability of the explosion-proof LED lights, using water spray as indicated on the fixture or wiping with a damp cloth.

• Inspect the transparent parts for any signs of impact by foreign objects, check the protective net for looseness, desoldering, corrosion, etc. If any are found, stop using the fixture and perform timely repairs or replacements.

• If the light source is damaged, promptly turn off the light and notify for replacement to prevent the ballast and other electrical components from being in an abnormal state for an extended period due to the inability to start the light source.

• During water spray cleaning, the power should be cut off. Do not use a dry cloth to wipe the transparent parts on the plastic enclosure of the light fixture to prevent static electricity.

• If there is water accumulation inside the lamp chamber of the explosion-proof LED lights used in a humid environment, it should be removed promptly and the sealing components replaced to ensure the enclosure's protective performance.

• When opening the lampshade, follow the requirements of the warning sign and open the cover after cutting off power.

• After opening the cover, inspect the explosion-proof bonding surface for intactness, check if the rubber sealing parts have hardened or become sticky, if the insulation layer of the wires has turned green or carbonized, and if there are any deformations or scorch marks on the insulating parts and electrical components. If these issues are found, perform timely repairs or replacements.

• Before closing the cover, wipe the light fixture's reflective and transparent parts with a slightly damp cloth, not overly wet, to improve lighting efficiency. Apply a thin layer of displacement anti-rust oil on the explosion-proof bonding surface. Ensure the sealing ring is in its original position to maintain the sealing effect when closing the cover.

• The sealed parts of the explosion-proof LED lights should not be frequently disassembled and opened.
