The manufacturers of explosion-proof distribution boxes should master the corresponding maintenance knowledge. In this way, when the explosion-proof distribution boxes encounter faults, they can be repaired in time to avoid more serious problems. Below, the manufacturers of explosion-proof distribution boxes share the maintenance knowledge. 
The operators of explosion-proof distribution boxes must wear anti-static clothing and must not carry empty hands or wear wet gloves. Check that the installation tools and accessories are not faulty; some tools are damaged in their protective positions, making the installation tools dangerous items. After connecting the explosion-proof distribution box to the power source, someone will check whether the circuits of the explosion-proof distribution box are energized. At this time, one must not directly touch or come into direct contact with the body. 
Additionally, when the explosion-proof distribution box is in operation, it is **impossible to dismantle or disassemble. First, disconnect the power supply, then use a testing pen to check that there is no power supply, so as to carry out the dismantling and maintenance work. If possible, repair the explosion-proof distribution box. There are many people at the scene, so even if one person has an accident, others will have the opportunity to rescue. 
If an accident occurs during the maintenance period, that would not be what we want. At the same time, we must remind our friends that the maintenance personnel should also pay attention to safety. Although explosion-proof distribution boxes have powerful functions when used in flammable and explosive places, due to various reasons, long-term use of explosion-proof distribution boxes can also lead to faults in the distribution boxes during use. This is why they need to be maintained.
