BBJ explosion-proof sound and light alarm precautions 

It is strictly forbidden to dismantle equipment with power on in flammable and explosive places. 

Do not damage the explosion-proof surface during installation and keep it clean. 

The fastening screws of the explosion-proof surface should be tightened evenly, and care should be taken to ensure that no wires or other foreign objects are mixed in the explosion-proof surface. 

The control line should be laid separately from the strong electromagnetic field conductor. If it cannot be avoided, the detection bus cable should use armored cable with shielded wire and ensure that the shielded wire is well grounded.
