4、 Attention:

1. It is strictly prohibited to dismantle with electricity in flammable and explosive places;

2. 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 attention should be paid to not containing wires or other foreign objects on the explosion-proof surface;

3. 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;

4. Regularly check the performance of the explosion-proof fire sound and light alarm, and if it fails or is damaged, it should be repaired by personnel.
