Pay attention to the cleanliness of the explosion-proof surface during installation, and all the screws on the explosion-proof surface must be tightened.
Do not disassemble with points in flammable and explosive places.
When wiring, the control line should be kept away from the strong electromagnetic field. If the cable that cannot reach the corresponding distance detection bus should use an armored cable with point shielding function, and at the same time, ensure the good grounding of the shielding line.
When using the explosion-proof acousto-optic detector for a long time, its performance should be tested to ensure the integrity of the overall performance of the equipment.
