Manufacturer is requested to strictly. observe that the supply air is between 0.35 MPa to
0.65 MPa. The pressurized explosion-proof will not operate properly without the required
amount of air pressure, if air pressure is low. If increase the air pressure, the pneumatics
equipment for the pressurized explosion-proof system will be caused for equipment dam-
age.
