4. Type of Protection The Ex p type of protection referred to as pressurized enclosure is based on the measure of purging out any explosive gases that are in a closed enclosure and then generating and maintaining a level of pressure that is higher than that of the ambient atmosphere As the pressure inside the cabinet is higher than the atmospheric pressure it is not possible at any time for explosive gases to penetrate the inside of the enclosure This creates an Ex free area in which electrical devices that are not themselves explosion proof can be mounted and operated The Motor Purge Control System described in these operating instructions functions in pressurized enclosure with leakage loss compensation technology Specifically this means that the positive pressure in an enclosure is maintained by the subsequent feeding of purge gas to compensate for the leakages from the enclosure To ensure that an explosive atmosphere that has penetrated during downtimes cannot become a danger the enclosure must be flushed with purge gas compressed air or inert gas before it is commissioned The quantity is decided on the basis of the inspection during first time operation The rate of flow is measured or determined at the pressurized enclosure s outlet Since a safe condition in the enclosure is not reached until the operating phase is started the Motor Purge Control System with its system components such as sensor module control modul
