The Model 6000 is a permanently installed purge and pressurization control system intended to provide ”pxb” purge and pressurization in accordance with IEC 60079-2. Instructions and markings are provided with the control system indicating how to install this device to the electrical enclosure to be purged and pressurized in accordance with IEC 60079-2. The purge control enclosure is composed of stainless steel. It is comprised of a cover and body, power supply and main controller, user interface, vent (see IECEx UL 15.0147X for details), optional I.S.Termination Board DIN mounted, optional temperature hub, and up to three temperature sensors when the temperature hub is provided. The power supply and main controller are housed in a flameproof (”db”) enclosure. The user interface, temperature hub, temperature sensors, and vent are intrinsically safe (”ib"). The control system enclosure contains the IS interface board, which has connection facilities for intrinsically safe circuits. The IS interface board is provided with five connection facilities that have assigned entity parameters. The component kit is comprised of the power electronics, user interface, vent, optional bushing (wiring harness), optional temperature hub, and up to three temperature sensors when the temperature hub is provided. The vent is separately certified.See Annex for additional information.
See Annex for Conditions of Certification.
Issue 1: The revision includes the additon of the pressurization system component kit, Model 6000-XX-XX-XX-CK-XX.
