Руководство по эксплуатации

IS barriers БИП-1 (hereinafter – БИП-1) are intended for ensuring intrinsic safety of circuits of electro-pneumatic transducers ЭП-Ех and electro-pneumatic positioners ЭПП-Ех that are located in an explosion hazard area.

БИП-1 bears the explosion-proof marking [Ехia]IIC with the protection type “intrinsic safety “ia” and with protection level “extra-explosion-proof”, complies with requirements of GOST 12.2.007.0-75, GOST R IEC 60079-0-2011, GOST R IEC 60079-11-2010 (IEC 60079-11:2011), GOST R IEC 60079-14-2008 (EC 60079-11:2011), and is designed to be installed out of indoor and outdoor explosion hazardous areas according to requirements of PUE-99 Chapter 7.3, PTEEP (“Regulations for Operation of Consumer Electrical Installations”) Chapter 3.4, and GOST R IEC 60079-10-1-2008.

Scope of application of БИП-1 includes process monitoring and control systems at petroleum, petrochemical, and fertilize industry enterprises, and in other industries associated with refining, receipt, use, or storage of explosive mixtures, gases or vapors with air.
