Safety Standards, FM Approval Safety standards used B-2 The following safety standards apply to all EX modules: EN50014 (1977 + A1 .. A5): Electrical equipment for hazardous locations: General specifications. EN50020 (1977 + A1.. A5): Electrical equipment for hazardous locations: Intrinsic safety ”i”. DIN EN 61010 (Teil 1 v. 3/94): Section 6.3.1 and Appendix D.2 Table D.6 Safety requirements for electrical measuring, control and laboratory equipment. DIN EN 61131 (Teil 2 v. 5/95): Programmable logic controllers, operational equipment requirements and testing. DIN EN 60204 (Teil 1 v. 6/93): Electrical equipment of machines: General requirements. The designations of safety characteristic values have been adapted in the course of harmonization of the standards EN50012 .. EN50020. The most important characteristic data for the relevant operational equipment are assigned as follows: Uo, Umax, Ua Uo Maximum output voltage Io, Ia, Ik Io Maximum output current Um Um Maximum r.m.s. power-frequency voltage or maximum direct voltage Co, Ca Co Maximum external capacitance Lo, La Lo Maximum external inductance P, Pmax Po Maximum output power C, Ci Ci Maximum internal capacitance L, Li Li Maximum internal inductance I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04
FM approval I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04 Safety Standards, FM Approval The assemblies are identified as follows for the purpose of arranging the explosion protection classes in groups for the American market: CL I, DIV 2, GP A, B, C, D, T 4, Ta 60C FM Explosive atmospheres can occur temporarily in CL I, DIV 2. If modules are operated in this zone, they must not be unplugged or connected during operation. B-3
