Endura ACA5924-electrode conductivity transmitter 2 Use in Areas Requiring Ignition ProtectionOI/ACA592/EC–EN Rev. B 112 Use in Areas Requiring Ignition ProtectionSpecial regulations must be observed in explosion-protection zones for the auxiliary power connection,signal inputs/outputs and ground connection.2.1 Approvals2.1.1 CE MarkThe ACA592–EC including type B LCD display / configuration software meets all requirements for the CEmark in accordance with applicable EC Directives 2004/108/EC (EMC), 2006/95/EC (LVD) and 94/9/EC(ATEX).2.1.2 Ignition ProtectionThis transmitter is FM, CSA and ATEX/IEC approved – see Section 2.5, page 12 for hazardous arearelevant information.2.2 GroundIf for functional reasons, the intrinsically safe circuit must be grounded by connecting it to an equipotentialbonding system, it must be grounded at a single location only.2.3 InterconnectionIf ACA592 transmitters are operated in an intrinsically safe circuit, proof of interconnection may be requiredduring the installation. In general, intrinsically safe circuits require proof of interconnection.2.4 ConfigurationACA592 transmitters can be installed in hazardous areas in compliance with proof-of-interconnection anddirectly in a hazardous area using approved handheld HART terminals (proof of interconnection may berequired during the installation) as well as by coupling an ignition-proof modem to the circuit outside theexplosion-protection area.Caution. All parts must be installed in accordance with manufacturer information and relevant standardsand regulations. Startup and operation must be performed in accordance with ATEX User Directive 99/92/EC orBetrSichV (EN60079-14).
