  • Page 15: Compliance With Standards And European Directives

    Operating & Maintenance Instructions COMPLIANCE WITH STANDARDS AND EUROPEAN DIRECTIVES Meters are marked with the European CE mark, in accordance with the Marking Directive 93/68/EEC, to indicate compliance with the requirements of the EMC Directive 89/336/EEC. Safety requirements for meters are addressed in specific metering standards outlined below. The CE Mark does not denote compliance with the European Low Voltage Directive 73/23/EEC, which specifically excludes electricity meters.

  • Page 16: Introduction

    Communications are provided via the optical (IEC 62056-21) port and are supported by data stream mode, allowing fast reading of meter data. The A1140 permits up to 90 days of load profile data to be collected in less than 30 seconds. The RJ11 socket provides optional RS232 communications allowing remote access to the same data as the optical port.
