62 For your safetyVEGABAR 82 • 4 … 20 mA45027-EN-131010radiated emissions must be taken into account, as is usual with aclass A instrument according to EN 61326-1. If the instrument is usedin a different environment, the electromagnetic compatibility to otherinstruments must be ensured by suitable measures.2.6 Measuring range - permissible processpressureThe permissible process pressure is specified on the type label with"process pressure", see chapter "Configuration". For safety reasons,this range must not be exceeded. This applies also if a measuringcell with higher measuring range (order-related) than the permissiblepressure range of the process fitting is installed.2.7 NAMUR recommendationsNAMUR is the automation technology user association in the processindustry in Germany. The published NAMUR recommendations areaccepted as the standard in field instrumentation.The device fulfills the requirements of the following NAMUR recom-mendations:• NE 21 – Electromagnetic compatibility of equipment• NE 43 – Signal level for malfunction information from measuringtransducers• NE 53 – Compatibility of field devices and display/adjustmentcomponents• NE 107 – Self-monitoring and diagnosis of field devicesFor further information see www.namur.de.2.8 Environmental instructionsProtection of the environment is one of our most important duties.That is why we have introduced an environment management systemwith the goal of continuously improving company environmental pro-tection. The environment management system is certified accordingto DIN EN ISO 14001.Please help us fulfill this obligation by observing the environmentalinstructions in this manual:• Chapter "Packaging, transport and storage"• Chapter "Disposal"
