94 MountingVEGAKON 61 • Transistor (NPN/PNP)32648-EN-1708154 Mounting4.1 General instructionsMake sure that all parts of the instrument coming in direct contactwith the process, especially the sensor element, process seal andprocess fitting, are suitable for the existing process conditions, suchas process pressure, process temperature as well as the chemicalproperties of the medium.You can find the specifications in chapter "Technical data" and on thenameplate.The instrument is suitable for standard and extended ambient condi-tions acc. to DIN/EN/IEC/ANSI/ISA/UL/CSA 61010-1.Use the recommended cables (see chapter "Connecting to powersupply") and tighten the cable gland.You can give your instrument additional protection against moisturepenetration by leading the connection cable downward in front of thecable entry. For this reason, the housing can be turned without anytools by 270°. Rain and condensation water can thus drain off. Thisapplies mainly to outdoor mounting as well as installation in areaswhere high humidity is expected (e.g. through cleaning processes) oron cooled or heated vessels.To maintain the housing protection, make sure that the housing lid isclosed during operation and locked, if necessary.Make sure that the degree of contamination specified in chapter"Technical data" meets the existing ambient conditions.Fig. 3: Measures against moisture ingressThe process fitting must be sealed if there is gauge or low pressure inthe vessel. Before use, check if the seal material is resistant againstthe measured product and the process temperature.The max. permissible pressure is specified in chapter "Technicaldata" or on the type label of the sensor.Suitability for the processconditionsSuitability for the ambientconditionsMoisturePressure/Vacuum
