Select alocation away from strong electrical and magnetic fields. If thisis not possible, particularly in applications where mobilecommunications equipment is expected to be used, screenedcables within flexible, earthed metal conduit must be used.Install in a clean, dry, well ventilated and vibration-free locationproviding easy access. Avoid rooms containing corrosive gasesor vapors, for example, chlorination equipment or chlorine gascylinders.Figure 11 Transmitter locationOptional installation accessories• Cable gland kit• Panel-mount kit• Pipe-mount kit• Weathershield144 (5.67)10(0.39)55(2.16)99 ( (3.89)73 ( (2.87)144(5.67)16(0.63)COMMUNICATIONMODULESENSORMODULELOCKED UNLOCKEDMax. cable distancetransmitter to sensor(refer to sensorOperating Instruction)0 to 95 % RHnon-condensingEye-level locationAmbient temperatureHumidityIEC 60068-2-6 Test FC: vibration, sinusoidal–20 °C(–4 °F)min.60 °C(140 °F)max.
