2. OPERATING INSTRUCTIONS RC102C Please maintain these instructions and review them prior to using the unit awarniea 1 This unit is panel mounted type with its output terminals getting connected to the host equipment Such equipment shall also comply with basic EMI EMC and safety requirements like BSEN 61326 1 and BSEN 61010 respectively 2 To avoid electric shock power supply of the unit should be kept off while wiring Wiring should be done strictly as per the terminal layout given in the manual 3 Use lugged terminals to meet M3 5 screws 4 The unit does not have a built in fuse External fuse with a rating of 275 VAC 1A is recommended ACaution 1 This unitis notintended for outdoor use 2 The power connection cable must have a cross section of atleast 1mm and insulation capacity of atleast 1 5kV 3 The output connections must not be loaded beyond the specified values range 4 Avoid inflow of dust and contact of conductive material with the internal circuitry of the unit 5 The unit must not operate in presence of heating sources caustic vapors oil steam vibration orimpactetc 6 Use clean soaked cloth cleaning SPECIFICATIONS DISPLAY Type 7 segment LED Height 0 5 Counter 6 digits Rate 4 digits RANGE Counter 9999 99 99999 9 amp 999999 Rate Auto ranging 4 00 to 9999 RPM ACCURACY Rate 0 05 2 count SCALE FACTOR Programmable from 0 00001 to 9 99999x10 n 3
