Calibration LED : 15000 imp/kWh for -/5A CUTOUT DETAILS WIRING DIAGRAM The Panel Meter is installed on the cabinet’s front panel and shall be secured firmly with cabinet using 4 transparent Clips. The meter shall be wired as per the following wiring Diagram : 2 Use 0.5 to 2.5mm Cable for Voltage 2 2 terminals & 3mm to 6mm cable for Current terminals. +0.8 92 -0.0mm 3Phase, 4Wire Electronic kWh Meter CT-2E k wh 18 +0.8 92 -0.0mm 90mm P1 S1 P3 S3 FUSE 0 .5A REAR VIEW L1 I1 L2 kWh L3 96mm N CAL P2 S2 G S I2 S1 S2 S1 S2 I3 S1 S2 1 PULSE = 1 kWh HPL-SOCOMEC 96mm Fig. 2 S, G = PULSE OUTPUT Fig. 3 MULTIPLIFACTION FACTOR Actual Reading = Meter Reading x M.F. M.F. = CT Primary / CT Secondary (5A) Example: If the reading on the meter is 37.5 kWh. CT’s connected are of the rating 100/5A. M.F = 100 / 5 = 20 Actual reading = 37.5 x 20 = 75 kWh Ref: HPL / CT - 2M / 1007 N L1 L2 L3 LT AC THREE PHASE, FOUR WIRE PANEL MOUNTED STATIC KWH METER WITH COUNTER DISPLAY TECHNICAL PARAMETER ENCLOSURE Compact Weight : : 96mm x 96mm x 90 mm 300 gms. : : : COUNTER with 6 digits 8mm x 4.8mm IP 54 : : : : -/5A < 0.5VA 10ma (for 5A Secondary) 7A : : 120V AC to 300V AC Phase to Neutral <1 W per phase : Self Powered, No Auxiliary Supply required : Class 1.0 : : : 100 msec minimum 1 Pulse = 1 kWh interrogated with an external DC Voltage of 5V to 24V : : -100C to +550C 95% FRONT PANEL Display Digit Height Protection Index INPUTS A.
