Class 3200 Meter - E-Mon

CLASS 3200 METER6.2 Main Power Board Connections (continued)D. Connect the three AC main power wires (Phases A, B and C) to their respectivepositions as labeled on terminal block TB1. After all conductors are connectedto each of their respective terminal block positions and tightened to 7in-lb, verify that each terminal block screw is securely fastened by gently tuggingon each conductor. Verify that no conductor wires are frayed or shortingto adjacent terminal block positions.E. Turn ON the AC main power input. The meter display will light up and scrollthrough 6 displays. Each display is visible for 5 seconds. Display screens areas follows:Screen 1 - Total kilowatt-hours (kWh) consumedScreen 2 - Peak demand (kW) with date & time stampScreen 3 - Actual load (kW)Screen 4 - RMS AmpsScreen 5 - RMS Volts Phase to NeutralScreen 6 - RMS Volts Phase to PhaseScreen 7 - Power factor (PF) per phaseF. Verify the voltage readings on Screen 5 using an AC voltmeter. Typical readingsshown below are measured phase to neutral (L-N) for 4 wire and phaseto phase (L-L) for 3 wire. Readings should be +/- 10% of nominal.Meter Type Nominal Voltage Limits (+/- 10%)208V, 3ø, 4 Wire 120 VAC (L-N) 108 to 132 VAC480V, 3ø, 4 Wire 277 VAC (L-N) 249 to 305 VAC600V, 3ø, 4 Wire 347 VAC (L-N) 312 to 380 VAC240V, 3ø, 3 Wire 240 VAC (L-L) 216 to 264 VAC480V, 3ø, 3 Wire 480 VAC (L-L) 432 to 528 VACNOTE:Meters are powered by phases A and B.
