GREEN CLASS NET METER

f. Verify the voltage readings on Screen 5 using an AC voltmeter. Typical read-
ings shown below are measured phase to neutral for 4 wire and phase to
phase for 3 wire. Readings should be +/- 10% of nominal.
NOTE: Meters are powered by phases A and B. The displayed voltages will be the
measured AC voltage between phases.
6.3 Phasing of Line Voltage
The 3-phase AC power input must be in proper phase sequence. If the sequence is
incorrect or a phase is missing, there will be a message on the meter’s display: “PH
Sequence Error” or “PH Missing:. (Refer to the section on Line Voltage Diagnostics if
this message is present.) When the line voltage is connected correctly, the meter’s
display will be blank (no message.)
Wait for the meter display to scroll to the voltage display. Verify that the meter reads
correct voltages on all three phases. Repeat Step 6.2.4.F.
Once the meter displays the correct line voltages and there are no error messages,
you are ready to connect the current sensors to the meter. Before continuing with the
installation, verify that the screens display as follows:
Screen 1 (kWh): Should read 0.0 kWh; if not, should be reset.
Screen 2 (kW Peak Demand): kW peak should read 0.0 kW. There will not be a
date/time stamp yet. If there is a kW peak recorded,
it should be reset later.
Screen 3 (Load/Clock Calendar): Should read 0.0 kW load.
Screen 4 (Amps per Phase): There should be 0.0 on all three phases.
Screen 5 (Average AC Volts): See the section 6.2.4.F.
Screen 6 (Power Factor): There should be 0.0 PF on all three phases.
NOTE: The meter will be reset later via the software during “startup” procedures.
