6.2 Main Power Board Connections (continued)

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 or single-phase option 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 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 six 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 (kW Load): 

Should read 0.0 kW load. 

Screen 4 (Amps per Phase):  There should be 0.0 on all three phases. 

Or in the SP option - 0.0 in A and B phases.

Screen 5 (Average AC Volts):  See Step F. 

Screen 6 (Average AC Volts):  See Step F. 

Screen 7 (Power Factor): 

There should be 0.0 PF on all three phases.

Or in the SP option - 0.0 in A and B phases.
