6.2 Main Power Board Connections (continued)
D. Connect the three AC main power wires (Phases A, B and C) to their
respective positions as labeled on terminal block TB1. After all conduc-
tors are connected to each of their respective terminal block positions
and tightened to 7 in-lb, verify that each terminal block screw is securely
fastened by gently tugging on each conductor. Verify that no conductor
wires are frayed or shorting to adjacent terminal block positions. For
single phase connection: connect two ac main power wires to phases a
and b and a jumper wire from b to c - factory installed for the Single
Phase option.
E. Turn ON the AC main power input. The meter display will light up and
scroll through 6 displays. Each display is visible for 5 seconds. Display
screens are as follows:
Screen 1 - Total kilowatt-hours (kWh) consumed
Screen 2 - Peak demand (kW) with date & time stamp
Screen 3 - Actual load (kW)
Screen 4 - RMS Amps
Screen 5 - RMS Volts Phase to Neutral
Screen 6 - RMS Volts Phase to Phase
Screen 7 - Power factor (PF) per phase
F. Verify the voltage readings on Screen 5 using an AC voltmeter. Typical
readings shown below are measured phase to neutral (L-N) for 4 wire
and phase to phase (L-L) 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.
