DIN-MON™ SMART METER
c. The terminal cover has breakable teeth to let the wires feed through, break
the teeth as needed. Replace the terminal cover and secure in place.
d. Energize the AC main power input. The meter display will light up showing
the startup screens, then scroll through the following screens. Each display is
visible for 5 seconds.
Display screens are as follows:
Screen 1 - T otal kilowatt-hours (kWh) consumed
Screen 2 - Peak demand (kW) with date & time stamp
Screen 3 - Present load (kW)
Screen 4 - Current (amps) per phase
Screen 5 - Voltage (volts) phase to neutral (for WYE service)
Screen 6 - Voltage (volts) phase to phase
Screen 7 - Power factor (PF) per phase
e. Verify the voltage readings using an AC voltmeter. Typical readings shown
below are measured phase to neutral for 4-wire and phase to phase for 3-
wire. Readings should be +/- 10% of nominal.

120/208V, 3ø, 4 Wire
120/240V, 1ø, 3 Wire
127/220V, 1ø, 3 Wire
120V, 1ø, 2 Wire
277/480V , 3ø, 4 Wire
277V, 1ø, 2 Wire
240V, 3ø, 3 Wire
400V, 3ø, 4 Wire
480V, 3ø, 3 Wire

NOTE: For 3-Wire (Delta) systems, the voltages are measured Phase to Phase.
For 4-Wire (Wye) systems the voltages are measured Phase to Neutral.
Delta meters are powered by Phases A and B. Wye meters are powered
by Phase A to Neutral.
