For a single-phase panel with the 120V variant of the meter:
• Connect meter terminal A to the voltage disconnect phase A (red wire)
• Connect meter terminal B to the voltage disconnect phase B (black
wire)
• Connect meter neutral terminal to neutral bar in the voltage disconnect
panel (white wire)
• Connect earth wire to earth post using lug provided
• Meter terminal C is not connected
• Install power supply shorting jumpers (see Figure 6)
The PowerLogic EM4833, EM4880 and EM4805 meters are rated for direct
input of 120V to 277V 60Hz phase potential. When metering services greater
than 120V, the meter is powered from a separate 120V instrument
transformer. Figure 9 shows the wiring of the control voltage transformer for
a service between 240V and 277V.
