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 5)
The PowerLogic EM4033 and EM4080 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 7 shows the wiring
of the control voltage transformer for a 277V service.
