MCP3909 / dsPIC33F 3-Phase Energy Meter Reference Design
DS51723A-page 14
Step 1: Connect the meter to 220V line and load
The diagram below shows where the voltage and current connections should be made.
It is not required to connect all 3 phases for the meter to be operational.
220VAC should be placed between either V
The AC load for a given phase should then be connected to the I
phase.
FIGURE 1-2:
Step 2: Turn On Line/Load Power to the Meter
Turn on the power to the energy meter. D1 should be lit showing the meter has power.
At this point, if a load is connected and the meter is measuring power, the power LED,
D1, should be blinking.
