Wiring the 480V Power Supply
480V Power Supply
Connect one phase to the L1 terminal and the other phase to the L2 terminal. You
can use the same wires from the grid that the voltage inputs use (see diagram
above).
The power supply G (ground) terminal must be connected to the same point as the
meter
terminal.
Protective Fuses
The 480V power supply requires 100 mA fuses on the L1 and L2 terminals. These
should be IEC type T slow blow fuses.
N OTE
100 mA fuses can be shared with the voltage inputs.
Powering Up the Meter
After the power supply is attached to the meter, and its wiring is connected:
1. Reconnect and energize all wiring that was disconnected when the meter was
prepared for power supply installation.
2. Power up the meter and verify correct operation.
