Wiring the 480V Power Supply
Use18 to 14 AWG |
(0.8mm2 to 2.1mm2) wire |
Use18 to 14 AWG (0.8mm2 to 2.1mm2) wires
Connections to the L1 and L2 terminals can come from V1 and V2
100 mA fuses on L1 and L2
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.
NOTE
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.
