Quick "How To" Guide
1. Ensure correct model was chosen for Current Input
Type: 5 amp or low-voltage 333mVAC.
2. Mount the monitor to a DIN rail using integrated
mounting clips on backside of power monitor.
3. Connect non-energized 3 phase input voltage (term.
2-4, neutral 1 if used) . 1 amp fuses are recommend-
ed. Tighten all terminals to 5-7 inch-pounds.
4. Connect Current Transformer Inputs (term. 5-10).
The white wire (or X1 terminal) from a CT is posi-
tive or phase indicator (6-8-10).
5. Select baud rate, network address
6. Connect network output (term. 11-13)
7. Connect power supply (term. 16-17)
8. Connect kWH pulse output if needed
9. Energize the monitor and primary circuit.
10. Set CT ratio and KWH type using buttons below
the display.
