1. Set Jumper J11 to position 2-3.
2. Set Jumper J15 to position1-2.
3. Connect the Neutral from Source to Load and to J4 (Nin) (Wye-connected systems only).
4. Connect the AC source: Phase A to J1, phase B to J2 and Phase C to J3.
5. Connect Phase A current sensor’ secondary side to J39.
a. If using a CT, enable burden resistor by closing jumper J13. Also close jumper J14 to disable
the 2nd RC circuit.
b. If using a Rogowski coil, disable burden resistor by opening jumper J13. Also open jumper J14
to enable the 2nd RC circuit.
6. Connect Phase B current sensor’ secondary side to J40.
a. If using a CT, enable burden resistor by closing jumper J19. Also close jumper J20 to disable
the 2nd RC circuit.
b. If using a Rogowski coil, disable burden resistor by opening jumper J19. Also open jumper J14
to enable the 2nd RC circuit.
7. Connect Phase C current sensor’ secondary side to J41.
a. If using a CT, enable burden resistor by closing jumper J42. Also close jumper J43 to disable
the 2nd RC circuit
b. If using a Rogowski coil, disable burden resistor by opening jumper J42. Also open jumper J14
to enable the 2nd RC circuit
8. Always refer to the IC data sheet for proper connections according to the desired configuration.
9. Write the corresponding value of the CONFIG register to the MAX78630+PPM according to the
configuration and the choice of sensors.
Note: If a phase is backwards, reverse the current flow through the respective current sensor.
