Wiring the Current Connections
Electric current is sampled as it flows through cylindrical apertures in the circular
section of the centrally mounted Digital Signal Processing (DSP) Module. There are
a t otal of si x (6) a pertures. T ypically o nly t he f irst f our ( 4) a re u sed as cu rrent
inputs f or I 1, I 2, I 3, a nd I N ( Neutral c urrent optional a s th e f ourth input).
Optionally, a f ifth ap erture m ay b e ordered f or a n ad ditional c urrent input, an d
the sixth aperture is disabled at this stage. To wire current connections:
 Install Current Transformers in series ahead of the unit
 Feed t he cu rrent l ines t hrough the cylindrical ap ertures i n t he ci rcular
section of the G4K's DSP Module:
 Verify the polarity of current conductors with the arrows on the circular
section of the DSP
