Voltage Tap and Current Transformer Connections

Voltage taps and current transformers must be connected so they are measuring the same phase. They must correspond according to the following table and diagram:

Figure 1. Neurio W1 Voltage Tap Port (left) and Four CT Ports (right) on Bottom of Meter

Figure 2. Neurio W2 Voltage Tap Port (left) and CT Ports (right)


Phase	Meter Voltage Tap Port	Meter CT Port
Solar L1	A	1/A
Solar L2	B	2/B
Solar L2	B/C*	3/C
Solar L1	A	4/A

*With combined leads in voltage line harness, ports B and C are equivalent (correspond to L2).
