Installation and Wiring

These diagrams are simplified. Wiring of the power monitor must comply with
all applicable codes, standards, and regulations. Protect voltage and control
power wiring with suitable overcurrent protection. Connect current transformer
(CT) secondary wiring through a suitable shorting terminal block.

Figure 11 - 3-phase, 2-wire Wye, Balanced Load

Figure 12 - 3-phase, 4-wire Wye, Unbalanced Load

IMPORTANT

In these diagrams, ‘balanced load’ configurations permit 3-phase
measurement by using only one phase connection. Unbalance in the measured
circuit affects the accuracy of the measurements.
