2.10 Wiring the Circuit under Measurement When Using Current Sensors
Connecting to the WT332E/WT333E
In the wiring examples that follow, the WT332E/WT333E input elements, voltage input terminals, and
current input terminals are simplified as shown in the following figure.
WT332E/WT333E
Also, the wiring example is for when a shunt-type current sensor is connected. When connecting
a clamp-type current sensor that outputs voltage, substitute the shunt-type current sensor with the
clamp-type current sensor.

Wiring Example of a Single-Phase, Two-Wire System (1P2W) with
a Shunt-Type Current Sensor
The following wiring example shows how to configure the wiring to connect to input element 1. To
configure the wiring for other input elements, substitute the numbers in the figures with the appropriate
element numbers.
