Wiring Measurement Circuits
This section explains how to wire single-phase two-wire, single-phase three-wire, three-phase
three-wire and three-phase four-wire circuits. An impedance network is used for a flicker test.
Because the impedance network is not used for a harmonic current test except for some special
cases, connect the AC power supply directly to the SOURCE terminals of this product.
Input phases (channels) are L1, L2 and L3. L1 is the reference phase for measurement. Be
sure to wire L1.
Circuit Diagrams
This section shows individual types of measurement circuits. For actual wiring, refer to the
connection table and wiring diagram in the section explaining "Wiring Measurement Circuits".
Single-phase two-wire circuit
WARNING
•
This work has a risk of electric shock. For the AC power supply used for the
measurement circuit, be sure to disconnect the power cord from the outlet, turn off
the switch on the switchboard to which the power cord is connected, and turn off the
POWER switch.
CAUTION
Terminal G of this product is not a protective conductor terminal. It is not grounded even if
the wire is connected to terminal G. For terminals G and N, the respective SOURCE and
LOAD terminals are short-circuited internally.
