arrow with the
concave portion
of the terminal
to insert the
connector.
Colored clips
Connect the cords
to each of the same
color jacks.
Refer to Sections 4.3 through 4.5 on the Instruction Manual.
5. Wiring Voltage Cords to the Measuring Object
1
Refer to the wiring diagram to check the locations
to which the voltage cords have to be connected.
2
Attach the voltage cords to the secondary side of
the breaker.
3
Check the vectors and measured values.
4
Check the declared input voltage.
In completion of the wiring
,
values will be set automatically.
If the values are different from the actual values
,
change the
values.
5
Check the wiring judgment.

6. Wiring Current Sensors to Measuring Object
1
Refer to the wiring diagram to check the
locations to which the current sensors have to be
connected.
2
Attach the current sensors around the wires
connected to the secondary side of the breaker.
3
Verify that the measured values are displayed.

Tip
Set the current range based on the maximum load current expected to ow during the measurement period.
(Consult the operating status
,
load rating
,
breaker rating
,
and other data to make this determination.)
If the range is too low
,
the instrument will experience an overrange event during measurement. The error component increases if the
range is too high. Current cannot be measured accurately in any of the above cases.
Refer to Sections 4.7 and 4.8 on the Instruction Manual.
