conductor should be in the inside of the CT
Window. See Figure 2.
4. Repeat Steps 1 through 3 if you are using more
than one CT.
5. Connect the brown wire on the CT to the
negative (-) terminal on the measuring device.
See Figure 3.
6. Connect the white wire on the CT to the positive
terminal (+) on the measuring device. See
Figure 3.
7. Connect the bare wire to the shield (S Terminal).
This reduces interference and improves the
accuracy of the CT. See Figure 3.
8. If the digital energy meter is powered, verify that
the CT LED next to the wired CT terminal block
is GREEN. If it is RED, verify that the Rogowski
Coil is on the correct phase and/or is installed
with the arrow pointing toward the load. After it is
corrected, the LED will change to GREEN.
