is properly closed. The conductor should be in
the inside of the CT Window. See Figure 3.
Figure 3. Installed CT.
4. Repeat Steps 1 through 3 if you are using more
than one CT.
5. (Optional) Use two zip ties to secure the CT to
the conductor by wrapping one zip tie around
each of the CT's mounting brackets. This will
ensure that the CT does not slide on the
conductor once installed. See Figure 4.
Figure 4. CT with Zip Ties Installed.
6. Connect the white wire on the CT to the positive
terminal (+) on the measuring device. See
Figure 5.
7. Connect the black wire on the CT to the
negative terminal (-) on the measuring device.
No connection will be made to the shield (S)

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 CT 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.
