Split Core Current Transformers (Model NMI-TP-Series)

Please refer to the above drawing:

1. Remove and dispose of the packaging materials

2. To remove the end piece, unscrew the assembly nuts, push in on the end piece to

relieve the pressure on the bolts. Pull the bolts out and pull the end from the main U

shaped housing.

3. Position the “P1” side of the CT towards the line side of the service.

4. There are 2 screw pressure terminals labeled “S1” and “S2”. Connect the white

common 5 Amp wire to the “S2” terminal and black wire which is to the “S1” terminal.

5. The other two brass screws can be used for shunting out the CT with the use of a jumper, if

needed. Remember to remove the jumper after connecting the CT to the meter. Do not put

the CT around an energized conductor unless the CT is shunted or connected to the meter. A

open CT will vibrate and hum.

CAUTION: NMI RECOMMENDS THAT YOU TURN OFF ALL POWER BEFORE

INSTALLING CTS.
