5. Install the current sensors onto the conductors to be monitored (Figure 5).
Sensors can be mounted facing either direction; orientation does not affect meter
accuracy. Note: Clean split-core contacts before closing. The hinge can detach,
allowing the base and the top to separate for easier cleaning and installation.
6. Plastic cable ties are included with the product for strain relief. Insert the strain
relief device into one of the available holes on the adapter board (Figure 6A).
Gather all current sensor wires connected to that adapter board and secure the
cable tie around them (Figure 6B).

Close CTs until the clasp clicks
into place to ensure that contact
surfaces are firmly seated.
7. The adapter boards are silk screened with two rows of numbers. For applications
that require odd/even branch circuit numbering, use the row designated ODD or
EVEN. For applications that require sequential numbering, use the number row
marked SEQ (Figure 7).
