4.3.1 Installing the Split-Core Current Sensor Assembly
Each phase being monitored will require one two-piece current sensor assembly.
Therefore, a three-phase meter will require three (3) assemblies. Open the two-piece
current sensor assembly by releasing the nylon clamp using a flat head screwdriver.
Fig. 4. Split-Core Current Sensor Assembly.
1. Reassemble the current sensor assembly around the conductor(s) to be moni-
tored. Ensure the current sensor halves marked “Load” are both facing the load
side of the conductor. The colored arrow will be on the source side of the con-
ductor being monitored and MUST be pointed in a clockwise direction around
the conductor being monitored. Tighten the nylon clamp to complete the assem-
bly.

IMPORTANT:
When looking from the source side of the conductor(s) being monitored, you
should see the arrow on the current sensor assembly. The arrow should be
pointing in a clockwise direction around the conductor(s) being monitored. If
the arrow is not positioned on the source side, inaccurate readings will result.
