E-MON CLASS 3200 METER

6.4 Current Sensor Installation & Wiring

Once the AC voltages have been confirmed to be within acceptable limits, you are

ready to install the current sensors. TB2 is the input for Phase A, TB3 is the input

for Phase B and TB4 is the Phase C input. For the Single Phase option: use TB1

pos 5&6 are for the A Phase - TB1 pos 7&8 are for the B phase -factory installed

jumper wire on positions 9&10. Factory installed Jumper should not be removed.

The E-Mon Class 3200 meter is supplied with two types of 0-2V split or solid-core

current sensors (specified when ordered):

1. Split-core current sensor. This sensor opens so that it can be attached

around the circuit being monitored without interrupting power.

2. Solid-core current sensor. This sensor does not open and requires the mon-

itored conductor to be removed from the circuit to install the current sensor.

This type is only supplied when specified at time of order.

6.4.1 Installing the Split-Core Current Sensor Assembly

1. Each phase being monitored will require one two-piece current sensor

assembly. Open the two-piece current sensor assembly by releasing the

nylon clamp using a flathead screwdriver.

Fig. 7. Split Core Sensor.

2. Reassemble the current sensor assembly around the conductor(s) to be

monitored. 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 conductor being monitored and MUST be pointed in a clockwise

direction around the conductor being monitored. Tighten the nylon clamp

to complete the assembly.

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.
