GREEN CLASS NET 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. TB1, positions 5 and 6 are the inputs for Phase A,
TB1 positions 7 and 8 are the inputs for Phase B and TB1 positions 9 and 10 are the
Phase C inputs.
The Green Class Net meter can be used with two types of current sensors:
1. Split-core current sensor. This sensor opens so that it can be attached around
the circuit being monitored without interrupting power. Unless otherwise speci-
fied, all Green Class Net meters are supplied with this sensor type.
2. Solid-core current sensor. This sensor does not open and requires the monitored
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 fl at head screwdriver.

2. 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.
