4.3 Current Sensor Installation & Wiring
Once the AC voltages have been confirmed to be within acceptable limits, you are
ready to install the current sensors. The MAIN power board contains three header
connectors located at the bottom right of the board. The connectors are labeled A, B,
and C along with conductor color indication. This format must be followed in order for
the meter to function correctly. (Phase C is not used)
The Class 1000 meter will be used with one of two basic types of current sensors:
a. Split-Core Current Sensor: This sensor opens so that it can be attached
around the circuit conductor being monitored without interrupting power.
Unless otherwise specified, all Class 1000 meters are supplied with this sen-
sor type.
b. Solid-Core Current Sensor: This sensor does not open and requires the
monitored conductor be removed from the circuit to install the current sensor.
This type is only supplied when specified at time of order.
NOTE: The unit serial label specifies if the unit is set up for split or solid core current
sensors.
Both types of current sensors output a 0-2 VAC signal proportional to the current being
measured.
