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 SP 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 Class 5000 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 Class 5000 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.
