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.
6.4.2 Current Sensor Wiring
Once the current sensors are installed onto their appropriate phase conductors, you
can begin terminating the current sensors onto the Green Class Net main board. The
current sensors can be extended up to 500 feet for remote monitoring applications. To
extend the length of the wires, use #22 AWG twisted-pair wire with one white and one
black wire.
The easiest way to connect the current sensors is to use the meter’s built-in current
sensor diagnostics. To do this, there must be at least 1% of the meter’s current rating
(amps) fl owing in each of the conductors being monitored. The Green Class Net
meter’s diagnostic program will provide data to ensure that the current sensor
installation is done properly.
The current sensor connection points are located at the bottom right of the main power
board. These are terminals 5 through 10 of terminal block TB1. Each sensor connects
to two terminals, one labeled “Black” and the other “White.” Current sensors should be
connected to the meter one at a time and verified using the current sensor diagnostic
program.
Connect one of the current sensors to TB1 terminals 5 and 6 (Phase A). Wait 5
seconds and look at the meter display.
