f. Verify the voltage readings on Screen 7 using an AC voltmeter. Typical read-
ings shown below are measured phase to neutral for 4 wire and phase to
phase for 3 wire. Readings should be +/- 10% of nominal.
NOTE: Meters are powered by phases A and B. The displayed voltages will be the
measured AC voltage between phases.
6.3 Phasing of Line Voltage
The three phase AC power input must be in proper phase sequence. Single phase
option - AC power input must be in the proper phase sequence. If the sequence is
incorrect or a phase is missing, there will be a message on the meter’s display: “PH
Sequence Error” or “PH Missing:. (Refer to the section on Line Voltage Diagnostics if
this message is present.) When the line voltage is connected correctly, the meter’s
display will be blank (no message).
For single phase connection: connect two ac main power wires to phases A
and B and a jumper wire from B to C - factory installed for single phase option.
Wait for the meter display to scroll to the voltage display. Verify that the meter reads
correct voltages on all three phases. Repeat Step F above.

Current Sensor Installation & Wiring
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. On the single Phase option use TB1 pos 5&6 are A - TB1 pos 7&8
are B phase -factory installed jumper wire on positions 9&10
Factory installed Jumper should not be removed.
The Green Class Net meter can only be used with two types of current 0-2V split core
or solid core 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.

H-SERIES GREEN CLASS NET METER
19 62-0424-02
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.
Fig. 7. Split Core Current Sensor.
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.
Fig. 8. Install On a Split Core Sensor.
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 meter 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 single phase
option). Wait 5 seconds and look at the meter display. The single phase option will only
display errors for A and B.
If the meter displays an error message (see below), remove the wires from terminals 5
and 6 and install them on terminals 7 and 8 (Phase B). if an error message occurs with
the sensor attached to terminals 7 and 8, try again on terminals 9 and 10 (Phase C).
The “CT Error: * “message will disappear when the current sensor is connected to the
correct terminals (phase).
Error Messages: CT ERROR: A
CT ERROR: A B
CT ERROR: A C
Refer to the section on Current Sensor Diagnostics for assistance in troubleshooting
these errors.
6.4.3 Main Power
After the meter circuit wiring has been examined for correctness, power may be
applied to the circuit board. There are three LEDs located in the upper right corner of
the Meter Board labeled BEAT, STATUS and LOAD. The BEAT and STATUS LEDs will
blink once per second when the meter is operating normally, twice per second if there
is a problem. If the monitored circuit is under load the LOAD LED will actively blink. A
heavy load will cause the LED to blink faster than a light load. Very light loads will
result in an extended blink time.
