2.1 Main Power Board

Connections to this board include the MAIN Power Input and current sensors. The
MAIN Power Input terminals are positions one through four on the four position screw
terminal block, TB1. These terminals are covered with a protective shield for safety
purposes. The current sensor assemblies interface to the TB2, TB3 and TB4. Each
terminal block corresponds to an input voltage phase; care must be exercised to
ensure that each current sensor is connected to the correct terminal block. One three
terminal screw connector(TB42) is provided for RS-485 communications. One RJ-45
jack (J8) is provided for 10/100-base T Ethernet.

The contact is a solid-state switch for the phase-loss alarm function. Switching is
limited to 100 ma (0.1 amp) and voltage should not exceed 60 Volts AC or DC.

The (N.O.) contact closes within the meter due to the loss any one of the three lines of
voltage inputs to the meter. The contact closure may be used to activate an audible
alarm, light, control coil, or other indicator device. This alerts appropriate personnel to
the loss of voltage. An emergency phone dialer may also be programmed to send
notification automatically by phone, text, or pager. Alarming devices to be supplied by
others and are not included by with the E-Mon Class 5000 meter.

One two terminal screw connector provides phase loss alarming.

There are also two headers present for adding option cards. Header J3 is 20 positions
for use with an I/O board with up to two relays, two pulse inputs and two pulse out puts.
Header J4 is a 10 positions for use with modem and LonWorks TP/FT-10.

6.2 Main Power Board Connections

1. Installing a temporary ground for ESD protection: With all circuits de-energized,
connect a temporary protective earth ground connection for ESD protection.
Prior to performing any unit wiring, be sure to discharge any static on your per­son.

2. Installing the Class 5000 protective earth ground: Connect an earth ground wire
to the Class 5000 protective earth ground lug with a torque of 7 N-m. * for meters
in metal enclosures.

Failure to attach the protective earth ground wire securely to the meter creates
a potential shock hazard. Do not operate the meter without a protective earth
ground connection securely installed.

3. Wire Entry: One 3/4” conduit opening is located on the bottom of the unit enclo­sure. This opening is used for bringing in MAINS power and for current sensor
wiring. Route the appropriate cabling to and through the respective enclosure
opening.

4. After installing the conduit fitting and conduit, verify that each conduit slip nut is
securely tightened to its respective conduit fitting. Any unused openings must be
sealed with a UL rated plugging device suitable for the rating of the enclosure
(check formatting).

NOTE: Metallic enclosure has one additional 1/2” conduit opening at top of unit.

CLASS 5000 METER

c. External Switch Mechanism/In-Line Fuse Installation.

To ensure a safe installation, the Class 5000 meter requires an external
switch mechanism, such as a circuit breaker, be installed on the Class 5000
MAINS input wiring. The switch mechanism must be installed in close prox­imity to the meter and easily reachable for the operator. This device must
also be marked as the disconnecting device for the Class 5000 meter. Install
1/10 Amp Slow Activation in-line fuses with the suitable voltage rating for
each conductor phase at the MAINS input to the meter. The fuses must be
labeled to indicate voltage and current rating as well as element characteris­tics. The fuse element must be slow activating type.

d. Connect the three AC main power wires (Phases A, B and C) to their respec-

tive positions as labeled on terminal block TB1 and tighten to 7 in-lb. After all
conductors are connected to each of their respective terminal block positions
and tightened down, verify that each terminal block screw is securely fas­tened by gently tugging on each conductor.
NOTE: On Single phase connections: Connect two AC main power wires to
phases A and B - Connect jumper from B to C - factory installed for “-SP”
option. Verify that no conductor wires are frayed or shorting to adjacent ter­minal block positions.

e. Turn ON the AC main power input. The meter display will light up and scroll

through 7 displays. Each display is visible for 5 seconds. Display screens are
as follows:

Screen 1 - Total kilowatt-hours (kWh) consumed
Screen 2 - Peak demand (kW) with date & time stamp
Screen 3 - Actual load (kW) with preset date & time
Screen 4 - Average current (amps) per phase
Screen 5 - Average voltage (volts) per phase
Screen 6 - Average voltage (volts) phase to phase
Screen 7 - Power factor (PF) per phase

f. Verify the voltage readings on Screen 5 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.

6.3 Phasing of Line Voltage

The 3-phase AC power input must be in proper phase sequence. Single phase “-SP”
option - AC power input must be in 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.)

Wait for the meter display to scroll to the voltage display. Verify that the meter reads
correct voltages on all three phases. Repeat Step 6.2.5.F.

Once the meter displays the correct line voltages and there are no error messages,
you are ready to connect the current sensors to the meter. Before continuing with the
installation, verify that the seven screens display as follows:

Screen 1 (kWh): Should read 0.0 kWh; if not, should be reset.

Screen 2 (kW Peak Demand): kW peak should read 0.0 kW. There will not be a

date/time stamp yet. If there is a kW peak recorded,
it should be reset later.

Screen 3 (Load/Clock Calendar): Should read 0.0 kW load.

Screen 4 (Amps per Phase): There should be 0.0 on all three phases. Or

in the SP option - 0.0 in A and B phases.

Screen 5 (Volts RMS Phase to Neutral): See the section 6.2.5.F.

Screen 6 (Volts RMS Phase to Phase): See the section 6.2.5.F.

Screen 7 (Power Factor Per Phase): There should be 0.0 PF on all three phases.

Or in the SP option - 0.0 in A and B phases.

NOTE: The meter will be reset later via the software during “startup” procedures.

CLASS 5000 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. 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 speci­fied, 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.

Fig. 7. Split Core Current Sensor.

2. Reassemble the current sensor assembly around the conductor(s) to be moni­tored. 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 con­ductor being monitored and MUST be pointed in a clockwise direction around
the conductor being monitored. Tighten the nylon clamp to complete the assem­bly.

LOAD

SOURCE

Fig. 8. Installation of 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 Class 5000 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 Class 5000 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.

62-0392-03 18

CLASS 5000 METER

6.4.2 Current Sensor Wiring (continued)

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

NOTE: The 1-Phase option will only display errors for A and B.

Refer to the section on Current Sensor Diagnostics for assistance in troubleshooting
these errors.

CT ERROR: A B
CT ERROR: A C

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.
