Severe injury or death can result from electrical shock during contact with
high voltage conductors or related equipment. Disconnect and lock-out
all power sources during installation and service. Applications shown are
suggested means of installing sensors, but it is the responsibility of the
installer to ensure that the installation is in compliance with all national
and local codes. Installation should be attempted only by individuals
familiar with codes, standards, and proper safety procedures for high-volt-
age installations.
NOTE: This equipment has been tested by the manufacturer and found to
comply with the limits for a class A digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against
harmful interference when the equipment is operated in a commercial envi-
ronment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction
manual, may cause harmful interference to radio communications. Operation

VOLTAGE LEADS
Connect the leads to the three-phase source to be monitored. Input
range is 208 to 480V.
MANDATORY FUSE PER NEC
Maximum current draw is 60 mA. Fuses provided by factory are rated
1/2A., 600V, 200kAIC. For continued protection, replace only with same
type and rating.
N2 BUS
Connect to an N2 Trunk. Please refer to wiring diagram on next page.
STATUS LED
The LED blinks green when the product is functioning normally. It will
blink slowly, approximately one second on, then one second o.
If the LED is red and blinking slowly, it may indicate incorrect wiring or a
power factor that is less than 0.5. If the LED is red and blinking fast the
CT's maximum current rating has been exceeded.
ADDRESS SELECTION SWITCHES
Each device on the N2 BUS must have a unique address. These switches must
be set to assign an individual address before the device is connected to the
N2 BUS. CAUTION: If an address is selected which conicts with another
device on the N2 BUS, both devices will be unable to communicate.
EXTERNAL CTs
These external CTs are permanently attached and must not be
disconnected and/or used with other power meters.

INSTALLATION - WIRING DIAGRAM
Choose an address number which is not in use and set the switches
for that address as shown in Figure 4. Only addresses 1 to 63 may be
used. This address will be required when adding the hardware object
at Metasys.
Disconnect power and lock-out all power sources during installation.
DO NOT CONNECT VOLTAGE INPUTS LIVE!
Connect the voltage leads to the phase conductors, as shown in Figure
2. Since the meter requires voltage to communicate, connect the leads
to a location which is not normally switched o. Connect the red lead
to the conductor most convieniently located to physically mount the CT
with the N2 BUS connector. After selecting the conductor for the red
lead, the black and yellow leads may be attached to either of the other
two conductors.
Attach CTs to conductors. Each CT must be attached to the same
conductor as the correspondingly colored voltage lead. (See wiring
diagram above) The unit will automatically detect phase reversal, so it
is not important to orient a particular side of each CT towards the load.
1Remove the terminal block and attach the N2 BUS. Positive (N2+),
negative (N2-) and REF wires must be connected as shown in
Figure 3.
If necessary, insulate any exposed N2 wiring. Ensure that the
insulation complies with local and national electrical codes. When
installing multiple meters, attach all N2 BUS connectors to the net-
work trunk cable as shown in Figure 3, then connect the individual
meters to the trunk.
Set up Metasys (see page 6).
Approximate Check of Power Reading:
1. Check actual current with Amp clamp.
Expected power is:
kW = Volts x Amps x 1.732 x PF ÷ 1000
kW = Horsepower x .746
This should be compared with value read by AI-2.

When monitoring devices controlled by variable frequency drives,
always connect the meter(s) to the line side (NEVER the load side).
CONNECTING H8000 SERIES METERS TO THE LOAD SIDE OF A
VARIABLE FREQUENCY DRIVE WILL PERMANENTLY DAMAGE THE
ELECTRONICS!
Note: The meter cannot communicate on the N2 bus without power.
Therefore, it is best to connect the voltage leads ahead of switching devices.

NOTES
1. DO NOT GROUND THE N2 BUS REFERENCE INSIDE THE ELECTRICAL PANEL.
All N2 lines, including the shield should be insulated to prevent accidental contact to high voltage conductors.
2. The N2 BUS cable should be mechanically secured where it enters the electrical panel.
3. All N2 BUS devices should be connected together in a daisy-chain fashion.
4. The N2 BUS cable should be shielded twisted pair wire BELDEN 1120A or similar.
WARNING: After wiring the N2 BUS cable, remove all scraps of wire or foil shield from the electrical panel.
This could be DANGEROUS if wire scraps come into contact with high voltage wires!

Note 1: Phase A corresponds to the Red Lead. Phase B corresponds to the Black Lead. Phase C corresponds to the Yellow Lead.

1. Dene a hardware object
Type ”N2 Device“, Device type: "VND"
2. Add kWH Accumulator (Consumption) Point
Directly map BI point 1 to an accumulator (ACM) object at Metasys.
Refer to the Range/Value column in the point map (page 4) for the
"pulse constant" which corresponds to the CT size used. The correct pulse
constant must be used to obtain accurate data. The "Rate Constant"
should be "Hour".
3. Add kW (Instantaneous Demand) Point Directly map AI point 2 to an Analog
Object. Do not use alarm or warning limits (see below). Alternatively, the
CS model le H8025.DDL may be used.
4. Add kWH AI Point (optional)
Directly map AI point 1 to an analog object. Do not use alarm warning
limits. Alternatively, the CS model le H8025.DDL may be used. This AI
point provides direct kWH accumulation display.
H8025 TYPICAL METASYS SETUP
Setting Alarm or Warning Limits
The H8025 and H8026 do not support alarm and warning status reporting
for AI points. If alarm and/or warning limits are required, rst dene a CS
object. Then map an AD object to each CS object AI point value attribute.
However, alarm and warning limits may be used with the accumulator point.
Resetting the kWH Accumulator
Point BO-1 provides a “reset button” that will cause the kWH accumula-
tor to reset when commanded to “1”. This point will automatically return to
“0” immediately after the kWH accumulator is reset. BO-1 should be directly
mapped to a BO object dened with the auto restore ag set to “N”. This
will prevent an accidental kWH reset if themeter goes o-line and returns.
BO-1 should not be dened with a CS Model, because the CS Model would
automatically set the auto restore ag to “Y”.
Using Multipliers to Scale Data Points
High voltage installations where the meter is powered by a potential
transformer will require the data to be multiplied by the ratio of the
transformer used. Most of these applications use pre-installed 5 amp output
current transformers, with the 5 amp line wrapped many times through the
H8025/H8026 meter. Two multipliers exist, one for the voltage, and one for
the eective current ratio. For example, a 300:5 amp CT is pre-installed and
the 5 amp loop is wound 20 times onto the H8026 meter; eective current
ratio would be 3. If a 20:1 potential transformer is used, then voltage points
would need to be multiplied by 20, current points would need to be multiplied
by 3, and power points would need to be multiplied by 60. Power factor points
do not use multipliers.
The kWH accumulator may be multiplied by changing the “pulse
constant”.
To apply multipliers to AI points, use a GPL process to do the math and
write the multiplied value to a pseudo-point.
H8026 TYPICAL METASYS SETUP
1. Dene a hardware object
Type ”N2 Device“, Device type: "VND"
2. Add kWH Accumulator (Consumption) Point
Directly map BI point 1 to an accumulator (ACM) object at Metasys.
Refer to the Range/Value column in the point map (page 5) for the
"pulse constant" which corresponds to the CT size used.
The correct pulse constant must be used to obtain accurate data.
The "Rate Constant" should be "Hour".
3. Compile the CS model le (H8026.DDL) to add the CS models for
the H8026 to your Metasys database. Type "DDL H8026".
4. Add CS Object using the model “H8026A”
This allows access to the rst 16 AI points.
5. Add CS Object using the model “H8026B”
This allows access to the remaining AI points.
SPECIAL METASYS SETUP OPTIONS
Displaying kWH
Use totalization to display kWH values. When displayed normally, the
accumulator will show kW instead of kWH. The kW value associated with the
accumulator should agree with AI-2, but it will respond slowly as Metasys®
counts kWH over a period of time to compute kW. Alternatively, AI-1 provides a
direct view of the accumulated kWH. For large values, BI-1 will provide better
precision than AI-1.
Presetting the kWH Accumulator
In some cases it may be necessary to preset the kWH accumulator to
a specic value. This can be accomplished by writing to ADI-1 and ADI-2.
Computing the values to write to these points is not simple. Divide the desired
kWH value by the kWH/count constant that corresponds to the CT size of the
meter (see the point map), and round o to the nearest whole number. This is
the “raw count”. Divide the raw count by 65536 and round down to the nearest
whole number. If the value was greater than 32767, subtract 65536. This is the
value to write to ADI-2. Take the raw count, divide by 65536, subtract out the
integer portion, leaving only the part to the right of the decimal point, and then
multiply by 65536. If the value was greater than 32767, subtract 65536. This
is the value to write to ADI-1. Both points should be written when there is no
power (AI-1 reads zero) to prevent the values from changing unexpectedly
as they are written.
Using the Avg/Min/Max Points (H8026)
The Average Real Power (AI-5), Minimum Real Power (AI-6), and Maximum
Real Power (AI-7) points measure their respective data during a period of time.
They begin after BO-2 is commanded to “1”. A typical usage would be to read
these points at a regular interval, such as every 15 minutes, and then command
BO-2 immediately after reading them. BO-2 should be directly mapped to a BO
object dened with the auto restore ag set to “N”.

ADDRESS SELECTION SWITCHES
FIGURE 4
Each device on the N2 BUS must have a unique address. These switches must be set to assign a unique address before the device is connected to the N2 BUS.
If an address is selected which conicts with another device on the N2 BUS, both devices will be unable to communicate.
When setting the N2 BUS address, choose an address number which is not in use. Only N2 addresses in the range of 1 to 63 may be used. Set the switches for
the selected address by following the diagram below. This address will be required when adding the meter to Metasys®.

TROUBLESHOOTING
Problem: STATUS LED does not blink.
Solution: Check fuses and voltage connections. STATUS LED should blink
regardless of CTs, N2 BUS connections and DIP switch setting.
Problem: Power meter interferes with another device on the N2 BUS .
Solution: Set DIP switches to a dierent N2 address which is not in use.
Problem: Readings seem highly inaccurate.
Solution: • Check that each CT is installed on the conductor with the
corresponding color voltage input lead attached. In most cases,
incorrect wiring will cause the STATUS LED to blink RED (slowly).
However, a Power Factor lower than 0.5 could cause the LED to
blink this way, even if the unit is installed properly.
• It does not matter which side of the CTs face towards the load.
• Check actual current with Amp clamp.
Expected power is:
kW = Volts x Amps x 1.732 x PF ÷ 1000
kW = Horsepower x .746
PF is usually 0.7 to 0.95 depending on the nature of the load.
• Compare this to the value read by AI-2
• If current is below 7% of full scale maximum for the CT, a
smaller CT should be used for very low currents. An alternative is to
wrap each wire through each CT multiple times
Problem: Meter o-line when load is switched o.
Solution: Voltage leads must be connected on the Line side of the
conductor. The power meter cannot communicate on the N2 BUS
without voltage.
Problem: STATUS LED blinks red.
Solution: • If the LED blinks quickly, approx. 5 blinks in 2 seconds, the CT
used is too small. A larger CT current rating is required.
• If the LED blinks slowly, approx. 1 blink in two seconds, the CTs
are not installed on the correct conductors, or the loads Power
Factor is less than 0.5. The meter can accurately measure these
low PFs, but few loads operate normally at such a low power factor.
