H8051/H8053
INSTALLATION GUIDE
OPERATION
The H8051 and H8053 pulse output meters combine microprocessor-based kWh
transducers and high-accuracy split-core instrument grade current transformers (CTs)
in one unit. The H8051 is a single CT version designed for balanced loads, and the
H8053 is a 3-CT version for monitoring each phase. Integration of electronics lowers
hardware and installation costs. The sensors automatically detect phase reversal, so
CT load orientation is not a concern. The CTs and meters are calibrated as a set, so it is
necessary to color-match the CTs and voltage leads when installing.
These devices are used in tenant submetering, performance contrac ting, and
departmental costing applications. The 1% total system accuracy conforms to
ANSIC12.1 metering standards.

INSTALLATION
Disconnect and lock out power to the enclosure before
installation.
The Enercept meter, including the current transformers (CTs), voltage connection
fuses, and fuse pack, is permitted within electrical distribution equipment
including but not limited to panelboards, switchboards, motor control centers, and
transformers. Carefully review the equipment in which the Enercept meter will
be installed. Consider the following installation conditions during the installation
process:
Review the equipment enclosure for ventilation openings. Wires will cross
•
many of these openings in a normal installation; however, do not install
the Enercept where it will substantially block ventilation openings in the
enclosure.
• The Enercept meter and the wiring installed within a wiring space or
gutter should not exceed 75% cross sectional ll at the Enercept meter
parts as addressed in the NEC. Improper installation of Enercept meter in
the wire gutter of equipment may aect the thermal performance of the
equipment.
•
Consider the arrangement of CTs within the equipment to ensure
adequate bending radius of conductors.
• Review the arrangement and location of the CTs within the equipment.
Do not create undue strain on the conductor. A CT may require
appropriate support in order to address such a condition.

INSTALLATION GUIDE
4. Attach the pulse output wires as shown. Observe (+) and (-) polarity. Insulate any
exposed wiring.
5. Check power reading (these calculations are approximations only).
Expected power:
single-phase kW = Volts x Amps x PF / 1000
3-phase kW = Volts x Amps x 1.732 x PF / 1000
kW = Horsepower x 0.746
Seconds per pulse:
S = kWh pulse setting
seconds/pulse = (3600 x S) / kW
1. Set the DIP switches for the desired pulse rate as shown. Not all settings are
allowed for each model.

2. Connect the voltage leads to the conductors, at a location that is not normally
turned o. Connect voltage leads on the line side of the conductor to ensure
constant power to the meter. See the
Wiring section.
3. Snap the CT onto the conductor. If the
application can exceed 20 times the
rated CT current, use wire ties to secure
the I-bar to the CT housing. This CT
automatically detects phase reversal, so
CT load orientation is not important.

INSTALLATION GUIDE
NOTES
1. Insulate all output cable wires to prevent accidental contac t to high voltage
conductors.
2. Mechanically secure the output cable where it enters the electrical panel.
WARNING: After wiring the 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!

DIP switch setting.
• CheckthateachCTisinstalledontheconductorwith
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.
• ItdoesnotmatterwhichsideoftheCTfacestowards

• Ifcurrentisbelow7%offullscalemaximumforthe

•Ifusingthesingle-phaseH8051,useanamp-clamp
to ensure that all three phases are passing the same
approximate current. If phases are unbalanced, try the
H8053 model.
Voltage leads must be connected on the Line side of
the conductor. The power meter cannot communicate
without voltage.
• IftheLEDblinksquickly(i.e.,about5blinksintwo

incorrect or the CT used is too small.
• IftheLEDblinksslowly(i.e.,about1blinkpersecond)
the CTs are not installed on the correct conductors,
or the 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.
• IftheLEDblinksslowly(i.e.,about1blinkper
second), the monitored load might be less than 10%
of the CT maximum ratings.
