INSTALLATION GUIDE
OPERATION
The H8035 and H8036 three-phase power transducers monitor energy parameters
from aggregate kW (real power) and kWh (consumption) to power factor per 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 electronics are calibrated as a set, so it is necessary to color-match the CTs and
voltage leads when installing. These devices monitor up to 63 loads at a time on a
single RS-485 drop.
With two platforms to choose from (H8035 Basic/Energy Only or H8036 Enhanced
Data Stream), the applications for these devices are diverse, including aggregate
billing, tenant monitoring, energy management, performance contracting, demand
limiting and cooling plant optimization.

INSTALLATION
Disconnect and lock out power 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 percent cross sectional ll at the
Enercept meter parts as addressed in the NEC. Improper installation of
Enercept meter in the wire gut ter of equipment may aect the thermal
performance of the equipment.
• Consider the arrangement of CTs within the equipment to ensure the
correct bending radius of conductors.
• Review the arrangement and location of the CTs within the equipment.
Use appropriate support for the CT to prevent undue strain on the
conductor.
ADDRESS
1. Choose a unique address and set the switches for that address as
shown in the Address Selec tion Switches section. Only addresses 1
to 63 can be used.
2. Connect the voltage leads to the phase 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 Enercept. For a
3-phase system, connect the red lead to phase A, black to phase B, and yellow to
phase C. See the Wiring section on the following page.

INSTALLATION GUIDE
4. Remove the terminal block and attach the RS-485 wires. Observe (+), (-), and
Shield polarity. Insulate any exposed wiring.
5. For information regarding software setup, see the Modbus protocol specications
available at www.veris.com/Modbus/.
6. Check power reading (these calculations are approximations only).
Expected power:
kW = Volts x Amps x 1.732 x PF / 1000
kW = Horsepower x 0.746
3. Snap the CT onto the conductor.
Connect CTs to the correspondingly
colored voltage leads. 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.
