The H8030 and H8031 single-phase power transducers monitor energy parameters
from aggregate kW (demand) and kWh (consumption) to power factor. With two
platforms to choose from (Energy Only or Enhanced Data Stream), the applications
for the H8030/31 Series are diverse, including energy management, performance
contracting, demand limiting and cooling plant optimization.
The H8030/31 Series combines a microprocessor-based power meter and a high
accuracy split-core instrument-grade current transformer (CT) in a single unit.
Because the electronics are integral to the CT, and power can be monitored on up
to 63 loads using a single RS-485 drop, hardware and installation costs are greatly
reduced.

installation
Disconnect and lock out power before installation.
1.
Choose a Modbus address not currently in use and set this address
using the Address Selection Switches on the bottom of the CT (see
Product Diagram).
2.
Connect the voltage leads to the conductors, at a location that is not normally
turned off. Connect voltage leads on the Line side of the conductor.
3.
Snap the CT onto the conductor.
If the application can exceed 20
1
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
orientation is not important.
4.
Connect the RS-485 wires (observe polarity).
5.
For information regarding software setup, see the Modbus protocol specifications
available at www.veris.com/Modbus/
6.
Check power reading. Expected power:
kW = Volts x Amps x PF / 1000
kW = Horsepower x 0.746
ex.: 2.4 kW = 240 VAC x 10 Amps x 1.0 / 1000
