INSTALLATION GUIDE

OPERATION

The H8025 and H8026 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 meters are calibrated as a set, so it is necessary to color-match the CTs and voltage leads when installing.

With two platforms to choose from (H8025 Energy Only or H8026 Enhanced Data Stream), the applications for these devices are diverse, including aggregate billing, tenant submetering, energy management, performance contracting, demand limiting and cooling plant optimization. The 1% total system accurac y conforms to ANSIC12.1 metering standards.

INSTALLATION

Disconnect and lock out power before installation.

The Enercept meter, including the current transformers (CTs), voltage connection fuses, and fusepac, 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. The following installation conditions should be considered 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 aect the thermal performance of the equipment.

• The arrangement of CTs within the equipment must also be considered to ensure the bending radius of conductors is not adversely aected.

• Review the arrangement and location of the CTs within the equipment. The CT must not create undue strain on the conductor. A CT may require appropriate support in order to address such a condition.

Fuse Pack

1. Voltage Leads: input range is 208 to 480V.

2. Fuses: maximum current draw 60mA. Fuses provided by the factory are rated 1/2A, 600VAC, 200 KAIC. Replace only with fuses of the same type and rating.

3. Pulse Output connector

4. Status LED: blink codes: slow green for normal operation; slow red for incorrect wiring or low power factor (less than 0.5); fast red for max. current exceedance.

5. Pulse Rate Switches: used to set the pulse output rate.

6. External CTs: permanently attached; do not disconnect or use with other power meters.

Color match CTs and voltage leads! Example: clamp the

red labeled CT around the power conductor connected to the red voltage wire.

1. Choose a unique address and set the switches for that address as shown in the Address Selection 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 meter. 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.

3. Snap the CT onto the conductor. Connect CTs to the correspondingly colored voltage lead. 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.

4. Remove the terminal block and attach the N2 BUS. Observe (+), (-), and Ref polarity. Insulate any exposed wiring. When installing multiple meters, attach all N2 Bus connectors to the network trunk cable, and then connect individual meters

5. Set up Metasys (see Metasys Setup section).

6. Check power reading (these calculations are approximations only).

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 with 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: The meter cannot communicate on the N2 bus without po wer. Therefore, it is best to connect the voltage leads ahead of switching devi ces.
