H804x SERIES

INSTALLATION GUIDE

OPERATION

The H8040 Series devices combine microprocessor-based kW transducers and high-accuracy split-core instrument grade current transformers (CTs) in a single unit. Integration of elec tronics 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.

The H8041 and H8042 are for single-phase or balanced-load applications at 208V and 480V, respectively. The H8043 and H8044 are the three-CT versions of the product for use on 208V and 480V with unbalanced loads.

These devices are used in chiller optimization, performance contracting, and energy management. The 1% total system accuracy 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, 50/60Hz.

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. 4-20mA 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. External CTs (3-phase version only): 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. Connect the voltage leads to the 3 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. Connect the red lead rst to the conductor most conveniently located to the output connector. See the Wiring section on the following page.

2. Snap the CT onto the conductor. Observe color matching. 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.

3. Attach the 4-20mA output wires as shown. Observe (+), (-), and Shield polarity. Insulate any exposed wiring.

Wire tie

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

Expected power: 4-20mA response: kW = Volts x Amps x 1.732 x PF / 1000 kW demand = kW x (mA out - 4) / 16 kW = Horsepower x 0.746
