RISK OF EQUIPMENT DAMAGE

• Enercept meters are rated for use at 50-60Hz. Do not connect this product to circuits with
high harmonic energy, such as Variable Speed Drives (a.k.a. Variable Frequency Drives,
Adjustable Frequency Drives) or similar sources, as these may permanently damage the
product.

Failure to follow these instructions can result in overheating and permanent

equipment damage.

QUICK INSTALL

Disconnect and lock out power to the enclosure containing the
conductor before installation.

1. Set the pulse rate switches located on the bottom of the CT(s).

2. Connect the voltage leads to the source to be monitored.

NOTICE

• This product is not intended for life or safety applications.

• Do not install this product in hazardous or classified locations.

• The installer is responsible for conformance to all applicable codes.

• Mount this product inside a suitable fire and electrical enclosure.

FCC PART 15 INFORMATION
NOTE: This equipment has been tested by the manufacturer and found

to comply with the limits for a class A digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not installed and
used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference in which case

Modifications to this product without the express authorization of
Veris Industries nullify this statement.

For use in a Pollu tion Degree 2 or bet ter environment only. A Pollut ion Degree 2 environme nt must
control conductive pollution and the possibility of condensation or high humidity. Consider the
enclosure, t he correct use of ven tilation, thermal pro perties of the equ ipment, and the relatio nship
with the env ironment. Installat ion category: CAT II or C AT III

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.
