H663 Series
Split-Core Branch
Current Monitor
OPERATION
Designed for the critical load monitoring such as Co-location Data Centers and
lighting panels, the H663 series monitors current on up to 42 branch circuits in
a 120/208/240 VAC electrical panel. By individually reporting current draw and
initiating capacity warnings and alarms, the H663 series allows the user to manage
loading and eliminate power disturbances caused by overloaded breakers.
The H663 series consists of a data acquisition system board and up to 42 individual
split-core current transformers (CTs). The acquisition board should be mounted in-
side the electrical panel, or in an enclosure mounted near enough for the CT output
leads to reach the acquisition board connectors. The CTs are clipped onto each of the
branch circuit conductors. These CTs transmit amperage data from each monitored
circuit to the acquisition system for processing.
Current and alarm information is transmitted to the user’s Control Data Acquisition
system over an RS485 drop using the Modbus protocol.
Set-up is made easy with a PC based configuration tool which allows for global or
individual selection of breaker size, warning levels, and alarm levels.
The H663 Series is a UL508 Listed open device without enclosure.
*For 240VAC Power connection versions, order catalog number H663SM-xxE

DANGER OF ELECTROCUTION:
BE CERTAIN THAT EVERY
CT IS CONNECTED TO A LOAD AT ALL TIMES WHEN CLAMPED TO AN ENERGIZED
CONDUCTOR. Current mode Current Transformers (CTs) such as those used
in this product can be damaged, or generate lethal voltages, if clamped
around current carrying conductors while the output leads are not prop-
erly terminated to a shorting device, or loaded, as by the H663SM main
board.
Install wiring connectors in accordance with manufacturer's specifica-
tions and instructions.
• Potential electrocution hazard exists. Installing sensors in an energized
electrical panel, or on any energized conductor can be hazardous.
CT
outputs should not be connected to Operator Accessible circuits.
• Read instructions thoroughly prior to install
• This product is not intended for life or safety applications.
• This product is not intended for installation in hazardous or classified
locations and must be installed in an electrical and fire enclosure in accordance
with EN 61010-1.
Severe injury or death can result from electrical shock during contact with high
voltage conductors or related equipment. Disconnect and lock-out all power
sources during installation and service. Applications shown are suggested means
of installing sensors, but it is the responsibility of the installer to ensure that the
installation is safe and in compliance with all national and local codes. Instal-
lation should be attempted only by individuals familiar with codes, standards,
and proper safety procedures for high-voltage installations.
