SmartEnergy Monitor Considerations

Safety

CAUTION - Any task requiring the removal of the electrical panel cover MUST be performed
by an electrician or qualified individual. All local electrical codes and rules must be obeyed.
Every effort has been made in providing for the safe and secure installation of the
SmartEnergy Monitor. The installation of the SEM-1024 requires the removal of the cover of
the main electrical circuit breaker panel. After the circuit breaker panel cover has been
removed, the potential hazard of shock, burn, or even electrocution now exists.
Do not attempt to complete this installation unless you are very familiar with the electrical
components and operation of the circuit breaker panel. Even when the main circuit breaker
has been turned to the "OFF" position, certain areas within the circuit breaker panel may still
be electrified. Do not attempt installation unless you know where these electrified areas are.
WARNING - These servicing instructions are for use by qualified personnel only. To reduce
the risk of electric shock, DO NOT perform any servicing other than that contained in these
operational instructions, unless you are qualified to do so.

Before You Start

Do not begin installation until you have read the "Safety" section of this manual, and read all
instructions before beginning the installation.
Estimated Installation Time:
professional installer—dependent on the number of current transformers, number of
SmartEnergy monitors, single-phase or 3-phase installations, and the complexity of the
energy-monitoring configuration.
All wiring in the United States must be installed in accordance with the latest adopted edition
of the National Electrical Code (ANSI/NFPA 70, NEC) and state or local requirements. All
wiring in Canada must be installed in accordance with the latest adopted edition of the
Canadian Electrical Code (CSA C22.2 CEC, Part I) and any provincial or local requirements.
The SEM-1024 setup includes the following:

Installation Site

Ensure the SEM-1024 installation site provides adequate ventilation for proper cooling and
space to access the SEM-1024 panel connectors. If mounting on the wall, Savant
recommends using the supplied mounting brackets.

Limitations

Review the following SmartEnergy Monitor operational limitations.
Current Transformers (CTs)
• SEM-1024 is only suitable for services of 200 Amps or less, or 400 Amps with parallel
200A feeds.
• SEM-1024 is only suitable for services with maximum 350 MCM conductors.
Note: MCM = A circular mil (CM) is a figure that represents the cross-sectional area of
a circular-section conductor whose diameter is one mil (i.e. one-thousandth of an
inch). Common MCM sizes in the electrical trade are 500, 350, 250, and the circular
mil is a measurement unique to North America.
• If your main circuit breaker or fuse panel is larger than 200 Amps, SEM-1024 WILL
NOT work.
• If your main service circuit conductors (wires) are larger than 1-inch diameter, SEM-
1024 WILL NOT work.
• Savant recommends that you DO NOT increase the lengths current transformer leads,
which are 8 feet. Increasing the lead lengths may cause inaccurate measurements.
The lead lengths can be decreased without causing inaccurate measurements.
Power Supply
• If you have a 230V AC 50Hz service typical in most areas outside North America,
SEM-1024 WILL NOT work.
Important: The SEM-1024I (International) version is required for 230V AC 50Hz
installations.
Installation
To install the current transformers, voltage sensors and SmartEnergy Monitor (SEM-1024)
unit, do the following:
IMPORTANT - Turn off all power to the circuit breaker panel by turning off the main
breaker or main switch.
1. Turn off all power to the circuit breaker panel.
2. Remove circuit breaker panel cover by following the SAFETY instructions.

Installing and Connecting the Current Transformers (CTs)

CAUTION - Only use Savant suppled current transformers with the SEM-1024/SEM-
1024I. All Savant current transformers are internally shunted (333 mV at rated current),
and therefore, inherently safe compared to other commercially available CTs. In
addition, they are also calibrated for optimal performance with the SEM-1024/SEM-
1024I.
CAUTION - If this is a combination panel, the lugs on the primary side of the main
breaker are probably still hot.
CAUTION - The CT installation along with any other task requiring the removal of the
electrical panel cover MUST be performed by an electrician or qualified individual. All
local electrical codes and rules must be obeyed.
