SmartEnergy Monitor Considerations

SafetyCAUTION - 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 StartDo not begin installation until you have read the “Safety” section of this manual, and read all instructions before beginning the installation.

Estimated Installation Time: Thirty minutes to several hours when performed by a 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 SiteEnsure 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.

LimitationsReview the following SmartEnergy Monitor operational limitations.

Current Transformers (CTs)• SEM-1024 is only suitable for services of 600 Amps or less, or 1200 Amps with parallel 600

amp feeds.

• SEM-1024 is only suitable for services with maximum 500 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 600A, 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.

InstallationTo 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.

Install the Current Transformers as follows: • The 20A and 50A CTs must be installed with the arrows pointing in the direction of the

current flow (towards the load) or away from the main breaker to maintain the correct polarity. If the CTs are not installed in this manner, the readings will be wrong.

Install one 20A or 50A CT over each required circuit output from the electrical panel by prying the clip away from the housing. After placing the CT around the power line close the CT tightly and ensure the clip snaps securely back into place.

• The 150A CTs have a label on one side. The CTs must be installed with the label closest to the source (away from the load).

Install one 150A CT over each incoming power line by pressing on the handle to open the split-core then clipping it over the power line as shown below for a single-phase installation and for a 3-phase installation.

1-Phase Installation Diagram

3-Phase Installation Diagram

1. Ensure that the two sides of the split core CTs are mated tightly together over themain in-coming power line (they should fit loosely around the wires).

2. Ensure that the two sides of each split core CT used in the installation are mated tightly together over the single or double-pole breakers.

3. Connect the split core CTs used in your specific installation to the SEM-1024 monitor(s) by plugging the 2-pin screw-down connectors from the CT leads to the mating female connectors of the SEM-1024 monitor input channels which are labeled – See Installation Diagrams.

Note - The included screw-down 2-pin connectors are added to each bare wire CT leads. These connectors are keyed and can only be inserted one way – do not force.

Installing and Connecting the Voltage SensorsThe Voltage Sensor (SEM-VT01) is a highly accurate voltage transformer that steps the primary phase voltage of 0 to 300V AC down to 0 - 0.333V AC secondary voltage. This functionality allows you to monitor the 0 - 0.333V AC secondary voltages safely with the SEM-1024.

The Voltage Sensor connector is used to measure the incoming line voltage, which allows you to take and record more accurate energy readings. The Voltage Sensors must be used when measuring bidirectional circuits and when measuring any 3-phase systems; one Voltage Sensor is required for each phase (see SEM-VT01, SmartEnergy Voltage Sensor).

For 1-phase power, the use of a Voltage Sensor is optional if higher accuracy is not required, unless you want to measure bidirectional power flow. The SEM-1024 will monitor the voltage that the AC power supply is plugged into for power calculations. In this application, it is best to plug the power supply in as close to the electric panel box as possible.

The user needs to indicate if there is a Voltage Sensor connected to the Voltage Sensor input connector on the SEM-1024. This is done by a selection of the voltage source in the RacePoint Blueprint. If there is no Voltage Sensor then select AC Power Supply.

Important - Ensure that the right side of the Voltage Sensor (SEM-VT01) output is connected to the left side of the Voltage Sensor (1, 2, 3) input connector on the SEM-1024.

Savant requires a licensed electrician to wire from the high voltage side (primary) of the main electric panel box to the voltage transformer to meet the electrical codes of the municipality.

Wiring the low voltage side (secondary) from the voltage transformer to the SEM-1024, must be done by qualified personnel only.

Note - Savant requires the installation to meet the electrical codes of the municipality.
