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 the
main 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 Sensors
The 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.
External Voltage Sensor (SEM-VT01)
Installing and Connectingthe SmartEnergy Monitor
1. Determine the best location to mount the SEM-1024 monitor.
a. Choose a location where it will not interfere with existing equipment or wiring.
b. Choose a location within the CT lead lengths (8 ft/244 cm).
c. The SEM-1024 maybe mounted using the side-mount brackets.
d. The SEM-1024 may also be mounted in an appropriate utility panel, which meets
all electrical codes for your specific region.
2. Connect the CT wiring to the Input Channels connectors and voltage sensor wiring to the
Voltage Sensor connectors.
3. Arrange and tie-wrap all the wiring in a neat and safe manner.
4. Replace the Electric Panel cover following all electrical safety guidelines.
5. Connect the Ethernet cable to the Data port on the SEM-1024 and to the Local Area
Network (LAN).
6. Connect the ground wire from the SEM-1024 grounding screw to a proper grounding
system. Savant recommends using the ground connector to achieve a greater level of
safety from electrical hazards to persons and protection from electromagnet interference
(EMI).
7. Connect the 12V AC power supply to the SEM-1024 12V AC connector and connect to
AC outlet.
Note: Source power for the 12V AC power supply must be obtained from a surge-
protected circuit.
8. Turn the power back on.
