Mounting
The SEM-2015 can be mounted to either a wall or similar using the pre-
installed Mounting Bracket and the included #6x1/4 PH Flat Screws.
Also the device can be mounted to a Universal Din Rail by removing
the Mounting Bracket and attaching the included Universal Din Rail
Clip on the bottom of the device.
Install Current Transformers
SAFETY CAUTIONS! Before beginning the installation process,
read through the following precautions.
–
The installation of a Current Transformer requires making
connections within an electrical panel. Savant recommends that a
licensed electrician perform the installation.
–
The install should obey all local electrical codes.
–
Only Current Transformers offered from Savant are supported.
These CT's are internally shunted and safer than other commercially
available Current Transformers
Connecting Current Transformers
Follow instructions below when installing the current transformers into
an electrical breaker panel.
1. Remove power from electrical panel by switching the main breaker
to the Off position.
2. Remove the electrical panel front cover and set aside. With a volt-
age tester, verify power was removed to the individual breakers.
3. Install the Current Transformers over each conductor being
monitored. Depending on the current transformer being used will
determine how it is installed. See below.
20 and 50 Amp Current Transformers
A. Pry the clip on the side of the Current Transformer away from
the housing and hinge open the Current Transformer.
B. Position the conductor being measured into the opening of the
Current Transformer. Close the Current Transformer ensuring the
clip on the side snaps into place.
IMPORTANT! To observe proper polarity, install the 20 and 50A
current transformers with arrows pointing in the direction of
current flow (towards the load).
C. Route the wire through a cable clamp on the side of the panel
and run wire to the SEM-2015 chassis.
150 Amp Current Transformers
A. Squeeze the handle on side of Current Transformer until the
opposite end opens.
B. Position the open end of Current Transformer over the
conductor and release the handle so the wire settles inside the
opening of Current Transformer.
IMPORTANT! To observe proper polarity, install the 150A or larger
current transformers with the label on the Current Trans-
former facing the source of the power.
C. Route the wire through a cable clamp on the side of the panel
and run wire to the SEM-2015.
4. Following steps below, install the supplied 2-pin screw down
connector onto the wires of each Current Transformer.
A. With a small slotted screwdriver, turn the screws on the
connector counterclockwise (CCW) until the silver crimps open
enough to slide the stripped wire into the square slots.
B. Strip back insulation on each wire to 1/4 inch and insert the
stripped wire into proper connection. See the Current Trans-
former and Voltage Sensor Input Polarity section for polarity
information.
C. Turn screws clockwise (CW) until the crimps tighten around
each wire. Tug on wire a bit to verify they are secure. Continue
until all Current Transformers have a connector added to it.
5. Plug the connector into the appropriate Current Transformer input
on the SEM-2015.
6. Replace the breaker panel front cover once all Current Transformers
are installed.
7. Switch main breaker to the ON position.
Voltage Transformer (SEM-VT01)
The SEM-VT01 is a highly accurate voltage transformer that reduces
the input voltage by a factor of .001. For example, if the input voltage
is 120V AC, the output of the SEM-VT01 will be .120V AC. By reducing
the voltage, the SEM-2015 can monitor individual circuits with
exceptional accuracy.
Important Information!
–
One voltage transformer is required for each phase.
–
Install SEM-VT01 voltage sensor as close as possible to the electric
breaker panel.
–
Between the voltage transformer and the SEM-2015 it is best to
have as short as a run as possible.

Install Voltage Transformer
Savant requires a licensed electrician be used to connect the SEM-
VT01 to the high voltage side. Follow instructions below to install. The
instructions assume the electrical outlet boxes are mounted and an
electric circuit is run into the box.
1. Switch the circuit breaker to the circuit that the SEM-VT01 is being
added to.
2. Using diagram below, make high voltage connections.

Sensor to each Phase
3. Screw the SEM-VT01 into the electrical box.
4. Using the supplied 2-pin screw down connectors and #18 AWG
wire, install the wires into the 2-pin connector. Refer to the
connector diagrams below when wiring.
5. For instructions on how to install wires into the 2-pin connectors,
refer to step 4 of the Install Current Transformers section.

6. Once all connections are made, switch the breaker back ON.
7. With the SEM-2015 and any optional accessories installed,
the system can now be configured in its own Web UI. For
more information see the Savant Stand Alone Energy Monitor
