920RT121C
GENERAL PRODUCT INFORMATION:
This product is ETL listed and suitable only for indoor dry
locations and approved for use at any height above the
finished floor.
This product may require some modification (remodeling) to
existing wall where the transformer is to be mounted. The
wall studs should be 16" apart.
A typical installation is shown. Specific installation must be
in accordance with local electrical codes.
This product is suitable for dry locations only.
This product may be dimmed only with a low voltage
magnetic dimmer. Using a dimmer not designed for low
voltage magnetic applications may work initially, but will
eventually cause transformer failure and will void the
warranty. The dimmer must be derated as indicated by the
dimmer manufacturer.
This product is intended for use with Tech Lighting low
voltage lighting systems only.
During installation, make sure all power connections are
tight.
Read all instructions thoroughly. Read "Important Safety
Information" on page 4 before proceeding with the
installation.

C AUTION — RISK OF FIRE
This product requires installation by a qualified
electrician. Before installing be sure to read all
instructions and TURN THE POWER TO THE
ELECTRICAL BOX OFF.

Install the Transformer
Select the location between the studs (16" apart) where
the transformer is to be mounted.
Place the transformer between the studs and fasten it to
the studs through the bracket holes with four #8 or
#10 screws (not provided).

Install two low voltage wires from the transformer to
the electrical power feed box to which the power feed
canopy will be attached. Run the proper size wire using
the low voltage wire size table.
LOW VOLTAGE WIRES
Insert one low voltage wire into the secondary terminal
marked "COM" and tighten the screw firmly.
Insert the second low voltage wire to the "X2" tap
terminal (default) and tighten the screw firmly.
Measure the voltage at the primary power line coming
into the transformer. If the voltage is not in the range
of 115 - 120 volt, then pick the proper terminal tap
using the "Terminal Tap Table" to reconnect the second
low voltage wire.
Install drywall.
NOTE: Other wire sizes that comply with electrical
code can be used, but may result in an increased
voltage drop and reduced lamp intensity.
NOTE: The THHN wire sizes are for 3% drop in
voltage based on 300 watt loads. Lengths are the
distance from the transformer to the system power
feed connector.

COVER
After installing the entire low voltage system, if the
lamps have low intensity, then measure the voltage at
the fixture closest to the power feed contacts with a
voltmeter. The system must be at least 80% loaded
and the voltmeter should read between 11V - 12V
~AC. If the voltage does not fall in this range, call
Tech Lighting "Technical Support" at 847-410-4606.
Operate the system for five minutes. On the low
voltage side, all electrical connection spots should be
cool to the touch. If a connection is hot to the touch,
retighten the connection and check to ensure that the
temperature decreases.
Place the transformer cover and tighten all four
provided Phillips screws on the front.

Important Safety Information
Do not conceal or extend bus bar conductors through a
building wall.
Do not install this lighting system in a damp or wet location.
To reduce the risk of fire and burns, do not install this
lighting system where the uninsulated open bus bar
conductors can be shorted or contact any conductive
materials.
To reduce the risk of the system overheating and possibly
causing a fire, make sure all the connections are tight.
Do not install fixture assemblies closer than six inches to
curtains or similarly combustible materials.
Turn the electrical power off before modifying the lighting
system in any way.
The fixtures used with the system must be identified to be
used with the corresponding system.
Minimum volume of the electrical box must be 6 cubic
inches (98 cubic centimeter).
The system is "ETL" listed for USA and Canada only when all
the products used are supplied by Tech Lighting.
It is important to wire the remote transformer for the system
as described in these instructions.
Load the circuit of the remote transformers to no more than
the maximum rated capacity as specified.
