Installation Instructions for

300 Watt Recessed Magnetic Transformer

120 Volt Input to 12 Volt Single Feed Output

SAVE THESE INSTRUCTIONS!

GENERAL INFORMATION IMPORTANT SAFETY INSTRUCTIONS

- RISK OF FIRE: This product must be installed by a
qualified electrician. Turn the power to the electrical box off
during installation. Read the "Important Safety Instructions"
before installation.

- This product is suitable only for indoor dry locations and
approved for the use at any height above the finished floor.

- This product may be dimmed only with a low voltage
magnetic dimmer. Using a dimmer other than specified may
work initially, but will eventually cause transformer failure
and void the warranty. The dimmer must be derated as
indicated by the dimmer manufacturer.

- Do not install this lighting system in a damp or wet
location.

- Do not conceal or extend bus bar conductor through
building wall.

- To reduce the risk of fire and burns, do not install this
lighting system where the insulated 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.

- A typical installation is shown. Specific installation must be
in accordance with the local electrical codes.

- TO REDUCE RISK OF FIRE, it is important to wire the
recessed transformer for the system as described in this
installation instruction.

- Load the circuit of the recessed transformer to MAXIMUM
300 Watt.

- This product may require some modification (remodeling) to
existing wall where the transformers is to be mounted. The
wall studs should be 16" apart.

- Do not install fixture assemblies closer than six inches, or
as specified in the fixture installation instructions, to
curtains or similarly combustible materials.

- Turn the electrical power off before modifying the lighting
system in any way.

- The fixtures used with the Edge Lighting systems must be
identified for use with the corresponding Edge Lighting
systems.

- Minimum volume of the electrical box must be 6 cubic
inches (98 cubic centimeters).

- The system is "ETL" listed for USA and Canada only when
all the products used are supplied by Edge Lighting.

1: Install two THHN low voltage wires from the transformer

to the electrical box to which the power feed canopy will be
attached. Run the proper size wire using the "Low Voltage
Wire Size" chart below.

NOTE: Smaller wire sizes other than specified will result in an
increase voltage drop and will reduce the lamp intensity.

NOTE: The THHN wire sizes specified in "Low Voltage Wire Size
Chart" are for 3% or less drop in voltage based on 300 watt

loads. Lengths are the distance from the recessed transformer
to the system power feed connector, or power feed canopy.

2: Insert one low voltage wire into the secondary terminal
marked "COM" and tighten the screw firmly.

3: Insert the second low voltage wire to the "T2" tap terminal
(default) and tighten the screw firmly.

4: 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 Chart" to reconnect the second low voltage wire.

1: Select the location between the wall studs (16" apart) where
the transformer is to be mounted.

2: Place the transformer between the studs and fasten it to the
studs through the bracket holes with four #8 or #10 screws
(not provided).
