electrician. Before installing be sure to read all instructions and TURN THE POWER TO THE
ELECTRICAL BOX OFF.
GENERAL PRODUCT INFORMATION:
This transformer is ETL listed for use with low voltage lighting systems of brands offered by Encompass Lighting Group.
A typical installation is shown. Specific installation must be in accordance with the local electrical codes.
This product may be dimmed only with a low voltage electronic dimmer. Using a dimmer not designed for low voltage electronic applications may work initially, but could 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 Encompass Lighting Group brands of low voltage lighting systems only.
During installation, make sure all power connections are tight.
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 for use with the corresponding system.
Minimum volume of the electrical box must be 6 cubic inches (98 cubic centimeters).
Read all instructions thoroughly. Read "Important Safety Information" on next column before proceeding with the installation.

Size Table" below to select the wire size.
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% or less drop
in voltage based on 300 watt loads. Lengths are the distance from the transformer to the system power feed connector.
