Remove transformer cover by loosening the two Phillips
screws on the side of the transformer.
Install low voltage wires from the transformer to the
electrical power feed box to which the power feed canopy
will be attached. For best performance, use the wire size
from the voltage drop chart below.
Connect the 12 Volt Low Voltage Wires
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
(Dimension ).

Check The System
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 Wilmette 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.
Replace the transformer cover and tighten the two Phillips
screws on the sides of the transformer.
