Install a conduit from the transformer to the electrical
box.
For the best performance, use the "Low Voltage Wire
Size Table" on page 2 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.
Install the low voltage wires from the transformer to the
electrical power feed box.
Insert one low voltage wire into the "COMX" terminal
and tighten the screw firmly. Mark this low voltage wire
in the electrical box as "COM1".
Insert the second low voltage wire into the "X2" terminal
tap (default) and tighten the screw firmly. Mark this low
voltage wire in the electrical power feed box as "HOT1".
Insert the third low voltage wire into "COMY" terminal
and tighten the screw firmly. Mark this low voltage wire
in the electrical power feed box as "COM2".
Insert the fourth low voltage wire into the "Y2" terminal
tap (default) and tighten the screw firmly. Mark this low
voltage wire in the electrical power feed box as "HOT2".
Connect the 120 volt power line wires at the panel.
Measure the voltage at the power line wires 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" below to reconnect the second
and fourth low voltage wires.

WARNING: - Risk of Fire The terminal taps are not
for boosting the transformer low voltage power, they
are selected to ensure power output voltage based
upon power line conditions. Never use a higher
terminal tap to compensate for voltage drop, this may
overheat the low voltage wires and transformer. It is
recommended to use the wire size as indicated on
"Low Voltage Wire Size Table" on page 2 to avoid
excessive voltage drop.
