LOW VOLTAGE WIRES
1
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.
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.
2
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
3
terminal (default) and tighten the screw firmly.
Measure the voltage at the primary power line coming
4
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.
