Installing the Luxor Transformer
Low-Voltage Cable
Each low-voltage lighting cable consists of two parts. The part
of the cable that carries the voltage load is referred to as the
Common lead. The Common lead is installed into one of the
two COM terminal blocks. The other wire lead is installed into
one of the two lugs labeled 15 V. Voltage is carried out from the
transformer to the xtures via the Common side of the cable and
returns back to the transformer 15 V tap via the other half of the
cable to complete the circuit.
Cabling Methods
Within each cabling zone, you may utilize several cabling
methods. The primary objective is to minimize voltage drop by
installing a properly sized feeder cable (home run) to each zone,
and to make sure all xtures with ZD Technology on each cable
run are receiving 10 to 15 V (or 11 to 15 V for xtures with ZDC
Technology).
Connecting Cables at the Terminal Block
Transformer terminal block: The Luxor Controller includes two
Common lugs and two 15 V lugs.
Common Lugs: One conductor from each cable run coming from
the lights to the transformer must be connected to one of the
common lugs. The other conductor will be installed into the 15 V
hot lug.
