Installing the Controller
Low-Voltage Cable
Each low-voltage lighting cable consists of two parts. One part of
the cable is designated to carry the voltage load and 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 luminaires via the common side of the cable
and returns back to the transformer 15 V tap via the other half of
the cable, thus completing the circuit.
Cabling Methods
Within each cabling zone, you may utilize any number of cabling
methods. The primary objective is to minimize voltage drop by
installing the proper size feeder cable (home run) to each zone,
and to make sure each luminaire on each cable run is receiving
10 to 15 V. Center feeding the home run (the main cable run from
the transformer to the first luminaire on the circuit) will help
minimize the voltage differential between the first luminaire and
the last luminaire on the cable run.
Connecting Cables at the Terminal Block
The controller includes two common lugs and two 15 V hot 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 one of the 15 V hot lugs.
