Catalog Numbering System
The PI System is available in sections up to 8' in length for continuous row wiring by simply plugging the sections
together. Each PI section is factory wired to the ballast leads. Color coding of wires is as follows:
PI-1 = One Circuit - 2 Wires: one black, one white
PI-2 = Two Circuits - 3 Wires: one black, one blue, one white
PI-3 = Three Circuits - 4 wires: one black, one blue, one red, one white
When ordering the PI2/PI3 System it is necessary to specify the number of fixtures required for each circuit. Each circuit in
fixture must be ordered as a separate line item, with a different hot wire color specified. All wiring to external feeds, using
cord or cord & plug, are responsibility of installing licensed contractor. Cord and cord & plug sets must be ordered
separately if PI option is chosen.
