USC Wiring Examples
Figures 4 & 5
show typical wiring of inputs
and outputs of the USC.
Figure 4
shows the
wiring of typical devices such as photo light
sensors, wall switches, and occupancy
sensors. In addition, operating power is
provided to the photo light sensors by the
in15V dc source on TB1. The
maximum distance a switch input can be from
the USC is 500-feet using 18 AWG stranded
wire.
Figure 5
shows wiring of two banks of
electronic ballasts into the analog inputs on
TB1 of the USC. Thermostats may also be
connected to analog inputs & outputs.
