The sign housings have holes for power and data cables as well as holes for mounting brackets (refer to
Figure 39). Wherever cables exit the housing, rubber gaskets are always used to protect the internal
components.

Referring to Figure 40, the figure illustrates the standard sign system general power and data circuits.
Depending upon each unique installation, circuit may be composed of a different number of cables of
different lengths. Although there are considerable variations in installations, the power and data each
contain the same basic components that perform the same functions from application to application.
