ground. This is particularly important for sensor wires that are run in conduit
with other noise-generating conductors, such as 60Hz AC. It is strongly recom-
mended that input wiring be run in a conduit separated from AC power or output
wiring. When wire runs are long or are in close proximity to large power consum-
ing, power generating, or power switching equipment, it is highly recommended
that shielded wire be used.
Also, be sure to use the appropriate gauge wire based on the distance and sensor
type. See chart below:

When preparing wire for connection to the terminal blocks, strip 1⁄4” of insulation
from the conductor (see figure below).

NOTE: All wiring should comply with Section 17 of the UL requirements.
