device: Never apply more than 12VAC/VDC to any lead or
damage will result.
5. Avoid locations where excessive moisture, corrosive fumes,
or vibrations are present.
See Table 40, and refer to Digital Ready component
details on page 51 and the job-specific electrical
drawings before proceeding with field power and control
