Selecting a
Location
Whether you plan to install the RS Monitor in a control enclosure
or on an adjustable arm, the first step is to select an appropriate
location for the unit. This is the most important aspect of installa-
tion because the location you select can affect the monitor’s
performance, ease of use, and life-expectancy. This section
provides some guidelines to follow when selecting a location for
the monitor.

sure that provides fire protection.
2. The monitor must be mounted in an enclosure that meets a
NEMA 4 rating.
