security and access is controlled by the authority responsible for the location.
Ensure that the area where you install your S4820T system meets the following safety requirements:
• Near an adequate power source. Connect the system to the appropriate branch circuit protection as
defined by your local electrical codes.
• Environmental temperature between 32° to 104°F (from 0° to 40°C).
• Relative humidity that does not exceed 85% noncondensing.
• In a dry, clean, well-ventilated and temperature-controlled room, away from heat sources such as hot
air vents or direct sunlight.
• Away from sources of severe electromagnetic noise.
• Positioned in a rack or cabinet, or on a desktop with adequate space in the front, rear, and sides of the
S4820T for proper ventilation and access.
